Weight is altitude.

The summit is your goal weight and the trailhead is where you started. Each morning's weigh-in feeds your 7-day average, and your climber moves to match it. One salty dinner doesn't send you back down the mountain.

Set down a stone at every flag.

Your climber carries a pack of stones. At each flag one comes out and is built into a cairn, and the pack gets lighter. Only the pack changes. Your climber's body never does.

A guide for every plateau.

When your average stalls, the Waylighter comes down from the mist. He asks a few plain questions and gives you one next step. He never suggests fasting, skipping meals or supplements.

“Steady days. That is the whole secret.”

Your weight stays on your iPhone.

No account and no server. Your weigh-ins, your plan and anything from Apple Health live on your device and are never sent to us.

The app sends anonymous usage events so we can see which screens help. Read exactly what is and isn't sent.
