The deep-work performance coach

Your best hours are
costing you something
you can't feel.

Deep focus quietly suppresses your blink rate, pulls your head forward, and drains your reserves — hours before you notice your eyes burning. Deepform measures all of it, on your device, and turns it into one number you can actually move.

What's actually happening

The harder you concentrate, the less you blink.

It isn't willpower or screen brightness. Sustained near-focus suppresses the blink reflex itself — and the blinks you do make stop closing fully, so the tear film never resurfaces. That's the burning eyes at 6pm.

Illustrative curve. The endpoints are documented: a healthy resting rate is 15–20 blinks per minute, and sustained screen focus commonly drops it to 5–7. What Deepform measures is your actual line, not this one.

Why one number beats one metric

Your eyes are one of four things giving you away.

Blink rate alone is noisy. Read it alongside drowsiness, posture load and overnight recovery and a real picture appears — the one a timer can never show you.

A blink reminder watches one of these. The camera-only score stands on its own — pairing a smartwatch adds overnight recovery, it isn't required.

Take posture — the one you notice last.

Your head weighs about 5 kg. Every degree it drifts in front of your shoulders multiplies that weight by leverage, which is why the ache shows up at 6pm and not at 9am.

Approximate. The further your head sits in front of your shoulders, the more its weight is multiplied by leverage — which is why the ache arrives late in the day rather than at the start. Deepform measures your angle and how long you hold it.

Why you can trust a camera product

There's no frame to leak, because none is ever sent.

Open, not just “private”

Every wellness app claims on-device processing. Ours is going open source (Apache-2.0), so you can read exactly what runs on your machine.

Private by architecture

Sensing runs on your device and we store numbers, never video. The camera is released the moment a check ends.

Yours to export

One click exports your data as JSON or an LLM-ready summary. Take it, script it, or delete it.

What this is — and isn't. Deepform is a wellness and performance tool, not a medical device. It doesn't diagnose, and it makes no blue-light or brain-training claims. It measures physical signals — eyes, posture, fatigue, recovery. It does not infer your emotions, mood or engagement, and it never will.
