Help & FAQ

No. You can log dives right away without signing up — everything saves locally on your phone.

Creating an account unlocks three things: automatic cloud backup, syncing across devices (iPad, second iPhone, etc.), and being able to recover your logbook if you ever lose your device. You can sign up any time from the Profile tab — we'll migrate your existing dives over.

Yes. Bloo is offline-first by design. You can log dives, add photos, view your logbook, and check the map with no signal. Everything syncs to the cloud automatically once you're back online.

Tap the + button in the middle of the tab bar. The wizard takes you through three steps: Where → The Dive → Capture. You can skip any field that doesn't apply — only the dive site, max depth and duration are required.

Two places:

• On your phone — a local database, so the app works fully offline. This is the source of truth.
• In the cloud — once you've signed up. This is what backs up your logbook and syncs it to your other devices.

If you haven't created an account yet, your dives only live on this phone. Sign up any time to back them up.

Yes, after you sign up. Sign in on your iPad or second iPhone with the same email and your full logbook will sync down.

Make sure you have an account first (Profile tab → Save my dives if you're still anonymous). Install Bloo on the new phone, sign in with the same email, and everything will sync over — dives, photos, trips, the lot.

Profile → Export My Data. You'll get two options:

• JSON — complete GDPR-compliant data dump.
• UDDF — Universal Dive Data Format. Works with Subsurface and most other dive log apps.

Both work offline.

Yes. Bloo imports UDDF files — the standard format Subsurface, MacDive, Shearwater Cloud and most other dive log apps can export — and FIT files from Garmin and Suunto, complete with depth profiles and gear. Open the file with Bloo (from Files, or any share sheet) and the import flow takes it from there. Paper logbooks have their own route: see Scanning a paper logbook.

Yes. Tap + and choose Scan logbook. Photograph a page with the built-in document scanner (it finds the page edges and straightens it), or pick pages you've already photographed. Bloo reads every dive it finds on each page and shows you one card per dive to check and correct before anything lands in your logbook.

Reading a page needs a connection. The photos stay on your phone until you tap Read.

Good enough that most dives need a correction or two, not a rewrite — and it's built so you never have to trust it blindly. Each page is read three times and anything the reads disagreed on is marked in amber with the reason, next to a crop of your own handwriting. Every field is editable in place.

What helps most: a flat page in good light, with no shadow or glare across the writing, and the whole page in the frame.

Every account gets ten pages included, for the life of the account. Bloo Pro (annual or monthly) removes the limit. If you run out mid-batch, the pages you've already read still land — the rest wait, ready to read the moment you upgrade.

To Google's Gemini model, which reads the handwriting and returns the dives. That's the only outside party, and it's named in the privacy policy.

Bloo keeps the page photo in your private storage with the import, so each dive can show the page it came from — you'll find it at the foot of the dive as Logbook page. It never appears among your dive photos, it's never used to train anything, and it's deleted with your account.

Yes. Profile → Import history → Undo on the scan removes the dives it created, along with the buddies and sightings that came with them. The page photos stay in your import archive, the same way an imported file's original does.

• Free: 6 photos per dive, no videos.
• Pro: 50 photos + 5 videos per dive.

Photos upload in the background after you save the dive. If you're offline, they'll queue and upload the next time you're online. On a dive card you'll see a small cloud badge with the count of photos still uploading — tap it to force a retry.

If a photo's still missing after a retry, report it as a bug with the dive date and we'll look into it.

Yes — the photo picker lets you choose from your camera roll or take a new photo. HEIC (iPhone) and JPEG are both supported.

• More media per dive: 50 photos + 5 videos (vs 6 photos free).
• Advanced stats & trends — year-by-year deep-dives, activity charts and depth histograms, with more Pro features on the way.

Bloo Pro is a yearly subscription with a 14-day free trial. The paywall in the app always shows the current price in your currency — and early adopters lock in founding-member pricing for as long as they stay subscribed.

iOS manages all subscriptions centrally:

• iPhone: Settings app → tap your name at the top → Subscriptions → Bloo Pro → Cancel Subscription.

Your Pro features stay active until the end of your current billing period.

Yes. After installing Bloo on the new device and signing in, the paywall has a Restore Purchases button. Apple will match your subscription to the new install automatically.

Your existing photos stay accessible — we never delete anything because you downgraded. You just won't be able to add new photos beyond the 6-per-dive free limit until you resubscribe.

Trips group your dives into collections — your Bali liveaboard, that Red Sea week. Create one from the Logbook's Trips segment with the + button, then add dives from the trip's detail screen.

Yes. Open the trip → Edit → Add Dives. You can pick from any of your unassigned dives.

Bloo comes with thousands of known dive sites worldwide (sourced from public data). If your site isn't there, you can add it yourself — open the Log Dive wizard, tap the site picker, search for the site name, and choose Add new. It'll appear on your map immediately.

Sites you add are shared into the global database (minus anything personal — just name + coordinates + country). Other divers in the same area benefit from your contribution.

Your actual dive logs at those sites are completely private to you.

Only you. Bloo doesn't have a social feed. Your dives, photos, and notes are private to your account, enforced server-side.

Yes. Photos and videos are stored in a private bucket (never public), accessed via short-lived signed URLs. All traffic is HTTPS. Your dive data is protected by row-level security — server-side access checks enforce that nobody can read your data but you.

Profile → Delete Account. This wipes all your dives, photos, trips, and profile data, across the cloud and this device. There's a two-step confirmation because it's permanent. Full GDPR compliance — nothing recoverable afterwards.

Yes — Profile → Export My Data → JSON gives you the complete GDPR-compliant dump.

This usually means you're offline or your network can't reach our servers. Check your connection and tap Try again. If that doesn't work and you're definitely online, report it as a bug and include what you were doing when it happened.

If you saw the celebration screen, the dive is saved locally. Check the logbook — it should be there. If it synced to another device and isn't here, pull down on the logbook to refresh.

If you're sure it's missing, report it as a bug with the approximate date and site.
