Gasos runs in the browser, and you can install it like an app. It gets its own icon, opens full screen without the browser bar, and starts faster on a weak connection. There’s nothing to download from a store, and it updates itself.

​
On an Android phone

  1. Open gasos.ng/app in Chrome and sign in.
  2. Tap the ? at the top right of any page, then Install Gasos.
  3. Tap Install.
You can also use Chrome’s menu (⋮) and tap Install app or Add to Home screen.

​
On an iPhone or iPad

  1. Open gasos.ng/app in Safari and sign in.
  2. Tap Share (the square with an arrow) in the browser bar.
  3. Tap Add to Home Screen. You may need to scroll down.
  4. Tap Add.
The ? menu’s Install Gasos shows these steps too.

​
On a computer

In Chrome or Edge, open Gasos and click ? at the top right, then Install Gasos. Or click the install icon at the right of the address bar. Gasos then opens in its own window and can be pinned to the taskbar or dock. On a Mac with Safari, choose File → Add to Dock.

​
What works without a connection

Once you’ve used Gasos online on a device, it opens without a connection, straight into your workspace. Readings, photos and till sales wait on the device and send when you’re back online. There are a few things to do first and some rules that keep unsent work safe. Read Working offline before relying on it at a station.

​
Updates

When there’s a new version, Gasos shows A new version of Gasos is ready. Tap Reload when you’re at a good point. It never reloads by itself, so nothing you’re typing is lost.

​
Removing it

Remove it like any app: press and hold the icon and choose Remove or Uninstall. On a computer, open the app’s menu and choose Uninstall.
