MOBILE TRAINING APP iOS AND ANDROID
The training is at home, the billing is in the app.
Fit by LevelUp is an online training platform built like a game. The coach publishes video workouts and opens challenges, and every challenge carries a start date, a price and a prize. People train at home, earn XP and coins for every workout they finish, and prove the result by measuring themselves before and after. Revenue arrives two ways, through a monthly subscription and through coin bundles, and the stores bill for both. We built the platform for coach Nedim Babić and shipped it in 2022.1
The challenge had a date before it had an app.
Nedim ran his training through an off-the-shelf app that could not keep up with the way he worked. Payment came in cash and by bank transfer, every one of them entered by hand, and sign-ups and announcements went out through Viber groups.
The programme had long outgrown the tool it lived in. And the next challenge was already announced in public, with ten days in the Maldives for the best result. The goal was clear: get the app out before the challenge started.
The same search, a new result.
The app that did not exist. The same search, then and now.3
BEFORE
The business ran in Viber groups, and the search turned up nothing but other people’s apps. The one he needed did not exist.
TODAY
Two revenue models and one habit.
The screens come from the app in production, with demo data on them, not real users’ data.
Fifth year, same ratings.
The best proof is not the rating but the date. Reviews have come in every year since launch, in 2022, 2023, 2024 and 2025.4
The app is great, simple and easy to find your way around. 🔝
The app is perfect. Very simple and easy to read. Everything about it is first rate!
Excellent app and excellent workouts, especially for mothers after giving birth and with small children.
This is the best training app there is. Hats off. I can hardly wait for each workout.
With this app you can always put aside 15-20 minutes for yourself, even when you are away on holiday.
TECHNOLOGY
The app outlived the project.
Fit by LevelUp has run on iOS and Android since 2022, and another team maintains it today. The handover went through without a pause, which was the whole point. The platform does not depend on the people who built it.
SOURCES Where everything on this page comes from
1 LAUNCH
The app was published in March 2022 on the App Store and Google Play. The date is on both store listings, and the first release in our own repositories matches it.
2 PHOTOGRAPH
The portrait of Nedim Babić is from radiosarajevo.ba, cropped to the face.
3 THE BEFORE AND TODAY SCENE
The cards on the right come from the store pages, with the original images. The left side is an illustration.
4 RATINGS AND REVIEWS
The public store listings, 4.7 from 724 ratings on Google Play and 4.9 from 113 ratings on the App Store. The reviews are quoted with the name and year exactly as they stand at the source. They were written in Bosnian, so on this page they are our translation.
5 THE NUMBERS
Google Play states 10,000+ downloads, and that is Android alone. The 19,000 comes from fitbylevelup.com, where Nedim writes that he has helped more than 19,000 clients through the Level Up training system. Those are not installs but people who went through his programme, and the tile says so.
6 GUEST-HOSTED CHALLENGES
The guest-hosted challenges were published in public on fitbylevelup.com. The photograph of Naida Bojnaković comes from the page of her own challenge.
