Something not behaving? Start here.
Crosses is a small app with a small number of things that can go sideways. Below are the questions that come up most. If yours is not here, the email address at the bottom reaches a person, not a queue.

Accounts, rooms, and what you need.
How do I sign in?
Two ways, both passwordless. Enter your email and Crosses sends you a magic link — tap it on the same phone and you are in. Or use Sign in with Apple, which skips the email round trip entirely.
Magic links expire fairly quickly. If you get an error about an expired or invalid link, request a new one rather than reusing the old email.
How do I join a room?
A room is a team, shop, or club that shares machines. Someone already in the room invites you, or shares it with you — you do not create your own room to join an existing one. If you are setting up a room for the first time, do it from Manage Rooms in the app.
Stuck without an invite? Email support and say which room you are trying to reach.
What iPhone do I need?
Crosses currently requires iOS 26. That is a deliberate choice for the beta rather than a permanent floor, but if your phone is on an older version the app will not install. Check Settings → General → Software Update.
Tags, status, and notifications.
What do the machine tags do?
Each machine gets one NFC tag. Holding your phone near it opens Crosses straight onto that machine, so starting a session is a tap rather than a hunt through a list.
Tags are set up once, from the app, by whoever manages the room. You do not need to configure anything to use one.
I tapped a tag and got a web page instead of the app.
That is the fallback for phones without Crosses installed — it means iOS did not hand the link to the app. Usually it is one of three things: the app is not installed, you opened the link from a context iOS treats as a plain web link, or the phone has not yet picked up the app's link registration.
Try opening Crosses once directly, then tap the tag again. If it keeps happening, email support with the machine name and what the page showed.
The room shows a machine as busy, but it is standing free.
Status comes from sessions people actually start and finish in the app. If someone walked away without ending theirs, it stays busy until the session's estimate runs out. Anyone in the room can end a stale session from the machine's screen.
If a machine is stuck busy with no session behind it at all, that is a bug worth reporting — include the machine name and roughly when it happened.
I never got the “machine is free” notification.
Those alerts are scheduled locally on your phone, so they need notification permission. Check Settings → Notifications → Crosses, and that notifications are on in the app's own Profile settings.
Because they are local rather than pushed from a server, they fire based on the current session's estimate. A session that runs long past its estimate will have already notified you.
Can I change my display name or photo?
Yes — in the app, under Profile. Your display name and photo are what other members of your room see.
Testing, reporting, and leaving.
I am a beta tester. How do I report a bug?
From TestFlight itself: take a screenshot in Crosses and TestFlight will offer to send feedback, or open TestFlight → Crosses → Send Feedback. That route attaches your device and build details automatically, which makes a report far easier to act on.
Email works too if you would rather write it out. Either way, what helps most is what you expected, what happened, and roughly when.
How do I get into the beta?
Beta access goes out by invitation to the email address on your Apple ID. If you joined the early-access list on the home page, that is the list invitations come from. If you are expecting an invite that has not arrived, check the address you signed up with, then email support.
How do I delete my account and my data?
Email support@crossesapp.com from the address on your account and ask for deletion. Your profile, photo, and session records are removed, typically well inside 30 days. The privacy page spells out exactly what goes and the one thing that does not.
Write, and you get a reply.
Crosses is early and small, so replies come from a person rather than a support desk. Expect an answer within a couple of days.
Things that make a bug report easy to fix: what you were trying to do, what happened instead, the machine or room it involved, and roughly when. A screenshot beats a paragraph every time.
For anything about your data — what is stored, or getting it deleted — the privacy page answers most of it, and the same address handles the rest.
