PoolCheck answers the question every pool family asks: who's at the pool? Whether you're packing up the kids or wondering if your friends are already there, PoolCheck gives you a live view of your pool community. Auto or manual — your choice. Turn on auto check-in and PoolCheck handles your arrivals and departures via geofence. Prefer not to share precise location? Manual mode works too — tap to check in when you arrive, tap to leave. Either way, your friends see who's at the pool. Plan ahead. Headed over later? Plan to Go lets friends know you're on your way so they can join you. Bring the family. Add family members and guests to your check-ins. Family members who join PoolCheck later link automatically by phone number. Friend-gated privacy. Your check-ins are only visible to your approved friends. Mute notifications from specific friends, or hide your activity from anyone on your list without unfriending them. Discover pools nearby. When adding a pool, PoolCheck shows pools already on the app within walking distance. Tap to join instantly — no codes, no owner approval. Delete your account anytime. Your data goes with it. Features: • Real-time friend activity feed • Auto check-in via geofencing OR manual tap-to-check-in • Plan to Go — share your arrival time • Family and guest tracking • Friend-gated privacy with mute and hide PoolCheck is free.
