iOS app · Coming soon
ComboCoach
One designer, one month, AI in the corner. What can you build?
In short
- Challenge
- Training alone at the bag can be intimidating: no coach, no plan, no idea what to throw next.
- Approach
- An audio-first iOS coach that calls combos in the boxing style you choose, inside a session you shape.
- Result
- A working app, launching soon.
Why I built it
Solo bag training can be scary. You walk up to the bag, gloves on, and then what? Nobody tells you what to throw, so you repeat the same two punches and keep checking the clock.
I box, and I’ve stood there myself. So I asked: what if you had a coach with you? One that teaches you combos, keeps the time, and doesn’t need you to look at a screen.
The thread of this story
Alone at the bag, but never without a coach.
Every decision started from one question: what would a good coach do right now? Tell you what to throw, teach you a way of fighting, and keep the rhythm, so you can just train.
01
Pick a style. The coach in the demo below will call its combos.
Coaches don’t just shout random punches. They teach a way of fighting. So ComboCoach lets you pick a boxing style: Foundations to learn the essentials, Soviet for range and footwork, Mexican for pressure and body work. More styles are on the way.
+ More styles coming soon
02
A coach in your ear
The coach calls the combinations out loud, so your eyes stay on the bag. The screen is there if you want it, with big, simple numbers you can read from a distance, but you don’t have to look at it.

The timer I always wanted
Training with it shaped the features. Choose your rounds, how long they last and how long you rest. Set it once, then forget about the clock.

Built with AI, decided by me
I designed and built the whole app in a month. I was a rookie in code, so I built it in collaboration with AI, and learned as I went.
AI helped me
- Write the code
- Learn as I built
- Move from idea to app in a month
I decided
- What to build, and why
- Every screen and interaction
- How a round should feel

Playing with AI video
These clips were more of a test than a launch campaign. I wanted to see what AI video could do with a real product in the frame, and I had a lot of fun making them.
What’s next
ComboCoach is a working app, launching soon. Get a sneak peek at combo.coach
