Small Android apps for the things you do every day.
PZee is an independent app studio. We build calm, fast apps that work offline and keep your data on your phone. One app is live today, and two more are on the way.
Routinic is live on Google Play. Invoxa and MathWorksheetPDF are in development.
Our apps
Open an app to see what it does, how it treats your data and how to get in touch.

MathWorksheetPDF
Math worksheets and test papers for teachers, ready to print in seconds.
Routinic, up close
Pick a habit, tick it off, watch the streak grow. Routinic is built so that the app never gets in the way of the habit.
How we build
Three rules we apply to every app before it ships.
Offline first
Our apps work without a connection, so they stay fast and reliable on a train, in a lift or on a weak signal.
Private by default
We ask for as little as we can. Routinic needs no account and keeps your habit data on your device.
Focused and calm
Each app does one job well, without nagging, clutter or constant pressure to upgrade.
How an app gets made
The same four steps every time, from first idea to the Play Store.
Spot a daily problem
We start with something people already do every day, like tracking habits, sending invoices or preparing a class test.
Design it small
We sketch the one or two screens that matter most, and leave out everything that does not help.
Build it natively
Native Android with Kotlin and Jetpack Compose, so apps feel smooth and use little battery.
Test, ship, listen
We release on Google Play, read your feedback and keep improving the app.
An independent studio, built by one developer.
PZee was founded by Waheed Khan, a senior Android developer with more than eight years of experience shipping production apps. He designs, builds and releases every PZee app himself, from the first sketch to the Play Store listing.
Day to day that means native Android with Kotlin and Jetpack Compose, clean architecture and a lot of care for small details. Because one person owns the whole app, feedback goes straight to the person who can act on it.
