Comparison
BarLock vs Barcode Alarm Clock
Barcode Alarm Clock proved the mechanic more than a decade ago: if the alarm ends at a barcode, you have to get up. BarLock is the same idea rebuilt on Apple's modern alarm foundation.
The short version
Both apps end the alarm at a barcode. The difference is the decade between them: BarLock rings through AlarmKit system alarms and wraps the scan in lock windows, re-ring, and a wake check after dismissal.
Side by side
BarLock and Barcode Alarm Clock, compared.
| Dimension | BarLock | Barcode Alarm Clock |
|---|---|---|
| Core mechanic | Scan a saved barcode or QR code to stop the alarm | Scan a barcode to stop the alarm |
| Alarm foundation | AlarmKit system alarms, introduced in iOS 26 | Built long before AlarmKit existed, as of this writing |
| Before the alarm | Lock window prevents sleepy edits to the mission | Standard alarm editing |
| After dismissal | Re-ring after early stops and an optional wake check | The routine ends at the scan |
| Pricing model | Free core routine, one-time Lifetime Pro upgrade | Free version plus a separate paid Pro app, as of this writing |
Choose BarLock if
- You want the alarm to ring through iOS system alarms rather than app-level workarounds.
- You want protection around the scan: lock windows before, re-ring and wake checks after.
- You want an interface designed for modern iPhones.
Choose Barcode Alarm Clock if
- You already own it and the routine still works for you.
- You want the longest-standing app in the category.
To be fair
Credit where it is due: Barcode Alarm Clock invented this category on the iPhone and kept it alive for years. BarLock starts from the same insight and rebuilds it on the alarm infrastructure Apple now provides, with the routine controls a decade of mornings taught the category to need.
FAQ
Common questions.
What is a barcode alarm clock?
An alarm that can only be dismissed by scanning a specific barcode or QR code with your phone's camera. Because the code lives on a real object away from your bed, stopping the alarm requires getting up.
How is BarLock different from older barcode alarm apps?
BarLock uses AlarmKit, the iOS system alarm framework, so protected alarms ring with system reliability. It also adds a lock window before the alarm and re-ring plus wake check after it.
Does BarLock work with any barcode?
You save a specific barcode or QR code as the mission for each alarm, and BarLock verifies the scan against exactly that code.
