Why Mica exists
My learning was split
across too many places.
Lessons had one thread, apps another and real conversations went wherever they liked. None of them remembered the exact thing I had struggled with.
So I built one course that uses yesterday's answers to choose today's practice — and keeps it pointed at the conversations I actually have.
How I keep it honest
Use it. Check it.
Cut what doesn't help.
I make the product calls. Claude helps plan features and author Catalan practice; Codex builds and tests the app. The test is simple: does it make tomorrow morning's practice better?
- 01Use it every day.
I hit the same annoyances any learner would.
- 02Check the numbers.
If a number looks wrong, I compare it with the actual learning history.
- 03Delete what doesn't teach.
Two working mini-games disappeared because they did not help the course.

One user so far.
Here's how hard it's used.
These are Ryan's own totals — one learner's daily use, counted by the app itself.
Enough reading

I use every morning.
