AI workout app

Buli: an AI workout app for personalized gym training

How Buli works

Buli builds your program from what you tell it and sharpens its suggestions after every workout you log. You always have the final say.

  1. 1

    Tell Buli where you start

    Answer a few questions about your goals, experience, and training days.

  2. 2

    Get a program — or build your own

    The AI builds a gym program that fits you, or you assemble your own or your coach’s program in the app.

  3. 3

    Log your workouts

    Record sets, reps, and weights during the workout on your iPhone or Apple Watch.

  4. 4

    Get weight suggestions

    Based on your logs, Buli suggests your next working weights. Change or skip any suggestion.

  5. 5

    Watch your progress

    History, personal records, strength level, and charts show how far you have come.

Who is Buli for?

No app fits everyone, so here is an honest take on when Buli is a good choice — and when it is not.

Buli is for you if you want

  • A personal gym program instead of a one-size-fits-all template
  • Ready weight suggestions so progression never depends on guesswork
  • Your plan, logs, records, and charts in one app
  • To run your own or your coach’s program
  • To log sets straight from your Apple Watch

Buli is not the right choice if

  • You need an Android app today — the Android version is still on the waitlist
  • You are rehabilitating an injury or need training supervised by a doctor or physiotherapist
  • You want a fully automatic coach whose suggestions you never review yourself
  • Your main sport is something other than gym and strength training

What the AI does — and what it does not

Buli creates your program and weight suggestions from the information you provide and the workouts you log. A suggestion is a starting point, not a command: technique, recovery, and how you feel on the day always affect the right load.

AI suggestions can also miss. Buli is not a medical device and does not diagnose injuries or replace a doctor, physiotherapist, or coach. Every suggestion can be edited or skipped.

Train safely

  • Choose weights you can control with good technique.
  • Stop the workout if you feel pain, dizziness, or anything unusual.
  • See a professional for injuries and health conditions.
  • Treat suggestions as guidance — the final call is yours.

Questions about Buli

Is Buli a workout planner or a workout tracker?

Both. Buli can create a personalized program or hold one you enter yourself, and it logs exercises, sets, reps, weights, records, and progress.

Can Buli make a full gym program for me?

Yes. Buli builds a program from your goals, experience, and schedule, and you can edit it freely.

Can I use my own or my coach’s program?

Yes. Assemble the program in the app and use Buli for logging, weight suggestions, and progress tracking.

How do the weight suggestions work?

Buli suggests your next working weights from the sets you log and your recovery inputs. Every suggestion can be changed — the final call is always yours.

Is Buli available for Android?

Not yet. Buli is available for iPhone, and you can join the Android waitlist on this website.

What happens after the 7-day trial?

The 7-day trial requires no payment card and does not automatically become a paid plan. To continue, you choose a subscription: €7.99 per month or €69.99 per year.

No. Buli provides general training guidance, is not a medical device, and does not replace a doctor, physiotherapist, or other qualified professional.
