Feature

QR code alarm app for iPhone

BarLock can use a QR code as the physical key that dismisses a protected iPhone alarm.

For routines where a printed code is easier than using an existing product barcode.

BarLock mission step with a saved barcode code

Why it fits

Make dismissal prove movement.

A QR code can live exactly where you want the alarm to end: by the sink, desk, coffee area, workout gear, or door.

The problem

A checkpoint you can print

Product barcodes are convenient, but they have opinions about where they live. The toothpaste moves, the coffee bag gets recycled, the label wraps around a curve that scans poorly in dim light. A printed QR code has none of those problems: it is flat, high contrast, and it stays exactly where you taped it.

That makes QR codes the flexible option for alarm placement. Print one for the bathroom mirror, one for the kitchen, one for the front door, and point different alarms at different codes. Weekday alarms can end at the coffee grinder while the Saturday-run alarm ends at the shoe rack.

Any QR code works as long as it scans reliably, so test it once where it hangs: same wall, same morning light. BarLock verifies the scan against the exact code saved for that alarm, so a random code on a roommate's cereal box will not end the mission early.
