Lucky Day, developed by Stichting de Nationale Sporttotalisator, is a free lottery app available on iPhone. With this app, you can easily use your purchased lottery tickets and check their status through a scan function. You can also view the drawing results from the past months.

The app requires a Dutch Lottery account login to access your account information and drawings. Lucky Day is only available to players who are 18 years old and above. The app is licensed by the Kansspelautoriteit, which is the Dutch gambling authority.

Overall, Lucky Day is a convenient and accessible way to participate in the Dutch Lottery. The app's scan function makes it easy to check your lottery tickets, and the ability to view past drawing results is a helpful feature. The requirement for a Dutch Lottery account login may limit its accessibility to some users, but it is a necessary step to ensure the legality of the lottery.
