About
SignalMap is your personal cellular signal logger and mapper. Track and visualize your cellular signal quality anywhere you go.
**Map Your Signal**
See your signal measurements on an interactive map with color-coded pins. Green means great coverage, yellow is acceptable, and red shows dead zones. Instantly identify the best and worst spots in your area.
**Measure Anywhere**
Take instant signal measurements that capture your carrier, radio technology (5G, LTE, 3G), connection quality, and exact GPS location. Add notes to remember specific details about each spot.
**Auto-Measure Mode**
Turn on automatic measurements and let SignalMap continuously record your signal quality as you move. Perfect for mapping coverage during drives or walks.
**Detailed Statistics**
See your average signal quality, best and worst spots, breakdowns by carrier and radio type, and quality distribution charts. Understand your coverage patterns at a glance.
**Complete History**
Browse all your past measurements with full details. Search, filter, and manage your signal data with swipe-to-delete.
**100% Private**
All data is stored locally on your device. No servers, no cloud uploads, no crowdsourcing, no tracking. Your location and signal data never leaves your phone.
