Good idea but needs improvement
Prediction errors: When trying to make my predictions, it would not let my type numbers into the boxes. Although I’m not sure what the reason for this is, it was unable to be fixed despite closing and reopening the app, restarting phone, etc. The only two explanations I can think of for it not working are that it is only compatible for computer, or it doesn’t let you make predictions after the tournament has started. For the latter explanation, it would be useful to give a notice of this so other people don’t waste their time.
Group Rankings: This is more of a suggestion than a problem, but on the group rankings, it would be nice to show a bar of what place you are in at the bottom of the screen. It would make it so much easier to find what place you are in because instead of scrolling through all of the names looking for yours, you can see it right from the start.
TLDR: This app is a good idea with a decent format, but could use multiple improvements, like the problems with constant freezing, problems with predicting, and the group rankings.
