Hi - it appears that both apps (google and apple) are not working and are completely missing from both app stores. We recently just bought into TroopTrack so this is a bit daunting for us as we’re trying to get parents signed up for the program this month.
The Apps don’t give any more functionallity than using the website in a browser on mobile, they are actually more limited in a few areas. I don’t believe the Android app was ever really fixed for the newest Android versions. I would suggest you have your users save a shortcut to their home screen for quick access through their browser.
