Sarcasm App

I would like to take a backward italic font, use a different hue, and apply this to the default keyboard for next upgrade for Android. For iOS it will be like 'emoji' where they download the app and then go Enable the feature. Both platforms should preserve the same look and feel of the keyboard although there should be a new 'Sarcasm' button (similar to B for bold) that wrties a new font to users .. now I am thinking backward Italics but with a slightly different hue .. but the point is you clearly depict you are joking via text. If the other end user does not have the font then just format to BOLD. There is no emotion behind text message besides emoji, bold, and italics .. I want something that says "I am obviously joking" yet the problem is we would be able to enable this for Android via the next release whereas we may need to rearrange the keyboard and have users download and accept the new layout .. just as they did with emoji. If we keep both as close to original as possible and virtually no difference is present to the user that would be perfect. I am a developer and am swamped so have this idea but cannot complete it on my own .. please reach out. Ah, my friend brings up a good point .. this would require a new iOS keyboard entirely to support email, SMS, etc. though my hope is to reto fit this into older iOS if possible. I get if it is not possible. The easiest thing to do is create a wrapper around both platform keyboards. Whos is up to the challenge? One final note, I would like 'Tom Sarcasm' app in both Appstore and Playstory for users to do download the font/keyboard rather than wait for an OS updated (which may never happen for some Android users) .. it basically adds the library to the font dir and sets it as default so the option shows up automatically for Android .. for iOS i think I have already accepted that they need a have a y/n disclaimer to apply this upon download. On that note, not needed, but a tutorial would be nice .. like 20 seconds of 'here is the button and what it does, okay?' but that is up to you. I can offer 200 bucks .. I do not need this and can dev myself over a weekend but have too much going on. I estimate this being a 2-3 hour project. Let me know if you have any questions .. let's test on iOS 8.4 and 9.0 since that is coming soon. Please pass over the .apk and .ipa file once complete so I can maintain this app. This should be a fun one, my friends. Cheers, Tom Copy written, so don't copy me :)
