Just click and train
A minimalist workout generator and calisthenics tracker. Train for strength, cardio or mobility. All in the same place.
Built from a real need
I built SkillTrees because I was tired of generic workout apps. Full of ads, pop ups to buy and generic workouts. I wanted a simple way to progress in calisthenics and other sports. This app is the result: a smarter, adaptive way to train that I use myself every day.
Train for multiple goals at once
I love mixing calisthenics with other sports, but juggling apps was a nightmare, and know what to do everyday was impossible. SkillTrees lets you combine different disciplines, like running and bodyweight training, into one simple, cohesive plan.
Actually see your progress
It's hard to stay motivated when you can't see the results of your hard work. Our visual skill trees make it easy and fun to track your journey, so you always know how far you've come and what's next.
Workouts that adapt to you
Most apps give you rigid plans. SkillTrees learns from your feedback and performance to create workouts that are always interesting and just challenging enough. It's like having a plan that actually listens. Your training adapts to you, not the other way around.
Just focus on your workout
No one likes fumbling with timers or spreadsheets. The app tracks your sets, reps, and rest times automatically. You just do the work, and the app takes care of the details.
Make it your own
Not feeling an exercise? Swap it with one click. Want to add a note for next time? Easy. This is your training plan, and you should have the final say.
Why not just use a chatbot?
AI chatbots are powerful, but they aren't specialists. I built SkillTrees because I needed a tool that was 100% focused on skill progression and athletic development. That focus makes all the difference.

Frequently asked questions
It gets to know you. Based on the skills you want to learn, your performance, and even your notes, it creates a plan that's tailored to your current level. The goal is to help you improve steadily without getting stuck.
I built it to solve my own problem: I wanted to train for multiple things at once (handstands, climbing, flexibility) but couldn't find a way to balance it all. SkillTrees is designed around that idea—making progress on specific, long-term goals in a clear, visual way.
Yes, absolutely! The visual milestone tracker is a core part of the app and is completely free. It's the best way to see how far you've come and stay motivated.
Definitely. I started with zero experience (couldn't even do one push-up!), so I designed it to be the app I wish I had back then. It helps you build a solid foundation and grows with you as you get stronger.
Yes, the core features—like workout generation and progress tracking—are free. There's also a PRO subscription that unlocks more advanced features. Honestly, the support from PRO users is what allows me, as a solo developer, to cover the costs and keep building the app.
It does. I found that using AI was the best way to offer truly flexible and personalized workouts. It helps combine different sports and adapt to your notes ("make this workout shorter"), and continuously expand the exercise library. It's all about giving you more powerful, customized options.
