Description
Every dive deserves a beautiful record.
Reef is the simplest, cleanest scuba diving logbook for iOS — built for recreational divers who want their dive history to look as good as it felt underwater.
LOG YOUR DIVES
Depth, duration, water temp, visibility, air consumption, tank pressure, dive site and notes. Tap in at the surface while it's fresh. Works fully offline on liveaboards and remote reefs.
TRACK YOUR STATS
Total dives, deepest dive, longest bottom time and top dive sites by count. Watch your logbook grow with every trip.
ATTACH PHOTOS
Turn each dive entry into a visual story. Add photos straight from your camera roll to any log entry.
DIVE BUDDY
Log who you dived with. Build your buddy history across every trip and location.
DIVE SITES & MAP
Pin exactly where you dived on a map. Open your dive map anytime to see every logged site across the world — your personal underwater atlas.
GEAR LOCKER
Store all your dive equipment in one place. Track service intervals by dive count and time — Reef tells you when your BCD, regulator, wetsuit or mask is due for a service before it becomes a problem.
CERTIFICATIONS
Store all your dive certifications in one place. See at a glance which are valid, expiring soon or expired — always ready to show at the dive centre.
No social network. No subscription required to log dives. Just a beautiful, private logbook — always in your pocket.
Compatible with PADI, SSI, NAUI, CMAS and all major certification agencies.
