Create a Football Referee App


I need to create an Android app for football referees to use. This app must be created using App Inventor.

Functions of the app includes:

- Stopwatch

- Insert teamsheet (connect to TinyWebDB and can choose team and players instead of inputting manually)

- Make substitution of player (record which player is out and which replaced player is in)

- Store and accumulate scores for each match

- Show records of winning team in each match and seasonally

- Whistles (once, and twice in a row)

- Show Red/ Yellow card

- Store data to TinyDB

- Retrieve data from TinyWebDB

Since we are undergraduates, we don't have monthly income. Hopefully someone who want to practice or is familiar with App Inventor could give us a hand and charge us not more than 1000. Thank you!
