Are these calculator simulators free to use?
Yes. Every simulator on Calculory is free, runs in your browser, and does not require sign up. There are no usage limits and no watermarks on the result.
Are these simulators official Casio, Texas Instruments, or Sharp calculators?
No. These are independent educational simulators built by Calculory. They are not affiliated with, endorsed by, or sponsored by Casio, Texas Instruments, Sharp, or any other calculator manufacturer. The simulators recreate familiar workflows for practice and learning, not the exact firmware of any specific model.
Can I use a calculator simulator during an exam?
That depends on your exam policy. Most exam boards require an approved physical calculator and ban any device with internet access during testing. Use the simulator for revision, homework, and lecture practice, then switch to your approved physical model on exam day.
Do the simulators work on mobile and tablet?
Yes. Each simulator has a tap-friendly keypad on touchscreens, plus a fullscreen mode so the keys stay large on a small display. Desktop users can also drive the simulator with the keyboard for faster input.
Will more simulator models be added?
Yes. The simulator hub will expand with more scientific, graphing, and construction calculator workflows over time. Each one will appear on this page once it is published.
