Family-Friendly Self-Hosted Location-Sharing Replacement for Apple Find My and Google Maps Timeline That a Non-Technical Spouse Will Actually Use
Privacy-conscious families want to keep 'where is everyone right now' working without giving Apple or Google a permanent map of the household. OwnTracks and Traccar exist but ship a sysadmin-grade UX that won't survive a real family rollout — config files, no decent iOS background-reliability, no friendly group management. The opportunity is a polished self-hostable app with a one-tap install on iOS and Android, a normal map view, geofence notifications, and family-grade permissions.
iOS background location is the entire ballgame here, and it's a quagmire — Apple kills your app's location updates on the slightest pretext. Build on top of significant-change + region monitoring + iBeacon for indoor anchors rather than continuous high-accuracy GPS, and accept that you'll lose some fidelity for massive battery and reliability wins. Solve that and you've already beaten OwnTracks where it has bled for a decade.

Every self-hosted location app is configurable and reliable but UX-hostile, and every UX-friendly option is owned by Apple or Google. There's a clear product gap: 'Find My' polish on top of an OwnTracks-style backend the family controls.
