For the people who starred this repo

If Android was what you were waiting for — it's here. Same app, same features, same zero-network architecture, same open-source code. Both stores now:

• Google Play — Android 7+
• App Store — iOS 12+

Same 3-tier Pro unlock across both: $3.99/mo, $29.99/yr, $149.99 lifetime. Free base app with 3 tools, the 1m-precision 4-digit MGRS grid, a free theme, and 3 radio-ready report templates.

What shipped in v3.3.2 (Android launch)

• First Android production release — worldwide distribution
• Map zoom +/– controls and one-tap Recenter-on-Me
• Puppeteer-based screenshot compositor (phone, 7" tablet, 10" tablet frames)
• Mesh node card polish (degree symbol, altitude guard)
• Local Gradle + fastlane build pipeline (off EAS)

See the v3.3.2 release notes for the full changelog.

How you can help

The biggest lever for a new Android app is early ratings + reviews. If you install and it works for you:

1. Rate it on the Play Store listing
2. Leave a short review — especially if you can speak to the zero-network architecture or the MGRS accuracy
3. Tell another land-nav nerd (r/meshtastic, r/searchandrescue, SAR teams, hunting/ham radio folks)

Without ratings on the Play Store the app is effectively invisible for generic keyword searches — competitors with years of reviews outrank a new app instantly.

Architecture reminder (what you're actually installing)

• Zero network calls, zero analytics, zero crash reporting
• GPS coordinates live in memory only — never persisted, never transmitted
• MGRS conversions use the DMA TM 8358.1 algorithm
• Bearing/distance uses Vincenty on WGS84 (sub-millimeter ellipsoidal accuracy)
• Read the source, audit the math, fork it

What's next

• Full v3.5 roadmap in the README (camera-based target acquisition, encrypted mesh channels, Apple Watch, CoT for ATAK, route planning)
• Android 16 KB page-size rebuild coming before the next update
• Real Play Store analytics data will start flowing around Apr 26-27 (Google reports lag ~9 days)
