One link. Your phone. Nothing to install.
When a host runs a stay in StayTurn, you get one link for that stay. It opens in your phone's browser. You confirm the window, take the photos, and send them. There is no app to download, no account to make, and nothing to pay.
How a turnover goes
The host sends you a link for this stay by text or email. It works for this stay only.
Open it, see the property and the dates, and confirm the window.
The same shots every time: wide, then close, before you start and when you're done.
The photos go to the host. They review each one before it joins the stay record. Nothing else is asked of you.

What the host sees
Your photos land in the host's stay as pending. The host looks at each one and accepts it into the record, next to the checklist, the costs and the notes for that stay. When a guest disputes something weeks later, the host has your photos with the date on them.
Your photos belong to the host's record for that stay. StayTurn sends you no messages of its own.

Straight answers

It opens in the phone's browser, iPhone or Android.
Each host sends their own links. Nothing to keep track of between them.
No. StayTurn doesn't dispatch, schedule or pay. Your arrangement with the host stays exactly as it is.
The host who sent it, or StayTurn support. The cleaner guide walks through each step.
