Rock-solid collections and smarter offline maps. **Your routes are safe** Major hardening of local storage and cloud sync: collections can never be lost by sync glitches, deletes stick across all your devices, and if anything ever goes wrong the app now restores your routes automatically. **Better race-file imports** GPX files from ExpertGPS now import with proper track names, and shared course waypoints show up everywhere — on the map, in the lists, and editable with a tap. **Offline maps, your way** Downloads now follow a tight corridor along your route (way smaller), and you choose the detail level with real download sizes up front.

Minor update nothing huge :)

DirtOS launches. Same app, new name, plus a race organizer portal, hands-free push-to-talk voice comms!

PreRun 4.1 adds Group Ride Chat, smarter offline maps, and a new way to combine routes. **Group Ride Chat** Text your entire group ride from inside the app — no jumping to another app to say "stopped for fuel" or "washed out ahead." Presets for common messages, on-the-fly voice-to-text dictation for gloved hands, and optional audio announcement of incoming messages so the driver never has to look at the screen. Works alongside the existing live location map so you can see and hear your crew. **Merge Items** Combine two or more routes, tracks, or runs into a single new item. Tap once, pick the items in the order you want them, and you get a new runnable file with all the tracks and waypoints in one place — perfect for stitching multi-stage races together or joining recorded sections into a master route. **Smarter Offline Maps** Route downloads now follow the actual shape of your track in a 10-mile-wide corridor instead of a giant rectangle covering empty desert. Detail level auto-scales to fit within Mapbox's storage limits so long routes actually download. A new Storage page shows every downloaded map, its size, and its zoom range so you can see exactly what's on-device and free up space. And when you go offline mid-race, the map silently caps zoom to what's downloaded so it never goes white. **Accurate Distance Off-Route** Distance-to-next-waypoint now reflects the true distance from where you actually are — direct to the closest point on the route plus distance along it — instead of pretending you were already on the route. Plan a Baja pre-run from your garage and see honest mileage before you leave. **Cleaner Merges + Sharing** Merge Waypoints reworked to a single three-dot picker (no more hiding items and re-running to line things up). Shared route links now open in the app reliably from Chrome. Discover search drops a tappable map pin so you can see exactly where the result is before you commit. **Custom Icons That Stick** Imported PNG icons no longer disappear after app updates. Existing icons come back automatically on first launch of this version. Plus minor bug fixes and polish throughout. Try free. Go Pro for $49.99/year — 14-day free trial — to unlock follow mode, audio, Quick Keys, cloud sync, chat, exports, and more.

### What's New (v4.0) PreRun 4.0 is a massive feature release with major new features, a huge performance pass, and critical routing fixes. **Universal Go To** Tap any destination and get a route. Discover page with search: businesses, POIs, coordinates. Long-press anywhere on the map to save as a waypoint or navigate to it. Tap a group member's puck to Go To them. Automatic fuel-range gas stop insertion for routes that exceed your rig's range. **Photo Waypoints Overlay** Show My Photos toggle in Map Overlays. Every geotagged photo from your library appears on the map as a clustered pin. Tap to view. Automatically refreshes as you take new photos. **Weather Callouts + Radar (Pro)** Real-time NEXRAD weather radar overlay. Automatic audio callouts for destination forecast, severe alerts along your route, and precipitation warnings 20 miles ahead. All powered by the NWS. **Tour Mode** Enable Tour Mode and PreRun automatically announces nearby Wikipedia points of interest as you drive — historic sites, landmarks, geographic features. Zero effort, unlimited history and geography lessons on every road trip. **Global Stats Page** Total runs, distance, longest run, current streak, unique routes driven. All aggregated across every run in every collection. **Group Ride v4 — Persistence + Public Discovery** Your group ID persists across sessions so you don't have to share a new code every day. Set a friendly group name that everyone sees on join. Optional "Public" toggle lists your group in a discovery view so anyone nearby can join without a code. New Join screen with dropdowns for Public groups (sorted by distance), your Recent groups, and manual code entry. **OHV Trail Routing FIXED** Dirt bike / ATV / UTV trails on USFS/BLM/state land are now routable via Build Route. Previously the routing engine could only route on full-size 4x4 trails. This release fixes that for every OHV-only trail in the country. **Trail Overlay Tap Fix** Tap any trail to see its full length highlighted in red — no more "only 1/4 of the trail lights up." Fat-finger-friendly tap detection so you don't have to hit the exact pixel. **Baja-Scale Performance Pass** Everything from 3000-waypoint prerun routes to 100k-trackpoint logs is now handled without frame drops. GPS teleport glitches no longer freeze the app. Long recording sessions save without stalling the UI. **Follow-Camera Consistency** Chase Cam (double-tap Find Me) and the group ride "Follow Me" mode now use the exact same smooth camera behavior — adaptive frame rate for 10Hz Garmin pucks, compass-driven rotation when stationary, puck-bearing switching so the arrow always matches the camera direction. **Fixes + polish** - Long-press map during a Run now drops a pending waypoint (same as Quick Keys during a Run) - Track log save moved off the main thread so long runs save instantly - Weather / Tour Mode toggle now cascade off with Audio Callouts (master switch) - Better landscape support in follow mode (location puck no longer disappears on rotation) - TTS survives phone calls (audio session interruption handling) Try free. Go Pro for $49.99/year — 14-day free trial — to unlock follow mode, audio, Quick Keys, cloud sync, and exports.

PreRun 3.0 is our biggest update yet. Here's what's new since v2.0: **Cloud Sync (Pro)** Routes, collections, and settings now sync across every device you sign in if you choose. Edit a route on your phone, see it on your tablet. Real-time updates, soft delete with a trash list, item-level merge so two devices editing at once don't lose work. **Find Me Chase Cam** Double-tap the Find Me button to enter a heading-up follow camera. No navigation, no audio, no run circles — just you and the map, with the camera rotating to match your direction of travel. Tap once to exit. **Configurable Run Display** Three customizable circles in the bottom of follow mode. Pick what each shows: speed, ETA to finish, time to next waypoint, elapsed, distance to next, waypoint arrow, or lap count. Size is configurable. **Rally Pacenote Mode** Optional 1–6 turn severity scale (classic rally pacenote style) instead of the standard 5-level severity. Pacenotes spoken with your route. **Countdown Distance Callouts** Speak distance numbers as you approach waypoints — "500, 400, 300, 200, 100, here" — fully configurable distance list. **28-Language Audio** On-device ML Kit translation means turn-by-turn audio callouts can be spoken in any of 28 supported languages, fully offline. Pick the language and speech rate in Voice Settings. **Off-Course Warnings + Speed Zones** Automatic alerts when you drift more than your configured distance from the route. Configurable speed zone keywords (e.g., "SZ START" / "SZ END") with optional audio over-speed alerts. **Lap Counting in Loop Mode** Loop Mode now counts and announces laps automatically. **Flyover Preview** Preview any saved route as a 3D camera animation before you drive it — no need to start follow mode. **Quick Keys Improvements** 52-icon library covering Terrain, Elevation, Man-made, Navigation, Race, Safety, and General categories — from silt beds and whoops to checkpoints, speed zones, danger triple-bangs, and Y-junction forks. Plus an unsaved-changes warning so you don't lose your config, audio ducking so callouts pause your music briefly, and fork detection for branching routes. **Settings, Reorganized** Settings is now broken into focused sub-pages: General, Trail Overlay, Route Preferences, Navigation, Map Display, Turn Detection, Flyover. Easier to find what you want. **Region Download** Polygon-drawing region selection, automatic zoom to fit, route overlays drawn on top so you can see what you're downloading.
