Install on phone, tablet, or computer

InvUltra is a website that installs like an app. The counter then opens full screen, without the browser bar.

Steps

1. On a computer, open web.invultra.com and sign in.
2. When the header shows Install App, click it.
3. On Android, open Chrome, then use Install app or Add to Home screen.
4. On iPhone, open Safari, tap Share, then Add to Home Screen.
5. Open the new icon. The app fills the screen.

Do not make a sale in this step. Products and the register come next. The same installed app is what keeps selling when Wi-Fi drops. See Sell without internet.

Next: Find your way around.
