I need a single system that lets our production floor and office teams stay in sync on inventory. The core requirement is one code-base that ships as an Android app for tablet/phone use on the shop floor and a desktop build that staff can run in the office (web or lightweight desktop client—open to your recommendation). Key features I must see from the first release • Real-time stock tracking so every adjustment, receipt, and issue is reflected instantly for all users. • Automatic notifications whenever any item hits a predefined minimum level so we can reorder before shortages slow production. Barcode scanning is not a launch-day essential, but the database and API design should leave room to bolt it on later without a rewrite. To be considered, send a detailed proj...
The Android trivia app I’m working with serves up word puzzles presented in a “Top 10 Ranking” format. I need each of those puzzles captured accurately, run through Gemini AI for clean text extraction, then double-checked against the live screen to be sure nothing is missed or mis-read. User rankings are not required—just the puzzles themselves. Here’s how the flow should look: • Launch the app on an Android device or emulator. • Trigger Gemini AI (screen capture → OCR) to pull the puzzle text. • Manually verify the AI output; correct any anomalies. • Upload that file to my contribution portal and mark each entry as complete. I’ll provide portal access and, if needed, a short Loom demo of the extraction steps. Consistent...
Hi, I’ve attached the updated project specification PDF. Please review the entire document carefully before starting. It contains the complete requirements for the 5–10 physical Android device control center, including simultaneous live screen monitoring, device management, parallel workers, task queue, automation, recovery, logging, licensing, security, testing, and deliverables. Please let me know if you have any technical concerns or suggestions before we finalize the development plan and milestones.
I’m planning a new social media application and need a developer who can take it from concept to launch on both iOS and Android. The heart of the product is a dynamic News feed where users will scroll through posts from the accounts they follow. Each post should support rich text, images, or short videos and refresh in real time. Key interactions I want implemented from day one are Likes and comments plus the option for users to Share posts directly to their own feed. Smooth, snappy performance and modern gesture-based UI patterns are important to me, and I’d like push notifications in place for activity on a user’s content. I already have initial wireframe sketches and branding assets, so you’ll focus on the full mobile build, backend APIs, and deployment to the ...
I need a website and mobile app that integrates with multiple social media platforms to locate and display businesses on a map based on user search queries. Key Features: - Social Media Integration: - Pull in search results from Facebook, Instagram, TikTok, Google, and WhatsApp using real-time APIs. - Open to developer suggestions for additional APIs or cost-effective integration methods. - Business Mapping: - Pin businesses on an interactive map. - Provide detailed search results displayed via cards with relevant information from social media. - Comprehensive Business Listings: - Include all types of businesses (restaurants, retail stores, service providers, etc.) Additional Details: - I already have a concept designed and some APIs set up but need a developer to finalize the...
I’m creating a crypto-security platform whose very first product is an encrypted wallet-protection service. The site has to look trustworthy, load fast, and, above all, demonstrate that every private key a user stores or transacts with is handled under strong, modern encryption. From the landing page through to the user dashboard, the experience should make it clear that security is the core value we deliver. Here’s what I need built: • A responsive public site that briefly explains how our wallet protection works and why encryption is central to it. • A secure registration and login flow that leads users to their personal dashboard. • Server-side modules that encrypt all sensitive data both in transit and at rest (AES-256 or equivalent), plus an API lay...
This project centres on a cross-platform mobile application (iOS and Android) that merges the excitement of sports betting with the season-long engagement of fantasy leagues—yet keeps everything strictly play-for-bragging-rights. Users join or create private leagues, sign up for free with a basic username-and-email profile, and then submit weekly picks instead of traditional line-ups. Core game flow • At the start of each week the app publishes a fresh slate of match-ups. • League members lock in their selections across the following pick categories: – Player performance – Team performance – Game outcomes • Results update automatically after games conclude, and a dynamic leaderboard tracks cumulative points for the season. Key feat...
I’m looking for someone who enjoys building quick, lightweight Android utilities and can handle the entire cycle from coding to publishing on my Google Play Console. For the very first assignment I’d like “another small utility app” beyond the usual calculator or wallpaper examples—something simple yet useful that can be shipped fast and then refined as we collect user feedback. Here’s what I need each time we work together: • Clean, well-commented code in Java or Kotlin, built in Android Studio • AAB/APK ready for release plus the signed keystore or key management steps handled • Play Console assets prepared (screenshots, feature graphic, short description) and the app successfully published under my account • Basic after-lau...
I’m ready to move Landed from concept to a touch-ready prototype. The game is a mobile-first, multiplayer life-sim where players arrive in a new city, balance money, energy, belonging and homesickness while prices rise, run savings circles with friends, host dinners and track down hard-to-find ingredients. Although designed with diaspora and migrant communities in mind, it should feel welcoming to anyone. Engine & platform I’ve settled on Godot so the build targets both Android and iOS from a single codebase. Lightweight networking will support real-time or asynchronous play. Core systems to implement • Resource-management loop for money, energy, belonging and homesickness • Social-interaction layer that lets players form savings circles, schedule dinners ...

I am building an end-to-end AI platform: The build must cover: • iOS • Android • Web The work involves taking an excellent base model (such as Meta’s Llama or Mistral AI) and adapting it to your niche using techniques like fine-tuning or RAG (Retrieval-Augmented Generation). Adding data must also be made possible through a simple and intuitive interface. The platform must allow users to write questions and read answers, but also feature a graphical interface that enables the exchange of opinions and realistic debate with the user. What I expect from you is a fully functional, production-ready system—front-end, back-end, and model integration—delivered with clear documentation and deployment assistance so my team can scale it after launch. If you al...
I need an experienced live-chat agent to handle customer-service inquiries on my Android app during the evening hours. All conversations come through an in-app chat tool; you will log in, greet users promptly, resolve routine questions, and escalate any technical matters to our internal team. Because this is purely customer service, you will focus on account questions, basic “how-to” guidance, and reassurance rather than deep technical troubleshooting or sales pitches. A friendly, concise writing style and solid written English are essential. Deliverables: • Log in at the agreed evening schedule and stay available for the full shift. • Respond to every chat within 1 minute and follow our reply templates where applicable. • Create a brief summary ticket for ...
I want a lightweight Android app that can read the live feed of 1xBet’s Crash game and forecast the crash point a few seconds before each round stops. Mobile is the only environment I need covered, so everything you build should install cleanly on recent Android versions without side-loading gymnastics. The core of the project is the prediction engine. Whether you choose pure probability modelling, machine-learning, or a hybrid approach, the algorithm must process real-time data from the game screen or API and return a single number—the expected multiplier at which the round will bust. A simple, distraction-free interface that shows the current round, your predicted crash point, a confidence score, and a quick history log is enough for version one; fancy charts can wait. You&...

I want to launch a feature-rich social media application built natively for Android. Because the focus is Android only, the entire UX should follow Google’s latest Material Design guidance and take advantage of Kotlin (or Java if you have a strong case).

I’m building a mobile-only puzzle game for Android in which every level is a race against the clock. Players will have a clear countdown, escalating difficulty, and a fast, satisfying restart loop that keeps them chasing better times. Here’s what I need from you: • A complete, publish-ready APK plus the full project source. • Clean, touch-friendly controls, responsive UI, and a lightweight art style that performs smoothly across current Android devices. • A modular level system so I can add or tweak timed stages later without rewriting core code—Unity, Godot, or any comparable engine that supports this is fine. • Basic settings (sound/music toggle, pause, restart) and Google-Play-ready build settings. • Brief documentation outlining the p...
Our mobile app is already feature-complete and sitting in the “Near completion” phase, yet a handful of stubborn functional bugs are keeping us from hitting the publish button. I need a React Native developer who can collaborate directly with our in-house team, dig into the codebase, and resolve those issues so we can move straight to production. You’ll receive a detailed bug tracker, access to our GitHub repo, and a working build for both iOS and Android. Your role is to reproduce each functional defect, isolate the root cause, and push clean, well-documented fixes through pull requests. Daily Slack or Teams check-ins keep everyone aligned, and our automated CI pipeline will confirm that no new regressions are introduced—green builds and a crash-free TestFlight/In...
I want complete peace of mind that my personal iPhone & android Samsung is fully locked down against hackers. The job is straightforward: audit every setting, app permission, network profile, and cloud-sync option on the device; fix or guide me to fix anything that leaves an opening; and finish with a clear summary of what was changed and why. Because this is for personal use, I’m focused on practical, real-world protection rather than corporate compliance checklists. Expect to work directly with me over a secure video or messaging channel so I can follow along while you adjust settings such as Face ID, two-factor authentication, iCloud Keychain, Wi-Fi/cellular profiles, and any third-party security apps you recommend. Deliverables • A live, step-by-step hardening se...
I’m putting together an Android Studio app whose only job is to pull product records from a Postgres instance hosted on Google Cloud and show them in a clean, scrollable list. The data connection must run through Google’s Antigravity agent so the app stays lightweight and secure without shipping database credentials inside the APK. Here’s what I need from you: • A minimal yet solid Android Studio project (Kotlin or Java—your choice) that connects to the Postgres database via the Antigravity agent. • An async call that fetches product data—name, price, description, image URL are enough for a working demo—and maps it into a RecyclerView list. • Basic UI: toolbar with app name, RecyclerView list, placeholder images handled gracefully, a...
I need a secure, web-based application that streamlines every key workflow in my optics practice. The core of the platform is an electronic patient record that stores medical history, insurance information, and prescription records in one place, searchable at any time from any modern browser. A dual-mode recall engine must be built in: it should send automated SMS and email reminders while still allowing staff to step in and schedule manual follow-ups whenever needed. The same messaging layer will power day-to-day email and text communication with patients. To keep the team organised, the system also requires an integrated to-do list where tasks can be created, assigned, and tracked through completion. Deliverables • Responsive web interface with role-based access • Databa...
I run a small clinic and need a straightforward mobile application that lets my team capture, store and pull up a patient’s complete medical history at any moment. The heart of the build is a structured medical-history module linked to a prescription writer, so a doctor can open a chart, review past notes, add today’s findings, then generate and save a new prescription—all from one screen. The app has to work smoothly on modern smartphones, store data securely on-device first, and give me an easy way to back up or export records (PDF for individual visits and CSV/JSON for bulk data). A quick search by name, phone number or patient ID is critical because we often look up a file while the patient is sitting in front of us. Appointment scheduling is not a must-have right no...

I have a clear idea of the problem my app should solve but, instead of a formal brief, I will give you a set of reference materials—competitor apps, feature lists, and a few rough sketches. Your first task is to study these assets, extract functional requirements, and translate them into a structured roadmap. Once we agree on the roadmap, you will design the UI/UX, recommend the most suitable tech stack (native iOS, native Android, or a cross-platform framework), and then build, test, and package the application. Code must be clean, well-commented, and committed to a shared repository so I can track progress in real time. Deliverables: • Requirement summary distilled from my references • Wireframes or a clickable prototype for sign-off • Full source code with bu...
Based on the image you sent from the Freelancer app ("Tell us what you need done"), the text you should type into that empty box depends on what kind of project you want to post.

I have a Google account ready, all personal details prepared, and I will supply every OTP that pops up during the flow. What I cannot provide is an internationally-enabled debit card, which is where you come in. Your task is to take my account from “start registration” to a fully active Google Play Console developer account. The payment must be made with a debit card that supports international transactions, and the whole session needs to run behind an Indian IP to avoid region-related hiccups. I have included a PDF that shows the exact screens in sequence, so you can follow it step by step without guessing. Budget: 600-1500rs (~$6-15) for your help + 25$ (2411rs) for registration fees I'll provide working google account and other details. Deliverables (all mandatory...

I’m gearing up to launch a brand-new Android app that lets my hardware-shop customers browse products, add items to a cart, and place orders straight from their phones. The focus is strictly on online sales and ordering—no inventory management module for now—so every screen should guide shoppers smoothly from discovery to secure checkout. Core flow I need: • Product catalogue with categories, search, photos, prices and live stock count pulled from our existing SQL database (REST/JSON endpoint is ready). • Cart, quantity edits and promo-code field. • Checkout supporting cash-on-delivery plus at least one standard payment gateway (Stripe or Razorpay is fine). • Order confirmation, push notification updates and a simple order-history screen. &bul...

I’m creating a self-guided, two-hour tour that visitors can enjoy even when they have no signal, so every asset—audio tracks, video clips, map tiles, and imagery—must be packaged inside the app bundle and run 100 % offline once the first download completes. Core experience • As soon as the phone’s GPS detects that a traveler has reached a designated point, the matching chapter should start automatically. • Users can still tap Play or Pause at any time, scrub the timeline, or replay earlier chapters if they wish. • An interactive map (shown with the device’s live position) remains available offline and lets users jump to any stop visually. • Short quizzes or checkpoint questions pop up at selected locations to keep people engaged an...
I’m rolling out a consumer-facing mobile app and need a tester who is physically in the Philippines—Metro Manila preferred—and already has an active PH phone number. You’ll install the current build on both an Android and an iOS device you own, then walk through the full experience while we watch and discuss over a scheduled video call (Zoom or Google Meet, whichever you like). During the session we will: • review the user interface for visual or layout issues on each platform • exercise every primary function, flagging bugs or confusing flows • note any performance hiccups such as slow loads or crashes Afterwards, please send a concise report (screenshots, short clips, and step-by-step notes) summarizing what you observed, grouped by UI, fu...
I need a pair of polished mobile apps—one for iOS, one for Android—that lets a traveler open the phone, find a human agent, and finish a booking in a few taps. The entire flow should feel like messaging a knowledgeable friend: the user starts a chat, describes the trip, then reviews flight and hotel options surfaced through live API feeds before paying securely inside the app. Core experience • Dual-platform build (iOS + Android) delivered either natively or with a single codebase such as Flutter or React Native—whichever you recommend for long-term stability and speed. • Real-time messaging between traveler and assigned agent, complete with push notifications and image/file share. • Integrated flight and hotel search tied to a major GDS/OTA API so a...

I’m expanding my Mobile Legends project with a dedicated Ranked mode focused on ranking and rewards.

I need a native-Android application that reproduces the workflow now handled in my Excel sheet. The sheet records every job, lets the person doing the work enter his direct costs, and then helps me track what has already been paid and what is still outstanding. I want the same data-entry fields and the same automatic calculations migrated into an intuitive mobile interface so nobody has to touch the spreadsheet again. Two distinct roles are required. • Job performer: opens the app, chooses or creates a job, keys in labour, material or travel costs and immediately sees the calculated total for that job. • Manager/Administrator: sees every submitted job, the running balance of payments, marks items as paid, and can export a simple summary report for accounting.
