Something not badgering right?

Breakthrough alerts need alarm permission. Open Settings › BadgerMe and confirm alarms are allowed, then check two things inside the app: that the Badger is still active (not already marked Done), and that a Focus filter isn't capping its prominence for the Focus you're currently in. If alarms were denied, the Badger falls back to notifications only.

No, and this is deliberate. Stop silences the one alert that's sounding; it does not resolve the Badger, so the ladder keeps climbing. To actually end it, mark it Done. (If you want it gone without resolving, use Stop-the-Badger or Delete — see below.)

Also by design. Snoozing the same Badger repeatedly makes it climb a rung on its own after a few tries, so it comes back louder. If you're genuinely done, mark it Done; if you want to call the whole thing off, Stop the Badger. You can raise its snooze tolerance when you build the ladder.

Custom sounds have to be 30 seconds or shorter and in a supported encoding — Linear PCM, IMA4, µ-law, or A-law, packaged as a .caf file. AAC and MP3 aren't accepted. Convert the file and re-import it. A sound that's since been deleted falls back to the default.

Everything — your Badgers, their history, and any sounds you import — lives only in BadgerMe's private storage on your device. There's no cloud in this version, so there's nothing to sign into and nothing to sync. Deleting the app removes all of it, and a reinstall starts fresh.

Marking a Badger Done clears its pending alerts. A banner that already arrived before you resolved it can simply be swiped away.

Yes. You can create a Badger, mark one done, and snooze through Siri, the Shortcuts app, the Home- and Lock-Screen widgets, and a Control Center control — the app is built to be driven without opening it.

Three options, depending on what you want: Done resolves it (kept in your history as completed), Stop ends it without marking it complete (also kept in history), and Delete removes it and its history entirely.
