THE WHY · FREE ON EVERY NUMBER · FOR EVERYONE

It shows its working.

Most apps change your numbers and keep the reason to themselves. Compound puts it one tap away: the rule it followed and the sets it read. And a lower number always waits for your say.

Week 6
Reload
Planned for next week

Lighter week, then back on

Week 6 runs lighter so squat and bench go into week 7 fresh. The test week doesn’t move.

Squat3 of 4 reps, twice at 112.5 kg
Bench80 kg × 6, RPE 8 to 9 across three sessions
RuleTwo lifts from two families, same two weeks, once a block

Reload weeks are part of Pro. You can undo one.

What it does for your week

  • It knows how today went.

    Say Easy or Hard as you log, or say nothing: a short set or a long rest reads as hard. The next set moves.

  • The gym you’re in, the week you had.

    Rack taken? Swap for today, at the right weight. Miss a week and nothing breaks: sessions run in order, not on weekdays.

  • It only counts what went up.

    A medal every ten kilos, a club for every total you lift. Nothing for opening the app. No streaks.

  • Your story, in sets and reps.

    You train. The journal keeps the story: every best, every month, every set behind it.

  • Read it from the rack.

    The whole block is the clock. It drains while you rest and fills back for the set.

  • Back it up, take it with you.

    Back it up to a file, restore it anywhere, delete it whenever you like.

Built for how you lift

Pick the goal. The program is built around it.

  • Powerlifting

    Percentage blocks that end in a tested max, on a date.

  • Strongman

    Gym days and event days in one week, with the implements your gym has.

  • Bodybuilding

    Reps and volume by RPE, weighted to the part you want to grow.

  • General strength

    The big four on percentages, with accessories that climb.

  • Hybrid

    The bar climbs while the engine holds, then they swap. Ends in a max and a 2 km.

  • Your own plan

    Log what your coach gave you, or ask for a session built for the kit in front of you.

All of them run on your days and your gym, know whether you’re cutting or building, and deload on the block.

Free follows. Pro changes with you.

Free · for everyone
Free

A program that explains itself: starter programs, Freestyle, logging, Progress, medals and every reason.

Pro · every set adjusted

Pro builds the program for your goal and lifts it with you: every set adjusted as you lift it, maxes that rise when you’ve earned them, a reload week planned when two lifts slip, and a session built for whatever gym you’re in.

Asked before you download.

How is my data handled?

It’s all in the privacy policy.

What does Pro cost?

The app shows the price from the store, in your currency. Two weeks of Pro are free from your first session. Cancel and keep everything.

iPhone or Android?

Both. Out now on iPhone, on the App Store and Android, on Google Play.

Does it work offline?

Yes. Your program, your sessions and every reason live on your phone, so a basement gym with no signal is fine. Pro keeps working offline too.

What happens when the trial ends?

Pro stops adjusting your program, and a program you're running keeps Pro to the end of the block it's in. Nothing is lost: your history, your programs and your medals stay yours, and every reason stays free.
