🚗 Roadstr v0.4.5 is live — search, cameras, encrypted favorites & more 🔍 Search is now local-first Nominatim results biased toward your GPS, with direct OSM category search (pharmacy, gas station, brands). "Cinema" finds the one down the street, not halfway across the world. 📹 Speed cameras layer added OSM highway cameras shown on map, integrated with proximity alerts. Stays alongside Nostr community reports — never replaces them. 🅿️ Save your parking spot Local-only, never touches Nostr. Button to mark "I'm here" or long-press to correct it after you've walked away. 🔐 Encrypted favorites sync via Nostr (NIP-44) Export favorites as JSON, optionally password-protected. Cross-device sync via self-encrypted NIP-44 events — relays only see ciphertext. Implemented NIP-44 from scratch with full test coverage. 🎙️ Voice improvements Male voices for all languages (except French), 6-stage speed slider, smoother navigation camera. 🛡️ Security audit completed Removed dead deeplink intent-filter, replaced Russian Overpass mirror with Swiss one (no GPS coords to VK), verified no tracking/analytics, private keys stay secure. License clarified: GPL-3.0. ~120 lint warnings cleaned. Zero compromises on privacy. Roadstr 0.4.5 out now. All open-source.

New release v.0.4.3 ## v0.4.3 (12) ### 🚗 Navigation - **Speed limits actually work now.** The root cause: `annotations=maxspeed` is a Mapbox-only extension — vanilla OSRM (including the FOSSGIS server we use) never returned it. Speed limits now come from Overpass, with class-based inference (motorway/trunk/residential/living_street) for the many roads that have no explicit `maxspeed` tag, 3 rotating mirrors for reliability, and support in free-roam driving (not just active navigation). - **Recenter button** now pulls a fresh one-shot GPS fix instead of reusing the last stream sample, so it snaps to your *actual* current position. - **Compass/heading button** is a real toggle in both navigation and free-roam — free-roam heading-up mode now rotates the map with the magnetometer instead of doing nothing. - **Secondary instruction panel** (next-turn preview) enlarged ~100% — bigger icon, bigger text, easier to read at a glance. ### 🔊 Voice - Turn instructions and hazard/ZTL alerts no longer cut each other off mid-sentence. Maneuvers are priority (interrupt immediately); ambient alerts queue and wait their turn, keeping only the most recent one. - Fixed a race in audio ducking where a stale utterance could release focus meant for a new one, breaking the "duck other media" behavior. ### 🔒 Security - Nostr events are now cryptographically verified (event hash + BIP-340 signature) before being trusted — a malicious relay could previously fabricate road reports or confirmations under any pubkey. - One vote per identity per event confirmation (was previously unlimited/re-countable). - Local settings (favorites, search history) are now AES-256 encrypted at rest, key held in the Android Keystore. - `debugPrint` is silenced in release builds — no more street names/coordinates/TTS phrases in logcat. - Event comments capped at 500 chars to prevent relay-side payload abuse. ### 🎬 Onboarding - Welcome page now shows the real app logo and a privacy notice recommending a VPN (Mullvad, Bitcoin-payable) given that road reports propagate over Nostr. - nsec login page now shows the same security disclaimer as the profile screen. - Fixed the Kokoro voice download completion indicator — it was implemented but never actually triggered (listener was waiting on a stream event that never fires); now shows a white check on a green circle when the download finishes. - GrapheneOS guidance now mentions setting location permission to "Allow all the time," not just "while in use."

NEW RELEASE! roadstr.v.0.4.0.apk 🚀 First-launch onboarding New 4-page flow on first install: features showcase → Nostr identity → permissions → ready. Nostr login via Amber NIP-55 (recommended) or nsec key (stored in Android Keystore). Profile name and avatar are fetched from the relay immediately after login. Dedicated GrapheneOS guidance: grant Precise location (not Approximate) and "Allow always" — not just while in use — to keep GPS active in background. Optional Kokoro AI voice model download (82 MB) with live progress bar. Can be deferred to Settings → Navigation voice. Pages are freely swipeable left/right. Fully localised in all 27 supported languages. Existing users who had already accepted the disclaimer skip onboarding automatically. ⚠️ ZTL / restricted zone ahead warning Safety The app now checks whether an upcoming turn leads into a restricted traffic zone at the moment the instruction is announced — before the user enters. An orange banner and a spoken voice warning trigger at that point. One warning per step, no repeated alerts. Distinct from the existing red banner shown when already inside a ZTL. The two states never stack. Warning text is localised — spoken in the user's language at runtime. 🔄 Missed-turn rerouting Navigation After advancing to a new step, a 2.5-second guard timer verifies the user is actually approaching the next waypoint. If distance hasn't improved by 20 m and speed is above 3 km/h, a silent reroute triggers automatically. 🔊 TTS announcement improvements Navigation Urban steps now receive an immediate voice announcement right after a maneuver is completed, replacing the previous premature 220 m trigger. Announcement distances adapt to road type and current speed. TTS near-threshold (50 m) preserved on all road types. 📍 Cursor styles overhaul UI 7 selectable cursors rendered from SVG assets via flutter_svg: Arrow, Muscle Car, SUV, Compact, Vespa, Racing Moto, Bicycle. Settings replaced the icon grid with a dropdown with live icon preview. All icons point north (direction of travel); heading rotation applied at the marker level. 🌐 Localisation sweep i18n Event report categories, transport mode chips, navigation time labels, and weather descriptions are now fully localised across all 27 supported languages. 40 new ARB keys added covering all onboarding screen strings — titles, CTAs, body text, and error messages. Short UI strings (buttons, titles) fully translated in all 27 locales. Longer body texts fall back to English where professional translation is unavailable. 🔧 Other improvements Polish Preview panel (route start) now supports a drag-to-close gesture with spring-back animation, matching the Alternatives panel. Secondary nav instruction row now shows distance to next maneuver. Speed limit exceeded → red speedometer arc, text and border.

Tried the app in a major travel, works smooth as fuck. #dontrawdogyournsec

Just rawdogged my nsec into the login screen of the app I am building instead of using an extension or signer, just for fun. No extension, no webLN, just pure manual copy-paste action. It felt illegal typing it out, but the implementation works perfectly. Screens looks clean though 😂

Who controls your maps, controls your direction. Meet Roadstr, a completely vibecoded navigation app built directly on Nostr. No corporate bloat, no tracking, no Big Tech. Just pure vibes, protocol-level privacy, and the open road. Roadstr: the maps app you control. Curious to see what happens when decentralization meets vibecoding? Follow this profile to catch the first beta updates. #vibecoding #Roadstr
