PureHub beta.19: a better Bubble Level, honest install metrics, and offline builds
PureHub beta.19 continues our goal: 22 useful Android and web tools that are free, ad-free, privacy-first, and open source.
What changed
🫧 Bubble Level becomes a flagship tool
The level now includes Surface, Edge X, and Edge Y modes; adjustable tolerance; zero calibration; stable-position feedback; vibration; and clear accuracy guidance. Sensor readings stay on-device.
📊 Honest growth analytics
An APK download is not the same as an install. The dashboard now reports APK download clicks, accepted PWA installs, standalone PWA opens, and completed useful results separately.
🛡️ Standard and F-Droid-ready builds
The release includes signed per-ABI APKs plus a fully offline F-Droid flavor using ZXing and Tesseract without ML Kit, Play Services, Firebase, ads, analytics, or trackers.
🎬 Reproducible demos
Three new short demos for Bubble Level, QR safety, and OCR-to-searchable-PDF were generated from the current interface and scheduled on YouTube.
