Reef: Scuba Diving Logbook

The cleanest scuba diving logbook for British divers. From Scapa Flow to the Red Sea - log dives offline, track stats, attach photos, find your buddy. No subscription.

Every dive deserves a beautiful record.

Reef is the simplest, cleanest scuba diving logbook for British divers — built for recreational divers who want their dive history to look as good as it felt underwater. Whether you're a BSAC club diver logging shore dives in Cornwall, a PADI holiday diver headed to the Red Sea, or a tech diver running mixed gas on the Scapa Flow wrecks, Reef is the offline-first logbook in your pocket.

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 dive sites — from Scapa Flow to the Farne Islands, from the Manacles in Cornwall to Plymouth Sound, from Stoney Cove and Capernwray training quarries to the Red Sea, Maldives, Indonesia and the Philippines.

TRACK YOUR STATS Total dives, deepest dive, longest bottom time and top dive sites by count. Watch your logbook grow with every trip — every BSAC progression dive, every PADI specialty, every wreck weekend.

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 — your club mates, your instructor, the divers you met on the boat.

DIVE SITES & MAP Pin exactly where you dived on a map. Open your dive map any time to see every logged site across the world — your personal underwater atlas, from British wrecks to Red Sea reefs.

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, drysuit or mask is due for a service before it becomes a problem.

CERTIFICATIONS Store all your dive certifications in one place — BSAC Ocean Diver, Sports Diver, Dive Leader, Advanced Diver and First Class Diver grades, plus your PADI, SSI, NAUI, CMAS and RAID cards. 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 BSAC, PADI, SSI, NAUI, CMAS, SAA, RAID and all major certification agencies.
