Feature

A barcode alarm clock built on iOS 26 system alarms

BarLock is built around iPhone alarm behavior and a real-world scan mission, so dismissal requires more than tapping a button.

For iPhone users who want a stricter alarm without turning the morning into a complicated setup.

Why it fits

Make dismissal prove movement.

The app keeps the loop narrow: set the alarm, choose the scan target, let iOS ring, scan the item, and confirm you stayed awake if needed.

The problem

System alarms, not background workarounds

The barcode alarm clock idea is not new. What is new is iOS finally providing a real foundation for it. Older camera-alarm apps predate AlarmKit, so they lean on background audio sessions and notification tricks to keep ringing, and the whole mechanic can collapse if the app is force-quit or the phone decides to reclaim memory overnight.

BarLock is built on AlarmKit, the system alarm framework Apple introduced in iOS 26. Protected alarms ring through the system with system reliability, and the app's job starts where the system's ends: opening the scanner and holding the line until the saved barcode or QR code is verified.

Around that core sit the controls that make a barcode alarm clock practical instead of gimmicky: a Lock Window so the mission cannot be quietly edited before it fires, Backup Alerts for early stops, a Wake-Up Check for the minutes after, Tiptoe Mode so the alarm goes quiet after Stop while you reach the code, and repeat schedules so one setup covers the week. No account, no feed, no sleep-content upsell. It is an alarm clock.
