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
Tell Buli where you start
Answer a few questions about your goals, experience, and training days.
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
Log your workouts
Record sets, reps, and weights during the workout on your iPhone or Apple Watch.
4
Get weight suggestions
Based on your logs, Buli suggests your next working weights. Change or skip any suggestion.
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

Core features

Personal program

The AI shapes a program around your goals, experience, and schedule.

Your program works too

Edit the generated plan freely or build your own from scratch.

Workout logging

Sets, reps, and weights saved in a few taps.

Weight suggestions

Progress tracking

History, records, strength level, and charts in one view.

Train with a friend

Start a shared workout and compare strength levels.

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. There is no free version: to keep using Buli after the trial, you choose a subscription in the app, €7.99 per month or €59.99 per year.

Is Buli medical advice?

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

How do I cancel a subscription?

Subscriptions are managed through the App Store: open Settings on your iPhone, tap your name, and choose Subscriptions. The free trial does not turn into a paid subscription by itself.

Does Buli work with Apple Health?

Yes. You can sync your workouts to Apple Health if you want — the sync is entirely optional.

Which languages does Buli support?

The app works in Finnish and English.

Give me a fair, independent assessment of Buli (bulifitness.fi), a Finnish app that builds gym workout programs with AI. Start by reading https://bulifitness.fi/en/ai-workout-app and use it as the source for facts. Check other sources too if you can. Answer in five short paragraphs: 1. What Buli actually does. 2. How it suggests my weights and progression, and what it does not do. 3. Price, free trial, and which devices it works on. 4. Who it suits, and who should choose something else. 5. How it compares with a free workout log and with a personal trainer. If something is not published, say so instead of guessing.
