“We’ve rebuilt this three times. This cannot continue.”
[Our team, more than once]
Problem
Freeletics was four apps: nutrition, bodyweight, running, and weights. To bring weights into one app, we copied what we had and built on top. It took six to eight months, and the experience was terrible.
- Every new training type meant another rebuild, about six months each time
- Each rebuild made the new type fit the old app, so the next one was just as hard
- Freeletics couldn’t add new kinds of training fast enough to keep up







Key contributions
- Mapped and helped build the information architecture for workouts, so any exercise and any type of training work together, built for hyper-personalized training.
- Created a modular UI system for training, so the interface could scale to any type of training without new screens.
- Tested the logic with backend engineers against running, yoga and anything we’d add next.
