Unlock Viral Success: Discover the Top 9 Social Media Contest Tools That Experts Swear By in 2025
9. Woobox
Woobox is another simple but powerful social media contest app with a great user interface.

You can use it to run all kinds of contests, from basic Facebook giveaways to photo/video voting contests, instant win games, and more.
Plus, build other types of interactive content like quizzes, polls, popups, forms, and more.
I particularly like the Hashtag Gallery feature. It allows you to curate and display the photos/videos your contest participants share by automatically pulling them in from posts with branded hashtags.
