Bloo is free to download and use — log unlimited dives, trips and maps at no cost. Optional Pro features for those who want them. Your dive life, beautifully kept.
Your dives, beautifully archived.
Bloo is a dive journal for divers who care about the memory as much as the log. Built offline-first so you can log a dive at the boat, on the plane, or on the drive home — then sync the moment you're back on Wi-Fi.
BUILT FOR THE POST-DIVE RITUAL
• Log a dive in under 60 seconds: site, depth, time, conditions, rating.
• Metric or imperial — set it once, change it any time.
• Attach photos from your camera roll as first-class memories, not afterthought attachments.
• Search a global database of dive sites — or drop a pin on a new one.
• Works fully offline. No spinner. No "try again later."
• Track your certifications by agency and level, from Open Water to instructor.
SWITCHING FROM ANOTHER APP?
• Bring your whole dive history with you. Import from Subsurface, Shearwater and other apps via UDDF — your dives, sites, buddies and gear, all in one place.
• Tap a .uddf file in Files, Mail or AirDrop to open it straight in Bloo.
• Then bring each dive back to life: add photos, tag a location, and write down what you remember.
EVERY DIVE IS A STORY
• Group dives into trips so every adventure lives as one memory.
• Revisit any dive with the photos, notes, and conditions you captured that day.
• See your depth and temperature profile for computer-logged dives — scrub through to relive any moment.
• Lifetime stats: bottom time, depth records, countries dived, dives per year.
DIVE WITH FRIENDS
• Add the buddies you dived with — and tag your instructor or divemaster.
• Tap through to anyone's profile to see every dive you've shared together.
• Call, message, or email a buddy in a tap.
SEE EVERYWHERE YOU'VE BEEN
An interactive world map pins every site you've dived. Zoom in on a region and replay the trip.
BLOO PRO
The free tier is a full logbook — not a trial, not a teaser. Most divers will never need more. Bloo Pro unlocks:
• 50 photos per dive (up from 6)
• Videos on every dive (up to 5)
• Year-by-year stats — compare any year, any depth
• Buddy Wrapped — a beautiful, shareable recap of every dive you've shared with a buddy
YOUR DATA IS YOURS
Bring it in and take it out, anytime — import or export your entire logbook as JSON or UDDF, the open dive-log format your past and future software will still read. Private-only media storage with signed-URL access.
Log your first dive tonight — or bring a lifetime of them with you. Your future self will thank you.

I’ve tried many different apps and been frustrated by all of them. This one is smooth, allows me to keep track of my important info for FREE and keeps everything organized. Finally. Also a neat map showing all the places I’ve dived in the world. Easy edit feature
Developer Response
Thanks so much for the lovely review, Brooklybones! What you've described is exactly what I set out to build: a home for our dives that we can be proud of, and that is incredibly simple to keep up to date.Hearing it's finally the one that clicked for you, after all the others, means a lot.There's plenty more coming, too — the next update's a big one, with a proper rework of how you keep track of your dive buddies. I think you'll like it.Hope you continue enjoying it — happy diving! 🤿
Great dive log
JazzAnonymous
I’ve been searching for a quality dive log that doesn’t look and feel dated and this one does it! Looking forward to future updates.
Developer Response
Thanks so much for taking the time to review, JazzAnonymous, this genuinely made my day. “Doesn’t look and feel dated” is exactly what I was going for. There’s loads more coming including imperial units, local date/time formats, Apple sign-in, better dive site search, UDDF uploads and dive computer integrations. Keep diving and let me know if anything’s missing!
Bring your whole dive history home.
Importing has arrived. Move your logbook into Bloo from your old dive app — your dives, sites, buddies and gear, all in one place.
• Import your dives from a UDDF export (Subsurface, Shearwater and more), or just tap a .uddf file in Files, Mail or AirDrop to open it straight in Bloo.
• Bring them to life — after an import, Bloo helps you fill the gaps on each dive: add photos, tag a location, or jot down what you remember.
• Dive profiles — see your depth and temperature over the course of a dive, and scrub through to relive any moment.
• Plus polish and fixes throughout.
Every dive you've ever logged, finally in your pocket. Happy diving.
