PureHub

PureHub is a multifunctional open source toolbox！

Small, practical utilities for focus, measurement, scanning, documents, privacy, audio, and personal finance. 26 private-first mini apps. Free to use. Core mini-apps remain ad-free. No mandatory account. Open source.

PureHub is an offline-first utility collection for Android and the web. Instead of installing many single-purpose apps filled with advertising and tracking, you get 26 practical mini-app experiences, including the community hub, in a consistent interface.

Typical uses include scanning or creating a QR code, running a Pomodoro session, extracting text from an image, converting units, checking a level or compass, splitting a bill, tracking expenses, and following a guided breathing exercise.

PureHub is currently beta software. The web app is available now, and signed Android preview builds are published through GitHub Releases.

The flagship lineup now includes the Zen tools, QR Studio, the OCR + PDF Document Suite, Speaker Cleaner, the private Finance Suite, and the Compass + Level + Sound Sensor Suite.

Zen Habit, Zen Pomodoro, and Zen Breath now share a complete Zen Suite experience on web and Android. Pomodoro includes quick/custom focus sessions, private weekly rhythm tracking, and local soundscapes; Breath includes timed goals, accessible motion, optional cues, and private completion history.
