Bellringer
Real alarms for every meeting.
Calendar notifications are easy to miss. Bellringer turns the meetings in every calendar on your iPhone and iPad into real alarms, the kind the Clock app uses, so they ring through Silent mode and Focus. You set rules once for which meetings ring and how early, and the ones you've declined or are optional for can stay quiet.
Coming soon to the App Store, for iOS 26.1 and later

A meeting didn't ring. What should I check?
Open the meeting in Bellringer first. It says whether it will ring and why. If there's no alarm, a rule or a choice you made for that meeting is keeping it quiet, and you can change that on the same screen.
If the meeting isn't in Bellringer at all, check that its calendar is on in Bellringer's Settings › Calendars, and that iOS has fetched it from your account (see the next question). If it says alarms are off, allow alarms for Bellringer in the Settings app.
A meeting was added on another device. When will Bellringer see it?
Once iOS has fetched it from your account, and that's the part people trip over. With Fetch New Data set to Automatically, iOS may only fetch while your iPhone is charging on Wi‑Fi. Choose Push, or Every 15 Minutes, in Settings › Apps › Mail › Mail Accounts › Fetch New Data.
Bellringer then checks in the background as often as iOS allows. For checks at times you pick, like when your morning alarm is stopped, add Bellringer's Update Alarms action to a Shortcuts automation. A meeting it finds after its alarm time rings straight away.
Which calendars does it work with?
All of them, as long as iOS knows about them: iCloud, Google, Outlook and Exchange, any CalDAV account, subscribed calendars, and calendars kept only on your device. Accounts are added in the Settings app, so Bellringer never asks for a password.
If the same meeting is in two accounts, does it ring twice?
No, it rings once.
Can I keep meeting names off the Lock Screen?
Yes. In Bellringer's Settings, under Privacy, hide titles for every calendar or only some. The alarm then shows the time instead, like "10:30 AM meeting".
Does Bellringer send my calendar anywhere?
No. There's no account and no server, and no analytics either. The privacy policy spells out what it reads and what it keeps.
