Why Dev Gym
AI writes more of the code. You still have to understand it.
Swift, SwiftUI, concurrency, Apple Intelligence: Apple’s platforms change every year. Meanwhile AI writes more of the implementation, which leaves you less deliberate practice reading, reviewing, debugging and explaining code.
Those are the skills a code review or an interview still asks of you. Dev Gym keeps them strong, a few reps at a time.

How a workout works
Pick a set. Do the reps. Watch the map move.
A workout is one set of five reps. Each rep asks for a different kind of thinking.
Pick a set
Choose a set from your training split, or start the one your Skill Map says is fading.
Do 5 reps
- Recall
- Predict
- Find the bug
- Review a PR
- Explain it
See your Skill Map update
Every answer moves the map. Strong areas hold, and fading ones come back for spaced review.
