DoorMe

DoorMe turns the questions guests always ask — the wifi, the thermostat, the hot tub, check-out — into short video answers, all behind one QR code at the door.

Hosts film each answer once on their phone, in about twenty seconds. Guests scan the code and watch in their phone's browser: no app to download, no account. Every video is captioned automatically in ten languages, and guests can search for what they need.

DoorMe also shows hosts what guests searched for and couldn't find, so they know exactly what to film next.

Every feature is included on every plan, and every plan starts with 30 days free. On Google Play now; iPhone from November 1.
