Meditation you can prove you actually did
Most meditation apps measure whether you opened them. nak measures whether you sat. The front camera watches for closed eyes on your own device, and the clock stops the moment you open them.
How it works
- Pick a lengthOne minute to an hour, or an untimed mode for long sits.
- Put the phone down and close your eyesThe front camera reads one thing: whether your eyes are shut. All of it runs on your device.
- Get minutes that are realOpen your eyes and the clock stops. The number you end with is time you actually sat.
The camera question, answered plainly
No image ever leaves your device. Nothing is uploaded, stored, or reviewed — not a photo, not a frame of video, not a face template. The only thing that reaches our server is a number: how many minutes you sat and what share of them your eyes were closed. If you would rather the camera stayed off entirely, you can still sit in a mode that scores nothing.
What it costs
The app is free and carries no advertising. If you want to support it, nak pass is 99 THB (about 3 USD) for 30 days: double points, unlimited conversation with nak's AI, untimed mode, and a rainbow profile frame. 15% of that revenue goes to a stray-dog foundation.

One tree, everybody's minutes
Every minute anyone sits feeds a single bodhi tree shared by all users. The goal is 100,000 people sitting fifteen minutes each — fifteen million minutes. Nobody gets there alone.
For hotels, spas and ice-bath spaces
Guests scan a QR card in the room and sit immediately — no app to install, no staff needed, no cameras of yours involved. You get a branded page, a leaderboard for your guests, and a monthly report. Write to palapol.c@polyme.co.
Who should skip it
If you want a teacher's voice walking you through each step, or a structured course, nak is not that. It teaches nothing. It only tells you the truth about how long you sat. And if you are in real distress, talk to a person — in Thailand the mental-health line is 1323.
Frequently asked questions
Is nak really free?
Yes. The app is free and ad-free, and you can sit without creating an account. nak pass at 99 THB per 30 days is optional support, not a paywall on the practice.
Does the camera send video anywhere?
No. Eye detection runs entirely on your device. Only a number — minutes sat and the share of time your eyes were closed — is sent to the server.
What platforms does it run on?
iOS via the App Store, the full app in any modern browser, and an Android version currently awaiting Google's review.
Do I need an account?
No. Signing in only carries your history across devices and puts you on the shared leaderboard.
What does 'nak' mean?
It is the Thai word for otter. The character sitting beside you with its eyes closed is an otter.
