PhoneTrack SMS

Location sharing that respects your privacy and your data plan. This phone track app (PhoneTrack SMS) responds to text message requests with your GPS coordinates — no internet required, no account needed, no data used. It focuses on one thing and keeps it simple. A trusted contact texts your keyword and the phone texts back a location and an OpenStreetMap link. Need regular check-ins? Subscribe for periodic updates that include how far and which direction you've moved. The sender doesn't even need the app installed. New requests are held in a PENDING state until you decide: APPROVED numbers always get a reply, BLOCKED numbers are quietly ignored. You don't have to think about it until you want to. Features: * One-shot location request: reply with GPS fix + OpenStreetMap link * Subscriptions: periodic updates with heading and distance delta (e.g. ⇐314m) * Approval gate: PENDING → APPROVED / BLOCKED * Zero internet permission — SMS only, always * No account, no cloud, no tracking * Android 8.0 (API 26) and later
