It is free, open source, and has no ads or mandatory account.</p> <p>This week we completed a shared experience and engineering pass across the full 22-tool catalog.</p> <h2> A calmer mobile interface </h2> <p>Every mini-app now uses the same compact surface system: clearer hierarchy, stronger contrast, visible focus states, consistent actions, and spacing designed for one-handed use. Tool pages also explain whether they work offline, process data locally, or need a download.</p> <h2> Less code on the first route </h2> <p>OCR and Password Vault no longer live inside the shared mini-app bundle. They are loaded only when their routes are opened. The shared mini-app JavaScript chunk dropped from about 48.6 KB to 43.4 KB before gzip.</p> <p>OCR now lets users choose English, Vietnamese, or Simplified Chinese and downloads only that trained-data pack on first use.</p> <h2> Safer Vault defaults </h2> <p>New web Vault entries use AES-GCM with per-entry salt and IV plus PBKDF2-HMAC-SHA-256 at 600,000 iterations. We added auto-lock, timed reveal, strict backup validation, bounded records, screenshot protection on Android, and safer clipboard handling.</p> <p>This is an internal hardening pass, not an independent security audit. We document the current threat model and limitations in the repository.</p> <h2> Tested on real hardware </h2> <p>The Android suite now traverses all 22 tools and verifies packaged permission and backup contracts. All four instrumentation tests passed on a physical RMX3941 device, alongside unit tests, lint, and production builds.</p> <p>Try the updated tools: <a href="https://hub.blissbiovn.com/en/tools" rel="noopener noreferrer">https://hub.blissbiovn.com/en/tools</a></p> <p>Source and implementation notes: <a href="https://github.com/shoyrulove-dev/PureHub/commit/3f64a51" rel="noopener noreferrer">https://github.com/shoyrulove-dev/PureHub/commit/3f64a51</a></p> <p>Which mini-app should receive the next deeper feature upgrade?</p> android opensource productivity privacy Frederic Ken Fri, 31 Jul 2026 12:50:36 +0000 https://dev.to/purehub/purehub-100-beta2-a-new-signed-build-for-community-testing-2157 https://dev.to/purehub/purehub-100-beta2-a-new-signed-build-for-community-testing-2157 <h1> PureHub 1.0.0-beta.2: A New Signed Build for Community Testing </h1> <p>We're excited to announce the release of <strong>PureHub 1.0.0-beta.2</strong>, a new signed Android build ready for community testing.
