TerraTac / Android
Read the ground.
Make the call.
MGRS/UTM maps, live BLM/public-land status, GPS track-back, night vision, and G1/G7 ballistics with range rings — free with ads.
Field note: Phone GNSS is typically ~5–30 m. The compass can be affected by metal. Ballistics are model estimates — confirm zero with live fire. Land data is approximate — verify regulations.
