About
Written journals rarely survive three days. A journal you shoot might.
tridi captures your day as three moments — morning, day, and evening.
One photo or one 3-second clip per slot. That's all.
When all three are filled, they become a 3-second vertical film
where your three moments play at once.
■ One rule: 3:3:3
- Morning 05:00–11:59 / Day 12:00–17:59 / Evening 18:00–04:59
- One capture per slot
- Missing a slot is fine. An empty slot is still part of your day.
■ No account. No server.
- Every photo and video stays on this device only
- Also saved to a 'Tridi' album in your photo library — that's your backup
- Open the app and start. No sign-up.
■ Your days become an archive
- A month at a glance, in color, on the calendar
- Share your 3 seconds anywhere
■ tridi+ (optional)
- Watermark removal, original clip storage, yearly recap film
- Your past records are never locked behind the paywall
Keep today. In three seconds.
