This update fixes several bugs, including a Weather Routing Worker lifecycle issue that could cause out-of-memory (OOM) errors during multi-model routing. It also improves boat and track alignment on the map and makes simulations, routing and replays smoother.

GPS navigation track recording. Start tracking during your trips, follow your track on the map, review navigation details, and export your tracks as GPX. Also improves live boat and track visibility on the map.

Added weather/performance projections on the main route, making it easier to compare the displayed route with optimized routings. Improved the Simulations screen with a more visible and accessible “New routing” button

Fixed WPOL polar file import on mobile: .wpol files can now be selected from the upload button. Fixed route playback speed display: the boat info bubble now stays consistent with the speed graph during sail/motor transitions.

Improved weather display reliability: time controls now remain available with cached weather data. Weather timeline consistency has been strengthened.

Multi-model routing: run and compare several weather models within one routing group. Clearer result display, per-model diagnostics, improved handling of partial routing results, important bug and performance fixes.

Fixed restoration of active MBTiles maps after restart. Selected offline overlays now remain visible more reliably when reopening the app.

Improved offline MBTiles chart management: imported charts now display automatically and can be enabled or disabled directly from the Offline Cache panel.

improved map performance and reduced GPU/battery usage with weather layers. Added and improved offline MBTiles map management. Various fixes and optimizations for smoother navigatio

Fix: app no longer freezes on splash screen when launched offline on iOS New: Copernicus ocean current models, Mediterranean (MEDSEA), Baltic Sea, NW European Shelf (ENWS)

fix Offline map cache map tiles are now cached automatically as you navigate. After going offline, the map remains visible for previously viewed areas. Fixed cold start in airplane mode on iOS and Android. Added a map tile cache purge button in settings.

• Fixed time slider desynchronization on long ECMWF forecasts : The time controller now correctly handles non-uniform time steps (3h + 6h) when viewing forecasts longer than 6 days. Previously, scrolling beyond the 144h boundary caused the timeline, route graph, and wind overlay to drift apart. • Fixed ECMWF Z06/Z18 time slider offset : The "Go to Now" button and time index calculations now use binary search instead of linear interpolation, properly handling merged ECMWF runs with mixed step intervals. • Uniform route naming : Auto and manual routes now consistently display in DD/MM HH:mm - MODEL ZRUN format.

• Better routing error messages: clear diagnostics for excessive wind, swell or insufficient GRIB data • Diagnostic counters to understand routing calculation limits • Improved ECMWF and Météo-France weather data reliability

• Fixed file download and sharing on iOS and Android (GPX routes, polar files) • Exported files now open with the correct apps via native share sheet • Expanded polar catalog: +409 boats added (Fountaine Pajot, Lagoon, Nautitech, JPK, Hallberg-Rassy…) • Minor fixes and stability improvements

Fixed default routing form parameters: maximum apparent wind is now set to 17 knots to better match common sailing conditions.

• Manual GPS coordinate input for waypoints (DMS, decimal, paste support) • Fix: departure time now uses local time instead of UTC • Routing stops gracefully when GRIB forecast horizon is reached • Server improvement: GRIB download decoupled from main server

• GRIB microservices split — gribsrv split into grib-server + grib-downloader (#211) • ICON Global model added + experimental flags removed (#208/#209) • ICON-EU & ICON-D2 models added to frontend + API enum fix (#204) • ICON-D2 model backend support + ICON-EU fix (#201) Fixes • ICON-EU download — improved cycle detection + retry hardening (#199/#200) • ECMWF — merged oper + scda streams for full forecast range (#195/#198) • Routing — A* safety margin improvements + localStorage-first defaults (#190/#191)

• Significantly improved land detection: finer sampling along segments and restored recursive subdivision, to avoid cutting across headlands and narrow islands. • New "safety margin from land" setting in advanced options (0 to 3 NM), to tailor routing to your navigation style. • Major performance boost on land detection — high-precision calculations are now up to 4× faster.

Fixed routing with currents in coastal areas. The app no longer fails when current data doesn't cover the departure point.

Fixed automatic weather data updates. Existing users will now receive automatic weather updates when opening the app again.

Bug fixes: • Fixed app stuck on splash screen when server is unreachable or offline • Weather data (GRIB) is no longer deleted when losing network or toggling airplane mode • Fixed random "Boat polar error" during route calculation • Automatic weather data update is now enabled by default Improvements: • Better offline support: the app now loads correctly without internet connection • Weather data downloads can no longer overlap, preventing data corruption • Enhanced polar data validation before route calculation

Fix and One-tap weather routing from your GPS position. Get an optimized route instantly without manually setting waypoints.

Quick weather routing: long press → automatic routing from your GPS position • UI adapted to weather data type (wind/wave/current) • Ocean currents and high-resolution standard grid • Fixed apparent wind angle (AWA) calculation • Wave color palette • Routing and GRIB data stability fixes

Weather model adaptation (waves and currents) • The UI automatically adapts to the loaded GRIB model: navigation bar, weather bubble, and route chart display metrics matching the selected model type (wind, waves, or currents) • New apparent wind calculation (AWS/AWA) displayed in boat data • Fixed true wind angle (TWA) calculation with port/starboard sign • Ocean current data is now properly interpolated between frames
