PinMe ! Because your location is important !
PinMe allows you to create a private personal location history, with no 3rd party holding the data.
This is a crazy-important feature. 
While there are excellent tracking apps for running, hiking, vehicles or holidays, they typically involve someone else holding your data.
PinMe provides 100% consented and user-controlled location logs, no service provider hosting or 2nd party involvement.

PinMe allows you to prove your location if needed, to defend against claims or just to keep a personal record.
Ideal for carers, gig workers, self-employed service providers, anyone who needs to record their location for any purpose.
PinMe offers 3 modes : SmartPlaces (geofences) for hands-free visit records, or ad-hoc location logs, or scheduled interval logs.

All data is local on-device, so don't lose it! We don't ever get a copy.
Implement off-device backup storage by using a Seq log store, or periodic exports to GPX or CSV.

You are never tracked by the app, and your data never leaves the device unless you specifically export it as a GPX or CSV file, for your own records or for sharing, or you configure a backup Seq log store.
Perfect for self-hosters managing their own data with Seq.

Built in Swift for native features and to minimise load on your phone’s battery.

NB : iOS built-in features might suspend background logging in certain cases (low battery, device asleep).This is unavoidable and not a bug.
