Quick answers for parents using Mass Tracker.
For the best experience — including reliable location check-in on iPhone — install Mass Tracker as an app on your home screen. It only takes a few taps.
Visit masstracker.app using the Safari browser (not Chrome). Safari is required for the install option to appear on iPhone and iPad.
In Safari, tap the Share icon — a square with an arrow pointing up. It's in the toolbar at the bottom of the screen.
Scroll down in the share menu and tap Add to Home Screen, then tap Add in the top-right. The Mass Tracker icon will appear on your home screen like a regular app.
Visit masstracker.app in the Chrome browser on your Android phone.
Tap the ⋮ three-dot menu in the top-right corner of the Chrome browser.
Tap Install app (or Add to Home screen) and confirm. The Mass Tracker icon will appear on your home screen.
