DeSlouch DeSlouch

Your phone is already a posture coach.

Drop it in your hoodie's hood, strap it to your chest or back, or just wear your AirPods. DeSlouch feels the moment you start folding forward and gives you a quiet nudge — a buzz, a low tone, or both. No $100 gadget, no subscription, and your posture data never leaves your phone.

Your body's data stays on your phone. Posture readings are processed on your device and thrown away as they go; your posture history never leaves it. The app sends only anonymous usage statistics (no sensor data, no identity) so we can keep it working well — details in the Privacy Policy.
📱
Works with any phone The accelerometer already in your phone reads how far your torso has tipped forward. Nothing to buy, nothing to charge, nothing to pair.
🎧
Or with your AirPods AirPods track the tilt of your head, so DeSlouch catches "tech neck" — the slow forward creep that happens while you're reading. Works with the phone in your pocket.
🧠
Not a dumb timer It buzzes because you are actually slouching, not every twenty minutes regardless. Brief bends are ignored, and it stops paying attention entirely while you walk around.
🤙
A nudge, not a nag Pick how it feels — a single tap, a double tap, a pulse, or one long low buzz. Set quiet hours. It gives up rather than hounding you.
🧶
A strap made of string The app includes a step-by-step guide to weaving a phone strap out of about two metres of cord — worn on the chest or, better, the upper back. In a hoodie? The hood works as-is.

Simple, honest numbers Upright time, slouches caught, your longest tall streak. Enough to see progress, not enough to become another thing to manage.

How it actually works

Sit or stand the way you would like to hold yourself and tap Calibrate. That posture becomes your zero. From then on DeSlouch watches how far you drift forward of it, and when you have held a slouch for longer than a few seconds, it nudges you. Sit up and it goes quiet again.

The one thing that matters is that the phone is held flat against your body — in a hoodie's hood, strapped between your shoulder blades, or in a snug chest pocket. The upper back reads best: a slouch rounds your back more than it tips your chest. A phone left dangling on a loose cord simply hangs vertical no matter what your back is doing, and there is nothing for the app to read. The setup walks you through checking this in about ten seconds.

What it costs

Nothing. DeSlouch is free, with no subscription, no advertising and no in-app purchases. It was built because the alternative was a hundred-dollar wearable that does roughly the same thing your phone can already do.

Not a medical device

DeSlouch is a habit aid. It does not diagnose, treat or prevent any condition, and it is not a posture-correction treatment. If you have back or neck pain, or a diagnosed spinal condition, talk to a qualified healthcare professional — an app that buzzes at you is not a substitute for one.
