HotlineHotline or a timer in Shortcuts
You don't need Hotline to ring an alarm from a notification. A Shortcuts automation can start a timer or create an alarm in the Clock app, and for one simple trigger that works well. Both ring through Silent and Focus, as loud as any alarm.
This page is what each one does once it rings, so you can decide whether you need Hotline. We tried the timer, the alarm and the Shortcuts actions around them on an iPhone and wrote down what we saw.
| Start Timer | Create Alarm | Hotline | |
|---|---|---|---|
| Rings | About 2 seconds after the notification (a 1-second timer) | Up to a minute later, or tomorrow if set for the current minute | 3 to 5 seconds after the notification: the same automation hands it over, then a 1-second alarm |
| How long it sounds | 15 minutes, then silent on screen until stopped | 15 minutes, then silent on screen until stopped | 15 minutes to 2½ hours, per channel: a fresh alarm every 15 minutes |
| What the alarm says | "Timer" | Its label, cut to about 41 characters | The sender and message, cut to 40 characters |
| Snooze | No | Yes | Yes, per channel |
| Sound | The one set in Clock | The one set in Clock | One per channel, or your own |
| Several notifications | A timer each | An alarm each | One alarm |
| Add a new source | Edit the shortcut | Edit the shortcut | Add a channel |
| Check a rule before it matters | No | No | Preview against recent notifications |
| When a step fails | A Shortcuts notification | A Shortcuts notification | A Hotline notice, and History |
| Turn it all off for a while | Switch the automation off in Shortcuts | Switch the automation off in Shortcuts | From Control Center or the Lock Screen |
| Left behind | Nothing | An alarm in Clock | Nothing |
Start Timer
Set to 1 second, a timer rang 1.5 to 2.1 seconds after each notification that ran the automation.
- It says "Timer". On the Lock Screen it rings full screen with the time, Repeat and slide to stop; unlocked, it's a banner that says "Timer". Nothing on it tells you what arrived. Start Timer has no label, so a Show Notification beside it is the only way to see the message.
- No snooze. You stop it or start it again from the full time.
- One sound. Start Timer has no sound option, so every timer uses the sound set in the Clock app.
- Every notification adds a timer. Five notifications 2 seconds apart started five timers, stacked in Notification Center, each stopped on its own.
- 15 minutes of sound. iOS stops a timer's sound after 15 minutes. The timer stays on screen, silent, until you stop it.
- A shortcut can't tell that a timer is ringing. Get Current Timer returns 0 seconds while a timer rings, the same as when there's none, so a shortcut that wants to avoid stacking has to keep its own record of when it last rang.
- Shortcuts can't stop a ringing timer. Cancel Timer cancels one that's still counting down; a ringing one keeps ringing.
Create Alarm
Create Alarm (shown as Add Alarm in the action list) makes a real alarm in the Clock app, with a label that can carry the message.
- It rings late. The time is a time of day, to the minute. "In 1 minute" isn't accepted, so the shortcut has to work out the time itself, and both choices cost something: the current minute rings tomorrow, 24 hours late, and the next minute rings up to a minute after the notification.
- The label carries the message. On the Lock Screen it gets two lines, about 41 characters on an iPhone SE. When your iPhone is unlocked, the ringing alarm is a row on the Lock Screen and in Notification Center with about 20 characters. (Hotline's alarm shows the same way there: that's how iOS shows alarms.)
- Snooze is on by default. There's no sound option.
- 15 minutes of sound, like a timer. Then it stays on screen, silent, until you stop or snooze it.
- Each alarm stays in Clock until you or the shortcut delete it.
- Turning it off doesn't stop it. Toggle Alarm said "Your 3:08 PM alarm is now Off." while the alarm kept ringing. Delete Alarms does stop it, but asks "Allow … to delete 1 alarm?" every time. With Allow Deleting Without Confirmation on (Settings › Apps › Shortcuts › Advanced), that prompt gets a Delete Always button, and once you tap it the shortcut deletes without asking.
Urgent reminders
The Reminders app can mark a reminder Urgent, which rings an alarm with the reminder's title through Silent and Focus. A shortcut can't set it: neither New Reminder nor Edit Reminder has an Urgent option, so you mark each one by hand. Reminders also says urgent alarms ring only on the device Find My uses as your location, which may not be the iPhone the notification arrived on. Once we made our test iPhone that device, an urgent reminder rang about 5 seconds after its time: unlocked, a banner with the reminder's title, snooze and stop. The phone's log gives it the same 15-minute limit as a timer.
When a step fails
We expected a failed DIY automation to fail silently. It doesn't: when a step failed with the iPhone locked, Shortcuts posted a notification with the automation's name and the error ("The file doesn't exist."), and nothing rang. Like Hotline's own notices, it's an ordinary notification, so Do Not Disturb and Focus silence it.
What Hotline adds
- The message on the alarm, within seconds. An immediate channel rings a 1-second alarm as soon as the automation hands it the notification, with the sender and message as the alarm's title. On our iPhone it rang 3 to 4 seconds after the notification, or up to 5 when Hotline wasn't already running: a second or two slower than a timer, because the alarm's 1-second countdown took 2.
- One alarm, not a pile. While a channel's alarm rings, more matching notifications don't start another; History lists them as "Alarm already active".
- Sound, snooze and how long it rings (up to 2½ hours, past iOS's 15-minute limit), set per channel, including your own sounds with Hotline Pro.
- Off from Control Center. Turn all of Hotline off and on from Control Center or the Lock Screen, with every channel kept as it was; History still shows what would have rung.
- A countdown you can cancel. A channel can wait before ringing, with a Live Activity on the Lock Screen to pause or cancel it.
- Rules with a memory. Cooldowns and "3 times in 10 minutes" need a record of what arrived. A shortcut can keep one, in its own storage (Store Content, new in iOS 27), a file or an app such as Data Jar, if you build the reading, counting and clearing around it; Hotline keeps it for you.
- Channels, not a growing shortcut. One automation sends everything in; each source is a channel with its own apps, people, words, hours, sound and snooze, that you add, change or pause in the app.
- Check a rule before it matters. A channel shows which of your recent notifications it would have rung for while you edit it, and History shows every notification and why it did or didn't ring. In Shortcuts, that log is another file your shortcut has to write.
Keep your shortcut, use Hotline's alarm
If you already have a shortcut that decides what matters, keep it. Replace Start Timer or Create Alarm at the end with Ring Hotline Channel: your shortcut decides, and Hotline rings the alarm with the message on it. If your shortcut already does everything you need, you're not missing much.
Setup and the two Shortcuts actions are on the Support page.
