About this app

Kalkulilo is a proof-of-concept for a gesture-based scientific calculator. Based on lightweight machine learning models for time series classification, it merges a powerful calculator, an intuitive interface and a super intelligent keyboard. Thanks to this, it becomes easy to input functions, constants or any variable you may have created. Simply draw the gesture over their corresponding keys and the app will predict the function or variable you want with a high degree of accuracy. Never lose your time looking for a button again!

This version provides the following features:

- 3 themes (classic, dark, and light);
- 3 output modes (basic, dimm, and colorize)
- 39 predefined functions;
- 14 basic operators;
- A fast solver written in native code;
- Trigonometric functions in degrees or radians;
- An intelligent keyboard to quickly input functions, constants and variables;
- Unlimited number of variables;
- Input history.
