Hitting the snooze button on an alarm clock app is too easy. In order for Puzzle Alarm Clock to stop beeping, users need to solve a puzzle, or physically get up to an NFC tag or QR code.

To get even more of a start on the day, try placing the NFC tag right next to your washroom sink so you can get straight to freshening up in the morning.

Afterward, users can simply tap their phone against the NFC tag or scan the QR code to connect to the network.

Users can save text, links, details, GPS locations, addresses, configured Bluetooth connections and more.
