Lemon8 is a lifestyle app by TikTok that’s giving away free gifts and gift cards through its Million-in-Air promotion—no purchase required. Simply download the Lemon8 app on your iOS or Android device, then click the promotional link and tap “Open Lemon8” to join the activity. Inside the app, tap the Get Gifts icon and choose Get Surprise Box. After joining, wait about 10 minutes (sometimes a bit longer) to open your first box, which typically includes a $5 gift card.

You can open one surprise box per day, and you can earn even more boxes or gift cards by referring friends. If you win a prize, Lemon8 will notify you through in-app direct messages with instructions on how to claim it. Be sure to enable push notifications, as prizes must be claimed within 14 days.
