Many messengers feature a geolocation tag — much convenient than explaining it over the phone. In Telegram, you can share your location dynamically — the recipient can track your movement in real time. Moreover, you can share your location for 15 min, 1h, 8h, or cancel the sharing at all.
Sending geolocation is easy. Tap the attachment icon -> choose Geoposition -> a map with several options opens up:
• Send geoposition (your current location)
• Broadcast geoposition (in real time)
• Choose a location (regardless of your current position)
It looks like in comparison to other messengers, Telegram offers the best execution of a live geolocation feature.
