TrailRelay 0.4.0

TrailRelay 0.4.0

This release improves map usability and trail context.

• Heading Up corrects compass readings to true north, filters small heading jitter, and uses reliable GPS course while moving. A saved Heading offset supports angled phone mounts without changing GPS course.
• GPS handling rejects stale, duplicate, and implausible fixes. Uncertain fixes can still show your reported location and accuracy circle without steering the follow camera.
• Selected trails show approximate distance from the route and neutral along-route distances to endpoints A and B. Disconnected GPX segments do not imply a connecting route, loop routes share an A/B marker, and your location indicator is never snapped to the trail.
• Zoom buttons, clearer map controls, and refined trail details improve map use. Camera zoom stops at 16 to avoid excessive enlargement beyond the USGS imagery's available detail.
• Map-source failures use a small status indicator with an explanation and retry action, keeping downloaded maps usable without a large error banner.
• The optional Show offline coverage setting displays a grid for the selected Aerial, Hybrid, or Topo mode. Completed packages have filled squares; incomplete packages have dashed outlines showing requested coverage, not confirmed downloaded tiles.
• Saved-route geometry caching and background overlay preparation reduce repeated GPX parsing and map preparation during route loading. Original GPX files remain canonical, and invalid derived cache entries are rebuilt.

Android 8.0 (API 26) or newer. No account or user API key is required. Offline maps cover only the downloaded area and zooms 12–16; download each map mode you need and check it without networking before heading out.

Updates from 0.3.0 use the same application ID and signing identity. Install as an update to retain saved trails and offline packages; uninstalling or clearing app data erases them.

TrailRelay 0.3.0

TrailRelay 0.3.0

This release adds Field Navigation Basics and Map Layers & Cartography.

• Choose North Up or Heading Up, with improved follow, manual pan, and recenter behavior.
• See GPS speed in mph on the map, with unavailable or stale readings handled more reliably.
• Use Open in Maps to send either trail endpoint to an installed map app.
• Switch between USGS Aerial, Hybrid, and Topo maps. Your map choice persists across launches.
• Download Aerial, Hybrid, and Topo packages independently for the same trail, with offline status matched to the selected map mode.
• New offline packages follow a trail corridor with surrounding context instead of downloading the entire route bounding box. Existing aerial packages remain recognized.
• Manage map packages by mode in Downloads & Storage, with clearer status and removal feedback while keeping route files separate.
• Enjoy smoother map-control placement around the selected-trail sheet.
• Recover missing or unreadable Community GPX files more reliably while preferring valid local files, with fixes for route cleanup and navigation edge cases.

Android 8.0 (API 26) or newer. No account or user API key is required. Offline maps cover only the downloaded area and zooms 12–16; download each map mode you need and check it without networking before heading out.

TrailRelay 0.2.0

TrailRelay 0.2.0

TrailRelay now opens on a map that shows saved trails. Select a route from the map or My Trails to focus its geometry and open a compact details sheet. Taps where routes overlap open a chooser.

• Preview Community routes on the map before saving them. Saved and imported GPX routes open from local storage.
• Browse Community with a compact search and filter row; full filters open in a bottom sheet.
• Use the Explore sheet to reach My Trails, Community, Downloads & Storage, Import GPX, and Settings.
• Manage route GPX files and aerial map packages separately in Downloads & Storage. View available size information and live download progress; pause, resume, or remove aerial packages without removing routes, and remove routes without removing aerial packages.
• See clearer route and aerial status in Trail Detail and across the app, with a consistent Material 3 layout.
• Use the new Keep screen awake setting while TrailRelay is in use.

Android 8.0 (API 26) or newer. No account or user API key is required. Offline aerial coverage remains limited to the downloaded area and zoom range; check saved routes and imagery without network access before heading out.

TrailRelay 0.1.0

TrailRelay 0.1.0 — early alpha

Release candidate notes; an APK has not been published as part of this milestone.

• USGS / The National Map aerial imagery.
• Foreground GPS location, follow, and recenter.
• GPX import and a persistent local My Trails library.
• Community trail catalog with local search and filtering.
• Community GPX downloads saved for offline use.
• Offline aerial imagery around trails, with download progress, pause/resume, and removal.

Android 8.0 (API 26) or newer. No account or user API key required.

This is an early alpha. Downloaded imagery covers a padded trail bounding box at zooms 12–16; coverage outside that area or zoom range may require networking. Check downloaded trails and imagery with networking disabled before heading out. Keep another navigation option available.
