Santas Naughty or Nice List is a lifestyle app available for iPhone users. Developed by Daniel Storm, this app is designed to help parents ensure that their children stay on the nice side of Santa's list during the holiday season. It can also be used for pranks, making someone believe they have been naughty this year.

With Santas Naughty or Nice List, you can motivate your child to behave well by using the app as a tool for positive reinforcement from Santa. The app allows you to select the outcome before someone scans their finger, giving them a result that will amaze them. You can even tap the countdown label to choose a different outcome or let them try again with the same results.

In addition to its main features, Santas Naughty or Nice List also offers a countdown to Christmas, which adds to the excitement of the holiday season. The app also includes a widget that allows you to see the days until Christmas countdown right from your home screen. Furthermore, there are over 20 different holiday stickers for iMessage, allowing you to add a festive touch to your messages.

It is important to note that this app is intended for entertainment purposes only and does not provide true finger scanning functionality. Santas Naughty or Nice List is a free app available in the Lifestyle category on the App Store.
