Subo keeps you honest with AI-verified photo proof. Define what counts, snap a photo, and Subo checks it against your own description — so a checked-off habit actually happened.

How Subo keeps you honest
Three taps between "I'll do it" and "I did it."
Define the proof
Write what "done" looks like — e.g. "my gym bag by the door" — so Subo knows exactly what to check.
Snap the moment
Take a photo right from the app. No digging through your camera roll — just the proof, in the moment.
AI verifies, streak grows
Subo uses Claude vision to judge pass or fail against your description. Passing proof locks in your streak.

A checkbox can lie. Subo doesn't.
Honor-system trackers fall apart because tapping "done" is too easy. Subo makes the photo the check-in, and Claude vision checks it against the proof description you wrote.
- 1Every passing photo is persisted as real evidence of the habit.
- 2Blur or hide sensitive shots before sharing with friends or groups.
- 3No facial recognition — just your proof, matched to your words.
