When I was on Android I was using SmarterTime [1]. It had a nice visualisation of the locations I’ve travelled throughout last day/week/month, etc.

But now that I’ve switched to iOS, I cannot find any similar application.

I want to know if there’s any similar service (preferably self hosted due to the sensitivity of the data). With a client app that could be installed on mobile devices.
