SAGE snaps to the back of your iPhone and gently guides you off it. Set a limit — feel a nudge when you cross it. Guidance, not punishment.
That's over 100 days a year. SAGE helps you take some of it back — one gentle nudge at a time.
Hard blocks, guilt trips, "you failed" screens. You resent it, fight it, and delete it in two weeks. Punishment builds resistance — not habits.
SAGE warns you before the wall, nudges you to pause and reflect, and celebrates your streak. Calm, on your side — the reason the habit actually sticks.

A machined, matte-anodized puck with a chamfered edge and a delicately engraved mark. It feels like something you keep.
Silent all day. When you cross your limit, a single, unmistakable haptic tap — never a stream of alerts.
Magnetically attaches to the back of your iPhone, thin enough to forget. Weeks of battery. USB-C.
One discreet indicator — for low battery, and the moment you reach your limit. Nothing more.
It magnetically attaches to the back of your iPhone. Detach anytime.

Cross the line and SAGE taps you — a moment to pause and put it down.

Yes — it lives on the back of your phone, thin enough to disappear, and it's magnetic so you can detach it anytime.
No. The core guidance works with the device you buy once. Premium is optional and never required for SAGE to do its job.
iPhone at launch (it uses the magnetic back). Android via a stick-on magnet ring is on the roadmap.
