Some notifications matter more than others. Bell Alerts lets you give each one its own sound — so you know what just happened without even looking at your phone. Create a bell, share its code, and ring it. Everyone you've shared it with gets the alert instantly — each on their own phone, with the sound they picked. Dinner's ready, the dog's at the door, the meeting's starting: make it a bell. MAKE IT YOURS • A different sound for every bell — a dozen original tones to choose from • Per phone: you pick your sound, your family picks theirs • Vibrate-only or mute any bell, anytime • 11 app icons to match your style SEND A BELL IN A TAP • Create a bell — it gets its own private, unguessable code • Share the code; anyone who adds it is subscribed • Ring it from the app — or straight from a Home Screen widget, without opening anything • Changed your mind? "Oops" un-rings it — the alert crosses itself out everywhere STAY ON TOP OF IT • Recent rings at a glance, with timestamps — canceled ones clearly marked • A Home Screen widget shows the latest bells the moment they ring • Disappearing alerts tidy themselves up after a time you set PRIVATE BY DESIGN • No account, no sign-up, no tracking • Bells are private codes — only the people you share them with get the rings • Verified on device with App Check; standard encryption only FOR POWER USERS Bell Alerts can also receive alerts from your own internet server — the same bring-your-own-server idea as the open-source app ntfy. Send a notification from any script or service you run and it arrives as a custom bell on every subscribed phone. It's a software integration over the internet; no extra hardware or accessory is involved. Setup guide included. Make every alert sound like what it is.
