Spotwire

Tells the people who are waiting that somebody arrived.

Name a place once, home, the hostel, the office, and when the person arrives there, everyone who should know gets a single message with the time. The person waiting does not need the app, or even a smartphone: alerts arrive as a plain text message on Pakistani numbers, over WhatsApp, or inside the app. Spotwire is deliberately not a tracker: it reports arrivals at places both sides agreed on rather than a dot on a map, keeps an honest timeline that shows its own gaps instead of guessing, and leaves live location off by default behind its own separate permission.

Distributed as an Android app.
