Nobody appears in the list

Both phones need HawaDrop open and on screen. You are only visible while the app is in front of you.
Bluetooth and Wi-Fi both need to be on. You do not need to be joined to a network, but the Wi-Fi switch must be on, exactly as AirDrop requires.
HawaDrop needs permission to use the local network. If you said No when asked, open Settings, find HawaDrop and switch Local Network on. iOS only asks once.
Move closer. Range is similar to AirDrop, and walls, cars and crowds all shorten it.

A transfer failed partway

Move the phones closer together and try again. Nothing partial is kept: a file that does not arrive completely is discarded rather than saved half-finished.

Where received files go

The Files app, in a folder called HawaDrop. Tap a file in the app when it arrives to open it straight away.

Does this work without internet?

Yes. HawaDrop never uses the internet. The phones talk to each other directly, so it works with no signal, no data and no Wi-Fi network.
