Who can make a simple Android app

[Germainclement]

Hi,

I develop lots of little programs for my home and now I just need a very simple app that i can use with my programs. The app should do only 2 things :
1. read a barcode
2. save it on the phone in a text file (1 barcode per file)

Important is that after each barcode is read, it is stored in a separate text file on the phone. the file must have a unique sname so preferably based on date and time (incl milliseconds)

Thats all because I can read, write and delete in an android phone so I can check these files, so I can use my phone as a barcode reader

Thanks in advance. You can contact me on my email <mod removed email, reply below or PM>

Thank you and have a splendid 2021 !
