Every dive, with its profile
Depth, temperature, tank pressure and gas switches come straight from your computer.
Your air consumption is worked out from real pressure data, dive after dive.
Log and import every dive, plan recreational and technical dives, and run your dive shop or club, on the web, iPhone, iPad and Android.

DiveHQ is a logbook, a dive planner and a back office. Divers keep every dive and plan the next one. Shops, clubs and instructors run their day here, and divers find them.
For divers. Log by hand or import from your dive computer, then keep your certifications, gear service dates and your own air consumption in one record that follows you from shop to shop.
For technical divers. Plan open-circuit trimix and rebreather dives with ZHL-16C gradient factors or VPM-B, with bailout, gas volumes, CNS and OTU, END and density warnings, and wetnotes you can print.
For shops and clubs. Boat trips, bookings, waivers, medical forms, cert checks, courses, rentals, fill logs, retail and memberships across every location, with a booking page under your own name.
On the boat. The phone and tablet apps work offline. Log dives, plan, check divers in and sign waivers with no signal, and it all syncs when you are back at the dock.


A sample day at a Key Largo shop. Select a trip to see its check-in, waivers, cert checks and fills as the dock crew sees them.
Depth, temperature, tank pressure and gas switches come straight from your computer.
Your air consumption is worked out from real pressure data, dive after dive.
Old logs from Subsurface, MacDive or Diving Log come in with their profiles.
Duplicates are caught before anything is saved, and you choose what to keep.
Dive tables, no-deco limits, nitrox MOD and best mix, turn pressures and rock bottom.
Every figure is worked from your own consumption, not a generic number.
Open circuit or rebreather, ZHL-16C with gradient factors or VPM-B, with bailout.
Every plan checks ppO₂, END, gas density and gas switches, and prints as wetnotes.
Signed dives count as proof of experience when you sign up for your next course.
Shops can verify your cards, so you show them once, not at every counter.

Sample listings. The directory opens with shop accounts.

Dues, events, buddy pairing, carpools, minutes and a shared club log.

No. Your computer tracks the dive you are actually doing. DiveHQ keeps the record afterwards and helps you plan before you get wet. The planners show their working so you can check them against your computer and your training.
Anything that exports UDDF or Subsurface XML, plus Shearwater Cloud, Garmin FIT, Suunto, MacDive, Diving Log and DAN DL7 files. The phone app downloads over Bluetooth from Shearwater, Suunto, Garmin, Mares and other common models.
Every release runs a reference suite of published Bühlmann ZHL-16C and VPM-B profiles, plus checks that more conservative settings never shorten decompression. Each saved plan records the engine version and inputs so it can be reproduced exactly.
Yes. The iPhone, iPad and Android apps keep your logbook, planners and tables on the device. Shop tablets keep the day’s manifests, waivers and rentals. Everything syncs when you are back in range.
Yes. Connect your own Stripe account and divers pay you directly for trips, courses and rentals. If you would rather take payment at the counter, mark bookings as paid instead. Each shop chooses.
Export your whole logbook as UDDF or JSON at any time, including profiles, gas and signatures. Deleting your account removes your data after 30 days.
Certifications from PADI, SSI, NAUI, SDI/TDI, GUE, IANTD, RAID, BSAC, CMAS, UTD and others. Shops and instructors can mark a card as verified, which other shops can see when you book.
Only staff at a shop you book with, and only the roles that need it. The form is encrypted, every view is recorded, and you can withdraw a shop’s access at any time.
Your logbook is ready as soon as you sign up. Shops and clubs can add a location and invite their staff before choosing a plan.
