Fit by LevelUp

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

01THE NEED

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.

NEED

Sign-ups, announcements and the record of who had joined all lived in Viber groups.

SOLUTION

A challenge becomes a product: a start date, a price, prizes and measurements before and after. Joining is one tap.

BENEFIT

Sign-ups and results in one place, and progress shows in numbers.

NEED

Cash and bank transfers, every payment entered by hand. Useless for growth.

SOLUTION

A monthly subscription through the App Store and Google Play, with every receipt verified on our backend.

BENEFIT

Revenue arrives on its own, with no cash and no ledger to keep.

NEED

One model does not cover everyone. Some want a subscription, some want a single challenge.

SOLUTION

Coins are bought in bundles and earned by training and by referral. Challenge entry is priced in coins.

BENEFIT

A second revenue stream, and a currency that rewards turning up.

NEED

The user has to come back tomorrow, and the catalogue has to grow without a developer.

SOLUTION

A new workout every day, in the user’s own time zone. The owner uploads the videos himself.

BENEFIT

The catalogue grows without us, and the user has a reason to open the app tomorrow.

The screens come from the app in production, with demo data on them, not real users’ data.

03IN USE

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

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.
