## What is TrayZen?

Forgot to wear your retainer again? TrayZen makes it impossible to lose track.

TrayZen gives you a visual daily goal ring, smart reminders that only fire when you're genuinely falling behind pace, and an editable wear history so you can fix missed taps retroactively.

Designed for Invisalign, clear aligners, and night retainers.

FEATURES

• One-tap timer with a clear daily progress ring
• Smart reminders: notified only when behind your goal, never false-positive
• Editable history: fix any missed or wrong tap after the fact
• Tray-change reminder: tracks your aligner change schedule
• Works fully offline, no account required
• No ads. Ever.

FREE FOREVER

The full timer, 30-day history, and smart reminders are free with no time limit.

PRIVACY

Your wear data never leaves your device. TrayZen requires no account, collects no personal information, and contains no ads or data-selling analytics.
