Small Android apps with no ads, no tracking, and open-source code.
I build each one to replace an app on my own phone. They work offline, ask only for the permissions they need, and every line of code is on GitHub.
Type in Manglish and get Malayalam, or switch to English with one key.
Many Manglish keyboards show ads or need the internet. Ezhuthola has no permissions at all, not even internet, so your typing can’t leave your phone.
A retro calculator with a dark unibody design and a yellow glow. Live results as you type, full history, and a unit converter built in.
Declares no permissions at all, not even internet. It can’t send anything anywhere.
Alarms you can actually stop when you’re half asleep. Hold to snooze or dismiss, or chase the moon across the screen. Plus home screen widgets, hand-drawn.
No tiny swipe targets. You hold a big button to snooze or dismiss, so you can’t hit the wrong one half asleep.
A simple volume booster. Make quiet videos, calls and speakers louder, with one big button and a Quick Settings tile.
No ads and no internet permission. It uses Android’s own loudness effect, so nothing is recorded or sent anywhere.
Rich text notes, to-do lists and drawings, with app lock and backups to one file. No internet permission.
Your existing calendars, plus private events behind a fingerprint lock.

Every Numio app replaces something I used every day and wanted to be better. If it isn’t good enough for me, it doesn’t ship.
No ads, no analytics, no accounts. The apps work offline and ask only for the permissions they need. Read the privacy page.
Every line of code is on GitHub under GPL-3.0. Read it, build it yourself, or send a fix.
These apps are built with AI assistance. All code is open on GitHub, tested on my own phone, and licensed under GPL-3.0.
