fluenStudio
An independent app studio from Poland

Apps that turn learning
into a daily habit.

We build mobile apps for learning: short lessons, instant feedback and progress you can see. Simple to start, fair to use, careful with your data.

Our apps

Each app teaches one thing and does it well. One is almost here, the next is still under wraps.

Clefly

In testing

Learn piano from zero to reading sheet music.

  • Clefly listens as you play a real piano, or use the on-screen keyboard.
  • Short lessons, falling notes and songs at your own pace.
  • Turn songs into sheet music and drill the notes you miss.
Android 6 languages Free · optional Pro Coming soon to Google Play

How we build

fluen is a small studio run by one developer. A few rules shape every app we release.

Learn by doing

Short lessons and practice from the first minute, with feedback right after every answer.

A habit, not a chore

Daily goals, streaks and visible progress that make you want to come back tomorrow.

Privacy first

We collect only what an app needs, keep it on servers in the EU and never sell it. You can delete your account at any time.

Fair and open to all

A free version to start, clear prices for extras and apps translated into many languages.
