Three records, one app

Three things every diver has to keep track of.

Most dive apps log the dive and stop there. Your service stickers and your cert cards end up in a drawer at home, which is no help at all on a dock in Bali.

Dives

Depth, time, temperature, site, buddy, kit and notes. Entry is quick, and you can carry details across from your last dive if you want to. Photos attach to the dive and get copied in, so they stay with the record.

Gear

Service intervals in months or in dives, whichever falls due first. Log what the shop did and what it cost, photograph each item, record what you paid, then produce the gear list your insurer asks for.

Certification cards

Agency, course, number, date and instructor, with a photo of the card itself. When a dive centre asks for your number and you have no signal, it is right there in your pocket.

Built on diver feedback

Built around what divers told us.

Logbuoy came out of feedback from real divers about real problems with the apps they already use. Most of it had nothing to do with missing features. It was about logbooks that vanish, and logbooks you cannot get your dives back out of.

Your dives stay put

Your logbook is a plain database file sitting on your phone. Logbuoy keeps dated copies of it, and you can restore any of them yourself from inside the app.

Bring the logbook you already have

Import UDDF or CSV, including files other people's software wrote. Messy column names, imperial units and older UDDF all read fine, and your depth profiles come across with the dives.

Get your dives back out

Export the whole logbook as UDDF or CSV, the formats other dive software reads. Everything comes out, right down to the profiles.

Service intervals that count dives

A regulator due every twelve months or every hundred dives is due on whichever comes first. Logbuoy tracks both, and sorts your gear so the thing that needs attention sits at the top.

The gear list an insurer asks for

One tap turns your kit list, serial numbers, photos, service history and purchase prices into a PDF. If a bag goes missing or a case floods, that document is your claim.

No coverage, no problem

Logging, reading, importing, exporting and restoring all work with the phone in flight mode. Two things need a connection, and only when you ask for them: looking up the place name for a coordinate, and sending a backup somewhere.

The dive

Your dive profile, right there on the dive.

If your dive computer can export a file, Logbuoy reads the profile out of it and draws it. Anything your computer worked out is shown exactly as it recorded it, with the device's name against it.

  • Depth profiles come in with your UDDF and get drawn on the dive
  • Sites, regions and countries come from a built-in list, so one reef gets filed one way
  • Coordinates from your phone's GPS, typed in by hand, or left off
  • Search across sites, buddies and notes

The kit

What you own, what it cost, and when it was last serviced.

Every piece of gear carries its brand, model, serial number, photos, what you paid and in which currency, and the full history of what the shop has done to it. Retired kit stays on the list with a label on it, because a drysuit in the garage is still yours and still worth insuring.

  • Due in months, due in dives, or overdue, colour-coded and sorted
  • Prices in the currency of the country you bought it in
  • A printable gear list with thumbnails, ready for a claim
  • Brands and models are suggested as you type, and you can always type your own

Safety

Logbuoy remembers your dives. Your computer plans them.

Logbuoy will not work out a surface interval, a no-fly time, decompression or gas. That is what your dive computer, your tables and your training are for, and we are not putting a phone app in the middle of it.

What you import, you see. If your computer worked a number out, Logbuoy shows it exactly as your computer recorded it, with the device's name against it, and leaves it alone.

FAQ

Frequently asked questions.

Something we have missed? Write to support@woodfirelabs.com and we will answer.

Does it sync with my dive computer over Bluetooth?

No, because we deliberately want to stay vendor neutral. Every manufacturer's Bluetooth protocol is different, undocumented, and changes with firmware, so software that claims to support all of them is really supporting whichever models somebody happened to own.

Logbuoy reads the file your computer or its desktop software exports instead: UDDF or CSV, profiles included.

Where is my logbook actually stored?

In a database file on your phone, alongside the photos you attached. Logbuoy keeps dated copies of that file so you can roll back to an older one yourself, and you can send a copy to your own Drive, Dropbox or inbox through the share sheet whenever you like.

Can I get my dives back out?

Yes. Export the whole logbook as UDDF or CSV at any time. UDDF is the interchange format most serious dive software reads, so if you ever stop using Logbuoy your dives come with you.

Does it track me, or send anything anywhere?

No. Your secret dive locations are safe and not shared with anyone unless you choose to share them.

The company privacy policy is published in full.

Is there an iPhone version?

We decided to launch on Android first, but an iPhone version is under development. Stay tuned.

What does it cost?

Pricing is shown on the Google Play listing. We want to make this app ad-free, affordable, and supportable for the long term, but we are a small company. Your purchase means a great deal to us and allows us to keep developing the product.

What do I need to run it?

An Android phone or tablet on Android 8.0 or later. On a tablet the layout adapts: the navigation moves to a rail down the side and the logbook shows more dives at once.

Start a logbook you will still have in ten years.

Bring in the dives you already have, log the next one on the boat, and keep the whole thing on a device you own.
