Describe it
Type what you want in plain words — "a countdown to my exam with a big number."
Chaaga
Your idea. Your app. No code.
Anyone can build the app only they would think of.
Chaaga turns a plain-language idea into a real, working app — for your family, your field, your classroom or your shop. No engineers, no waiting, no permission.

How it works
2
AI builds it
Chaaga writes it and opens it a few seconds later. Nothing to install, nothing to set up.
3
Use it, tweak it, keep it
Ask for changes in the same chat — "make the button bigger", "add a reset". It stays on your phone for good, and you can share it.
What you can make
Real things people made in a few minutes. Each one started with a single sentence.
Split the Bill
Tip, tax and who owes what, in three taps.
Streaks
A habit grid that fills in as the month goes.
Dice Table
d4 through d20 with a shake-to-roll gesture.
Days Until
One giant number counting down to the thing.
Flashcards
Paste a list, get a swipeable study deck.
Tap Racer
A silly two-thumb race for two people, one phone.
Shift Pay
Log hours, see the paycheck before payday.
Plant Water
Six plants, six schedules, one nudge a day.

Questions
Is it free?+
No card and no account needed to start. Buy usage in the shop when you need more.
Do I need to know how to code?+
No. Describing what you want is enough. If you do read code, the editor is one tap away and every app is a web file you can rewrite by hand.
Where does my data live?+
On your device. Apps and whatever they store never leave the phone. The only thing sent out is the prompt you type, which goes to the AI gateway.
How many apps can I make?+
As many as you want. There's no cap on how many apps you keep on your phone — build a new one whenever an idea shows up.
