[APP][OS][10.0+] Ambient Calculator - World's Lightest Open-Source AI & OCR Math Tool
Hey everyone,
I wanted to share Ambient Calculator, a 100% open-source, ad-free math tool built completely with Kotlin and Material 3 for Android phones, tablets, and foldables.
If you are tired of bulky calculator apps loaded with trackers, this is designed to be the exact opposite.
Why try it?
- Incredibly Lightweight: The Minimal Edition is only 1.8MB, beating OpenCalc (~2.2MB) and Fossify (~3MB).
- Offline AI OCR: Scan complex math problems to instantly get results 100% offline.
- Privacy First: Zero ads, zero tracking, and absolutely no permissions required for the minimal version.
- Beautiful UI: Full support for Material You dynamic theming, AMOLED dark mode, and dual-panel tablet layouts.
- Extra Features: Includes a handwriting-to-math preview, scientific mode, history, and a quick settings tile.
The project is licensed under the MIT License. I would love to get your feedback on the UI layout, OCR speeds, or any features you think are missing!
