The steps

1. Walk up, and Dromo names the door you are standing at, with how far it thinks you are from it.
2. It also tells you this door has been tried before: third time here, the last one earlier today.
3. Tap More for the whole opener.
4. It comes filled in for this house: their name, their street, their date of birth, and your own name in it. The grey lines are the coaching, not the words to say.
5. Knocked here before? Knocked again logs the same outcome in one tap, and writes the note for you.
6. Logged. And Dromo moves straight on to the next door, twenty six yards up the street.
7. Every other outcome is one tap too.
8. With no signal it is kept on the phone and sent the moment you have a bar, so keep knocking.
9. And if you are between two houses, this shows the other doors within reach.
10. Pick the one you are actually standing at.
