Hello Sir,
Good morning. Hope you are doing great.
Regarding your project related to silent app, I have done similar project (Busy time Schduler/Call Blocker),which will block incoming calls/other message/notifs during the time gap which we set as busy .
You could check my portfolio on the same (Call Blocker/Busy time scheduler)
So, I'm sure I can do this for you.
If interested,pls accept my Bid.
Looking forward for your favorable response.
Thanks
Apeetha
