Solution. PinO is a native SwiftUI product for iPhone and Apple Watch. Flow is Mark, Walk, Back: one tap saves the place, the place stays on device, one tap brings you back. Watch uses WatchConnectivity. Privacy model is explicit: no account, no PinO central server, no ads; pins live on device; Always location only if proximity alerts are enabled; deleting the app removes on device data. App Store languages listed: English, Italian, French, Spanish, German. Not a full turn by turn navigator; it returns you to the pin. No subscription.
