Roadstr v0.4.10 is out ⚡🗺️
🛰️ GPS now works on de-Googled phones — GrapheneOS, /e/OS, LineageOS. No Play Services required, ever. We read the GNSS hardware directly, which also means zero location data ever touches Google — for everyone.
Privacy-first navigation, the way it should be and remember, always FuckGoogle.

• Long-distance walking/cycling routes (Boston→Miami on foot? go for it)
• Rich POI details on tap: hours, phone, website, accessibility
• Voice-volume slider, independent of your media
• Faster "locate me", plus imperial-unit fixes
Thanks to @nprofile…pgem for the extensive testing ✌️

My man! I tried to fix as many thing as possible from previous reports. But be careful with the avoid tolls feature. OsmAnd uses a weird way to discard tolls and paid highway, that I partially implemented in Roadstr but it has limitation, since I did not build a rendering engine in the app.

2026-07-18 21:35:48 CEST

🚗 Roadstr 0.4.8 is here!
You can now avoid highways and toll roads, while POIs show richer details like opening hours, accessibility, parking, EV charging, and Bitcoin/Lightning payments. We also added an in-app Wikipedia reader.
Under the hood: more reliable GPS, routing, zaps, and Nostr events, plus several security and privacy improvements.
Give it a try and let us know what you think! ⚡

Roadstr v0.4.6 (
ZTL (limited-traffic zones)
Fixed a bug that made ZTL detection silently fail since the feature shipped. The Overpass query used ["name"~"ZTL","i"] — the quoted "i" is a syntax error in Overpass QL (case-insensitive regex needs an unquoted ,i), so every ZTL fetch failed, on every mirror, from day one.
Rewrote ZTL detection to match how Italian zones are actually mapped. Italian ZTLs are tagged per-street (motor_vehicle=permit, access=no/destination, highway=pedestrian), not as named polygons — the old polygon-only query returned nothing even after the syntax fix. Detection is now proximity-based (≤12 m from a restricted way) in addition to the legacy polygon lookup, verified live against Ravenna's centro storico (251 restricted ways) and cross-checked against the ~350 Italian cities that do use the official boundary=limited_traffic_zone polygon tag.
Removed the overpass.osm.ch mirror. It turned out to be a Switzerland-only data extract that returned HTTP 200 with zero results for anywhere else — every dependent feature (ZTL, speed limits, speed cameras, POI search) silently read that as "nothing here." Replaced with two verified worldwide mirrors.
Verified live against 24 cities worldwide (12 European historic centres, 12 US cities/car-free towns) to check the new detection actually generalises rather than just fixing Italy. Works well anywhere OSM has restricted-access tagging; known gap where a town's equivalent has never been mapped by the local OSM community (e.g. Tangier Island, VA); intentionally does not flag toll-only zones (NYC congestion pricing, London ULEZ) as ZTL, since those don't restrict entry.
The warning banner now shows the correct local term instead of the Italian "ZTL" everywhere — "ZTL" in Italy and France (both use the same official term), "ZAC" in Portugal, a generic translated phrase elsewhere. Countries with no single official acronym (Spain, Germany, UK…) no longer get one invented for them.
Fixed the spoken ZTL warning, which previously had translations for only 9 of the app's 27 languages and silently fell back to English for the rest.
Navigation
Map no longer flips 180° mid-drive. A GPS multipath glitch could teleport a fix 20+ m backward with an inverted bearing, slipping past the existing distance-based filter. A direction reversal during active navigation is now trusted only after two consecutive GPS samples agree on it — a real U-turn confirms itself on the next fix, a glitch doesn't.
Voice no longer repeats the same instruction 3–4 times on approach to a manoeuvre. The same normalised instruction is now suppressed for 12 seconds at the single choke-point every announcement passes through.
Navigation cursor sits further down the screen, trading a bit of "behind you" for more visible road ahead.
Renamed the button on the pin/place-info panels from "Start navigation" (which actually opened a route preview) to "Show route preview" — "Start navigation" now only appears where navigation genuinely starts.
Security
A malicious relay could have redirected Lightning zaps to its own wallet. fetchLightningAddress trusted a relay's kind-0 profile event without checking its id hash, signature, or that the pubkey matched the person being zapped — fixed by verifying every profile event the same way road events already were.
Logging out no longer destroys local data. It previously called deleteAll() on secure storage, wiping the encrypted-settings key along with it — undecryptable on next launch, silently taking favourites, history and routing/NWC config with it. Logout now removes only the 5 Nostr-identity keys.
One-time report/confirmation fetches (profile screen) now verify event signatures and enforce one-vote-per-identity, matching the live subscription's rules — previously trusted unverified relay data and allowed repeat votes.
Amber (NIP-55) event publishing now broadcasts to all configured relays instead of only the primary one, matching nsec-login behaviour.
NIP-44 decryption now enforces the exact padded length the spec prescribes, rejecting malformed payloads other implementations would also refuse.
Consolidated three duplicated event-verification implementations into one shared, tested helper.

Nah Bitcoin Twitter switched platform and it's now here on nostr. People like @nprofile…tf6v @nprofile…zj6n and many others have a lot of traction in this world. Not having them on there, means that Bitcoin isn't discussed as much.

🚗 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."

Hopefully it'll be a reliable app.
I started this out of spite of Google Maps, an app that I love. But I can't still be in a relationship with Google, it would be hypocritical of me. So I'll be doing my own Google maps https://blossom.primal.net/6b920282952db026ef86f6936b49ff0a874bf611dd16dd6edb886de49d087b9f.png

This is gold, thanks man. I am still working on the istructions, they still come either too early or they overlap with each other, i gotta think of a logic to impart to be more precise. But the 3km alert I did it on purpose. When traveling long distances on highways, IMO it makes sense to have an early alert and then another alert 250m beforehand.
The premature end is another thing that I'm testing. This morning results were promising, but I only tested on a 5km city trip.
The annoying bug of starting on x road should be already fixed, but further testing is needed.
Great feedback overall, I'm gonna work on those improvements. Thanks again!

OSM doesn't respond to the calls of tolls roads, but I found another way. I'll test it before deploying.
Thanks mate!

2026-07-08 09:21:35 CEST

Great report, thank you!
I encountered these issues as well, I am working to fix them, especially the re-routing and and voice issue.
As for the auto dark, as of now there is a toggle to switch it on and off manually, I'll think of a better solution to give more control to the user.
Imperial will be implemented with tonight's update.
As for avoid tolls and such, afaik OSM doesn't manage those, so the user will have to switch to GraphHopper provider. There is a free API key with 500 "calls" or a paid plan.
I'll be working on those too as well, hoping to provide a free and open alternative.
Ps. Be careful, it's still a beta so drive safe!

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.

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 😂
