BackWatcher — Offline Posture Alerts for macOS
BackWatcher






Does this feel familiar by 6pm?

Long desk hours quietly build tension — until your body reminds you.

It doesn't happen suddenly. It builds slowly.

That stiff pull at the base of your neck

Leaning forward without realizing it

Shoulders feeling heavy after long focus sessions

Catching yourself slouched too late

That rounded, tired-looking posture

BackWatcher interrupts it before it turns into daily strain.

Here's what most people don't realize:




Sitting 8+ hours a day slowly reshapes your spine.

BackWatcher trains awareness.
You correct yourself — not a device forcing you.
A small alert is enough to reset your posture before it becomes a habit.

A gentle reminder helps you correct your posture.

About Us



I'm Chaker, data engineer based in Paris.

I built BackWatcher after noticing my posture degrading from long coding sessions.

The goal: create a simple, private, offline tool that reinforces healthy posture habits without wearables or subscriptions.
