WebAppsToolBox
Small, sharp tools
for divers and their kit.
Six applications, each doing one job properly: keeping the records that breathing-air compressors, rebreathers, dive kit, dive sites and dive planning actually depend on — and keeping them somewhere you can reach from anywhere.
The six applications
Built in this order, because the first one shapes everything after it.
Air Compressor Logger
Run hours, filter and cartridge changes, service intervals and air quality test results for a breathing-air compressor — so the next service is a date, not a guess.
Read more → PlannedRebreather Scrubber Logger
Sorb life tracked across dives and across units, with the elapsed time and conditions that actually consume it — so a scrubber is never run on memory.
Read more → PlannedScuba Diving Formulas
The gas, pressure and depth calculations divers reach for repeatedly, in one place, with the working shown rather than hidden behind a single number.
Read more → PlannedPoseidon Se7en Error Checker
Turn a Se7en error or warning code into plain language: what it means, what usually causes it, and what to check before the next dive.
Read more → PlannedScuba Equipment Service Calendar
Every service and expiry date across every piece of kit — regulators, cylinders, computers, cells, drysuits — on one calendar that warns you in time to book.
Read more → PlannedDive Site Location Logger
Where the site actually is, where to park, where to get in, what the bottom does — and which conditions make it worth the drive. Works with no signal.
Read more →One account. Your data, wherever you are.
These are logbooks. A logbook that only exists on one device is a logbook you will eventually lose — so the design starts from the opposite end.
Sign in with an account you already have
Apple, Google or Microsoft. We never ask you to invent another password, and we never store one — there is nothing there to leak.
The same records on every device
Your entries live on the server, not in one browser. Open a different machine, or the phone in your pocket, and the log is the log.
Native apps are the plan, not an afterthought
Each application is being built API-first, so the iOS, iPadOS and Android versions are genuine native apps over the same data — not a website in a wrapper.
Built for one diver first
Every one of these started as something we needed ourselves. They get used in anger long before anyone is asked to pay for them.
