Example apps

Three real examples. Open one on your phone and add it to your home screen — then turn off your data and open it again.

What it does

• Works with no signal. Once a guest has opened it, the whole thing stays on their phone — prices, hours, your number.
• Installs like an app. Your name and icon sit on their home screen for the rest of the trip. No App Store, nothing to download.
• One tap to message you. The button at the bottom opens WhatsApp with the first line already written.
• You change the prices. Edit one cell in a spreadsheet; the app updates itself.
