How we build

Thought through. Shown in plain words.

Four principles shape every screen we ship. Here's what they look like in Steel Peak.

01

The app does the thinking.

Planning a workout means juggling a lot: what you lifted last time, how you slept, what equipment you have, what hurts. Steel Peak weighs all of it, so you open the app to a plan that's ready.

  • Your logged setsWeights and reps from last time
  • This morning's check-inSleep, fatigue, stress, soreness
  • Your equipmentHome or gym
  • Pain you reportEven mid-set

Then it explains itself.

A decision you can't see is hard to trust. Tap “Why?” on any set and your coach shows its reasoning: the last weight, the next one, whether to hold or go up, and how sure it is.

Why this weight?

Stay at this weight until you complete the target reps at the planned effort; then the load goes up.

Last time 10 lb. Hold this weight. Why?

03

Private by design.

We'd rather not hold your data at all. Steel Peak has no accounts, and your training data stays on your phone. This website follows the same rule: no cookies, no analytics, and nothing loaded from anyone else.

04

Tested before it ships.

Every release runs thousands of automated checks. Then we use it on a real iPhone before it goes out. If something isn't right, it waits.

See it in Steel Peak.
