Whichever runs out first
Service intervals can be set in months, in dives, or both. A regulator that has done 150 dives in eight months comes up on the dive count, even though the year is not up.

DiveKit
Scuba Gear & Service
Find out at home, not at the fill station.
DiveKit keeps the service and inspection dates for every piece of your kit — and for cylinders it answers the only question that matters at the counter: can this be filled, with air, with nitrox, or neither.
14-day trial, then $24.99 once,
$9.99/yr or $1.99/mo. Android.
THE QUESTION A STICKER CANNOT ANSWER
One tank. Two different answers.
A cylinder does not have one expiry date, it has three, running independently. An air fill needs a current visual inspection and a current hydro. A nitrox fill needs both of those and a current O2 clean. So a tank can be perfectly fine for air and turned away for nitrox on the same morning — which is why DiveKit answers the two separately instead of showing one status light.
ONE CYLINDER, FROM THE APP'S SAMPLE KIT
- Visual inspection (VIP) Current
- Hydrostatic test Current
- O2 clean Expired
Air fill
Ready
Visual and hydro both current.
Nitrox fill
Blocked
O2 clean expired.
Same tank, same day. DiveKit names the blocker rather than just refusing, so you know what to book. A cylinder you have not flagged for nitrox is never shown a nitrox verdict at all — no irrelevant red on an air-only tank.
02
Your intervals, not ours
DiveKit starts at 12 months for a visual and 5 years for a hydro, then lets you change every one. Inspection rules genuinely differ between countries and the app does not pretend otherwise.
03
Warned a month out
Anything within 30 days of its date turns amber, and an optional notification tells you 30 days before — enough time to book a shop rather than find out on the boat.
What it does
Six things, recorded properly. No account to make, nothing uploads.
-
01
Two service clocks per item
Set an interval in months, in dives, or both. Whichever runs out first is the one DiveKit counts.
-
02
Cylinder inspections
Visual inspection and hydrostatic test on their own clocks, with editable intervals — the rules differ by country.
-
03
O2 clean for nitrox
Tanks you flag for nitrox carry a third clock. Tanks you do not are never shown a nitrox verdict at all.
-
04
Dives as a usage count
Log a dive as a simple tally. It feeds every usage clock you set, so a heavy season moves your service dates.
-
05
Service history with photos
Date, what was done, who did it, cost and receipt photos — kept against the piece of kit it belongs to.
-
06
Reports you can hand over
A full service report PDF, a single-item Gear Passport for a resale or a claim, and CSV of your inventory and history.
The app itself
Three screens from the shipped build. The kit, the dates and the shop names in them are sample data.

Built for kit you own and trust
- Works fully offline. No account, no cloud sync. Your records stay on the phone, which is the right answer on a liveaboard with no signal.
- Nothing you recorded is ever hidden. When the trial ends, the free tier caps new gear at three items. Everything already logged stays readable and exportable.
- A record you can hand over. A Gear Passport PDF covers one item with its full history — the document to send with a regulator you are selling, or with an insurance claim.
- It logs, it does not certify. DiveKit reduces the risk of a missed inspection. It does not certify that equipment is safe, and it does not replace a qualified technician.

Questions
Is DiveKit a dive log?
No. It does not record depth, bottom time, gas mixes or buddies. It tracks service and inspection dates for your equipment, and counts dives only as a number that moves your service clocks.
How does the air and nitrox check differ?
An air fill needs a current visual inspection and hydrostatic test. A nitrox fill needs both of those plus a current O2 clean, so one tank can be ready for air and blocked for nitrox.
Where do the inspection intervals come from?
From you. DiveKit starts with 12 months for a visual, 5 years for a hydro and 12 months for an O2 clean, and every one of them is editable, because the rules genuinely differ by country.
Does it work offline?
Completely. There is no account and no cloud sync — your records stay on your phone, and exports are files you keep.
What happens when the trial ends?
Everything you already recorded stays readable, forever. The $0 tier keeps three items of kit; unlocking removes the cap and the ads.
Is there an iPhone version?
Android only for now.
