Include your iOS version, the challenge type, and roughly what time it happened. If it was a scoring question, the result link helps most — the address of the card, which pins the exact challenge.
If a result is wrong, say so and say why you think so. Every challenge is adjudicated on the server from timestamps it holds, so a disagreement is something we can actually go and look at.
Tapping an invite is supposed to open Upend. When it opens the website instead, the app is installed but iOS has not yet associated the domain with it. This is normal on a fresh install and usually resolves itself.
Upend schedules a real system alarm, and iOS asks permission for it the first time. If the alarm is not firing, check that Upend is allowed to schedule alarms in Settings, and that Focus or Do Not Disturb is not silencing it.
Two behaviours are deliberate and worth knowing:
That is on purpose, and it means the camera is unavailable — usually because camera access is off for Upend in Settings, occasionally because another app has the camera.
A shutter that appeared to work without a camera would credit you for evidence that does not exist, so it is dead rather than optimistic. Turn camera access on, or leave the screen and self-report — the challenge still resolves either way, one level down the verification ladder.
Rep counting reads your body pose from the camera, and it is honest about when it cannot see you. Two things help most: stand facing the phone, and give it a moment of stillness before you start and after you finish.
If the count is not confirmed, the app asks you how many you actually did rather than guessing. That is the design — under-counting costs you a win you earned and you can see it happen; over-counting is silent and unearned, so we prefer the first.
If the challenge button is missing from a rival, their series with you is paused. That happens after three no-shows in a row, and it is a circuit breaker rather than a punishment: someone who has stopped showing up should not keep receiving alarms from you.
Only they can restart it, with one tap, whenever they like. There is nothing you need to do and nothing to apologise for.
An invite nobody accepts is cancelled — at your own wake alarm, or 48 hours after it was created, whichever comes first. Nobody loses; there was no race. Send a new one.
In the app: your name under You, then Delete account. Apple confirms it, and the account and everything attached to it is gone. If you cannot get into the app, email support@getupend.com from the device you signed in on. What is removed, and what happens to a race in progress, is spelled out on the privacy page.
