You need to have the Telegram app installed on your device.

There is almost always a live tracker of the ride location in there.

You can also use the app “Critical Maps” to locate the ride – but it is dependent on others activating it.

It is very rare that anyone runs Glympse any more.

FAQ

– this tracking stuff is pretty freaky. I don’t want people following me home

When you start sharing in either Telegram or Critical Maps, you set for how long you share your location for. After that it turns off. You can also manually disable it if you leave early.

– isn’t this making it easier for the police/TFL to monitor us?

Maybe a tiny bit easier. In reality though, TFL use a massive network of CCTV cameras to track our position and ‘clean up’ the traffic after we pass through. They have a much better idea of where we are than we do

– So having GPS on constantly and broadcasting your position, that’s got to be a battery killer right?

Yes, unfortunately so. The app does drain your battery if you’re broadcasting. Even if you can only broadcast for an hour or so, it still helps us keep together and be found though! Otherwise, carry a spare battery or a portable battery charger (handy for so many things, available for about £20) Also if you’re using a tracking app anyway to map your route, then also using telegram or critical maps probably won’t make too much difference to your battery.

– I just don’t like this way of doing it. Is there any other way of finding the mass?

Not with any accuracy.
