Never run out of cooking gas by surprise.
GasOK sits under your cylinder and shows how much gas is left, and how many days until you need a refill, right on your phone.
Ready in three steps
No plumber, no gas work. Set it up in a few minutes.
Place it under the cylinder
Put the GasOK sensor under the bottom of your gas cylinder. That's the whole installation.
Scan your GasOK code
Open the GasOK app and scan the code that came with your sensor. It's now linked to your account.
See gas left, every day
Check the level and the days left any time. GasOK warns you before you run out.
Everything about your gas, in one app
Gas left, in % and kg
A clear reading of what's in the cylinder, not a guess from shaking it.
Days left
GasOK learns how much you cook and tells you how many days the gas will last.
Low-gas alerts
A reminder in good time, so the gas never finishes in the middle of cooking.
Usage history
See how much gas you use each week and how long each refill lasted.
Bluetooth, Wi-Fi or 4G

More than one cylinder
Home, shop or kitchen: add every GasOK sensor to the same account.
Your sensor is matched to you
Every GasOK sensor is checked and matched to its own GasOK code before it leaves our office. When you activate it, it's locked to your account, so nobody else can use it.

How does GasOK measure the gas?
The GasOK sensor sits under your cylinder and measures the liquid gas level through the steel bottom. Nothing is opened or connected to the gas, and there is no hose or valve change.
Do I need internet or data?
It depends on the model. GasOK Bluetooth talks to your phone, so readings work without data. GasOK Wi-Fi uses your home Wi-Fi, and GasOK 4G has its own mobile connection, so you can check your gas from anywhere.
Which cylinders does it work with?
Standard steel home LPG cylinders. You choose your cylinder size in the app so GasOK can show kilograms and days left. Sizes list to confirm
What if I bought a sensor from another seller?
Only genuine GasOK sensors can be activated. Each sensor is matched to a GasOK code before sale, so a sensor bought elsewhere won't work with the GasOK app.
