Customizable App for Escape Room

We own an escape room and are looking to launch an outdoor scavenger hunt/tour game. As part of the game people will need to get help/hints/clues. We would like for this to be done through an app. Basically when a can select different clues to be used. Depending on what they select determines the points it costs them. There may be up to 20 #s so around 20 clues. We need to be able to track how many clues a specific team used in a game. We also need to be able to have this reset for the next game. The app needs to be able to be modified as needed on our end.
