Botple Calc
A full scientific calculator that works offline, installs like an app, and doesn't remember anything about you unless you ask it to.

Botple builds free, fast, and honest software for students — no subscriptions, no ads, and no account required just to get your work done.
Good study tools are too often locked behind subscriptions, cluttered with ads, or built assuming you always have a fast internet connection. That shouldn't be the bar for something as basic as a calculator or a reading app. Botple exists to lower that bar: building tools that work well, cost nothing, and respect your time and your data.

Botple started the way most useful things start — with a problem that kept getting in the way. It began with a student who kept running into the same small frustrations: calculator apps full of ads, tools that stopped working without Wi-Fi, software that seemed built for everyone except the person actually doing homework at 11pm. Botple Calc was the first fix, built and rebuilt based on what actually helped. Everything else here is being built the same way — slowly, carefully, and by actually using it.
Every tool Botple ships is free to use. That's a starting principle, not a limited-time offer.
No ad networks, no tracking pixels, nothing between you and your work.
Built around how students actually study, not around what's easiest to monetize.
Designed to work on modest devices and slower connections, not just the newest hardware.
Where it's technically possible, Botple tools aim to keep working without a live internet connection.
Where AI is used, like in MindSight, it's there to support understanding, not replace it — and we try to be upfront about when and how it's involved.
