support@trayzen.euFrequently asked questions
Is TrayZen really free?
Yes. The full app — wear timer, daily goal ring, smart reminders, 30-day history, tray-change tracker, and dark mode — is completely free with no ads and no time limit. No credit card, no sign-up, no catch.
Does it work without an internet connection?
Yes. TrayZen is built offline-first. All your wear data is stored directly on your device. You never need an internet connection to use any core feature of the app.
Do I need to create an account?
No account required. TrayZen works completely anonymously. Just download, set your daily goal, and start tracking.
Does it work for Invisalign, retainers, and other aligners?
Yes. You choose your tracking type during setup — Invisalign, Retainer, or Other. The daily goal pre-fills to 22 hours for Invisalign and 8 hours for night retainers, but you can adjust it from 8 to 24 hours in 30-minute increments.
What happens if I forget to log that I took my trays out?
You can edit your history retroactively. On the History tab, tap any day to see your sessions, then add a missing session, adjust the start or end times on an existing one, or delete an accidental entry.
How do reminders work?
TrayZen only sends a reminder when you are genuinely falling behind your daily goal. It calculates your current pace against your goal and only alerts you when you need to catch up — never at arbitrary times, never false positives.
How do I set up the home screen widget?
After downloading TrayZen, long-press your iPhone home screen, tap the "+" button, search for "TrayZen", and choose the widget size you prefer. The widget shows your live goal ring progress without opening the app.
How do I set my daily goal?
You can set your daily goal during onboarding, or change it later in Settings → Daily Goal. Drag the slider to your desired wear time, from 8 hours (night retainer) to 24 hours, in 30-minute steps.
Is Apple Watch supported?
An Apple Watch companion is coming soon. It will let you toggle trays in and out from your wrist and show your daily progress as a watch face complication.
How do I reset all my data?
Go to Settings → scroll to the bottom → Reset All Data. This clears your wear history, sessions, and preferences. This action cannot be undone.
