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 catalogue of over 6,500 dive sites, or drop a pin on a new one. • Rename, merge, or remove any site you've added - including ones an import created for you. • Works fully offline. No spinner. No "try again later." • Track your certifications by agency and level, from Open Water to instructor. SCAN YOUR PAPER LOGBOOK • Photograph a page and Bloo reads the dives off it: date, site, depth, time, buddies, wildlife, notes. • Check every reading against the page before anything saves. Anything Bloo wasn't sure of is marked. • Your first 10 pages are free. Bloo Pro reads the rest. BRING YOUR DIVE HISTORY WITH YOU • Import straight from your dive computer: Garmin Descent and Suunto Ocean (.fit). • Or from another app: Subsurface, Shearwater, Oceanic+, MacDive and anything else that exports UDDF - your dives, sites, buddies and gear. • Pick several files at once. Bloo skips the dives it already has, so nothing lands twice. • Check every dive site before anything saves - link it, rename it, or keep it separate. • Tap a .fit or .uddf file in Files, Mail or AirDrop to open it straight in Bloo. 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. • Note what you saw: log the wildlife on any dive. • Scrub through your depth, temperature and tank-pressure profile on computer-logged dives. • 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. • Invite a buddy to connect. Once you both say yes, you see each other's dives. • Tag a buddy on a dive you did together and they can add it to their own logbook in a tap. • Keep any dive private with a single switch. Private dives never leave your logbook. • Buddy Wrapped: a beautiful, shareable recap of your history with each buddy. Free for everyone. SEE EVERYWHERE YOU'VE BEEN • An interactive world map pins every site you've dived. Zoom in on a region and replay the trip, or search to jump straight to a country or a named site. 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 • Your whole paper logbook, scanned (10 pages free) YOUR DATA IS YOURS 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, and bring your dive buddies too. Your future self will thank you. --- Bloo is fully functional without a subscription. Bloo Pro is an optional subscription, billed yearly or monthly; the yearly plan has a 14-day free trial.

Verdict
The clearest difference is in-app purchases: Waveform Surf at none against Bloo's 1. Waveform Surf also leads on device support (3 vs 1). Bloo's advantage is update cadence (weekly vs fortnightly). On price, ads and iOS requirement there is nothing between them.
