An app for athletes tired of training always the same

Find goals. Get workouts. Personalize all.

Working out shouldn't be boring

I built SkillTrees because I couldn't motivate myself to workout consistently for 2 years. Working out always the same and without a clear goal. This app is the result: an adaptive way to train that I use myself every day.

Train for multiple goals at once

Combine disciplines, like running and bodyweight training, into one simple, cohesive plan.

Select skills to prioritize your training

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. We learn from your feedback and performance to create workouts that are always interesting and just challenging enough.

Just focus on your workout

No one likes fumbling with timers or spreadsheets. The app tracks your sets, reps, and rest times automatically.

Make it your own

Not feeling an exercise? Swap it with one click. 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.

AI Chatbots

Doesn't remember your history or progress.

Requires you to describe what you need, every single time.

You still have to figure out how to track your progress.

The best ones can be expensive (often $20/month).

A generalist tool, not a specialist coach.

SkillTrees

Learns from every workout to give you better suggestions.

Pick a skill, and the app maps out the steps to get there.

Built-in tracking and timers so you can stay focused.

Free version availible. Pro is just €4.90/month. It helps me cover server costs and keep improving the app!

I built this to avoid the mistakes I made, saving you time and frustration.

Frequently asked questions

How does SkillTrees personalize workouts?

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.

What makes SkillTrees different from other fitness apps?

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.

Can I track my progress over time?

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.

Is SkillTrees suitable for beginners?

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.

Is SkillTrees free?

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.

Does SkillTrees use AI?

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.

What about my privacy?

We take your privacy very seriously. Your workout data and personal information are used exclusively to improve your experience within the SkillTrees app, such as tailoring workout recommendations. We do not sell your data to third parties. Your trust is our top priority.
