"Prize Management" is a unique prize management app that lets you track your sweepstakes entries and daily lucky behaviors all in one place.

[Prize Entries]
Easily record the sweepstakes you've entered. Select categories (manufacturers, convenience stores, supermarkets, etc.) and channels (postcards, online, SNS, LINE, etc.) to register. You can also record and review your wins and losses.

[Winning Probability Analysis]
Automatically analyze your winning probability by category and channel. You'll discover your unique trends, such as "supermarket sweepstakes are easier to win" or "SNS entries have a higher chance of winning than postcards."

[Break-Even Calculation]
Enter the costs of the sweepstakes (postcards, product purchases, etc.) and the prize value to calculate your break-even point. You'll know how much you're saving overall by buying eggs to enter a sweepstakes and winning a gift certificate.

[Lucky Points Feature]
Record your daily lucky behaviors as points. Small habits like waking up early, cleaning, and expressing gratitude can be visualized as points. Do you see more wins when your lucky points are higher? Let's test it with your own data.

[Free Customization]
You can add and edit all categories, channels, and lucky actions yourself. Feel free to customize it to suit your own sweepstakes style.

All data is stored locally on your device. No account registration is required, so you can start using it right away.
