Version 1.0 · 2010
How it all started
Mobi Calculator launched in 2010 as one of the first Android calculators with real expression editing and a working calculation history. At the time, that alone was enough to stand out.
It wasn’t trying to do everything. It was trying to do a few things right — and that turned out to matter a lot to people.
Millions of people, one simple app
Over the years, Mobi Calculator became a quiet daily habit for millions of users across the globe. No social features, no gamification. Just the app, open when you need it.
Many users have stuck with it for over a decade — installing it as the first app on every new phone.
A decade of loyalty
We never ran ads. We never pushed notifications. We just kept the app clean and let people get on with their day.
That kind of trust isn’t something you manufacture. It’s what happens when a tool just works, every single time.
Version 2.0 · coming soon
Version 2.0 — everything we’ve been saving up
For years we dreamed about features that no other calculator app had tried. Version 2.0 is where those ideas finally land — rebuilt interface, new functionality, and everything you already loved, kept intact.
The rule we set for ourselves: no new feature gets in the way of the familiar experience. Everything new either fits in seamlessly or can be turned off.
