Cylinder stickers for analyzed gas

Make every cylinder label unmistakable.

Turn checked gas values into labels divers can read at the fill bench, on the boat, and during team handoffs.

Analyze and verify the gas first. The app helps make the label clear.

Why labels matter

The label is read when people are moving fast.

Fill rooms are noisy. Boat decks are crowded. Tech teams move cylinders between benches, cars, boats, and water. A label has to make the important fields easy to find before anyone breathes from that cylinder.

01

Gas identity

Put the gas name and mix where a diver looks first.

02

Depth and use limit

Keep MOD and ppO2 beside the mix, not buried in a note.

03

Cylinder role

Make stage, deco, bailout, diluent, oxygen, rental, and team cylinders obvious.

04

Handoff clarity

Show owner, team, pressure, date, and role before the cylinder changes hands.

How it works

Analyze first. Check the plan. Print the label.

The app is for the label step after the real checks. Calibrate the analyzer, analyze the cylinder, confirm MOD and ppO2, then print the fields in a layout other divers can read quickly.

01

Analyze with your own equipment

Use a calibrated analyzer and the procedure you were trained to use.

02

Enter the fields divers actually check

Gas, O2, He, MOD, ppO2, pressure, owner, role, and analysis date.

03

Print the sticker

Send the label to a configured local Zebra printer over Wi-Fi or Bluetooth.

04

Save repeat work locally

Duplicate and reprint common fills without typing the same fields again.

From analyzer to label

Enter the gas. Check the values. Print the label.

Scan the analyzer display or enter O2 and He manually. Review every field, then print directly to your configured Zebra printer.

What changes at the bench

Less decoding. More checking.

The mix is not a scribble

O2, He, gas name, and MOD are placed where eyes expect them.

Repeat fills take less typing

Saved local history helps with course sets, team cylinders, and regular customers.

The shop looks organized

Customers see one clear label standard instead of different handwriting every time.

Fewer handoff questions

Owner, role, pressure, and date travel with the cylinder.

Label system

One clear layout language for critical cylinder information.

Critical fields stay in predictable positions, so divers and staff do not have to decode handwriting during a fill-room rush or team check.

Built for repeat label work

Made for people who label more than one cylinder at a time.

Individual divers can use it, but the workflow is shaped by fill stations, dive centres, instructors, liveaboards, and tech/CCR teams who keep seeing the same label problems.

See dive-centre workflow

Dive centres

Customer pickups, rental cylinders, course cylinders, and repeat fills need one readable label standard.

Fill stations

Staff can move from analyzed gas to label handoff without rewriting the same fields on tape.

Tech and CCR teams

Stage, deco, bailout, diluent, oxygen, and team cylinders need clear roles and limits.

Launch feedback

Preparing the App Store launch around real label work.

The first useful release needs field feedback from people who print or check cylinder labels when the bench is busy. We are looking for practical workflows, printer details, and photos of real labels in use.

Best first testers

Dive centres, fill stations, instructors, and tech/CCR teams with repeat label work.

Details that matter

Printer model, label stock, device model, gas mixes, cylinder roles, and where labels are read.

Proof we need

Real labels on cylinders, Zebra output, analyzer bench photos, and readable MOD/gas examples.

iOS/iPadOS app support

Local sticker creation, printing, and OCR without accounts or cloud sync.

Scuba Tank Stickers is a paid, local-first iOS/iPadOS utility. It keeps sticker history, defaults, and printer settings on the device. It sends print jobs only to configured local Zebra Wi-Fi or Bluetooth printers, and gas analyzer OCR stays on device.

Use-case guides

Guides for real label jobs.

Use these when you need a specific cylinder, gas, role, or printer workflow. Each guide keeps the label honest: analyzed gas first, readable fields second.
