Trendoline – Video Challenges
Duel friends, vote & go viral
Only for iPhone
Free
iPhone
Trendoline turns any moment into a challenge the whole world can join.
Pick a prompt. Record your 10-second take. Let the community vote. The best clips rise to the top, the leaderboard heats up, and the duels get personal.
This is not a feed you scroll past. It is a competition you star in.
WHAT YOU CAN DO
- Take on challenges: a fast, full-screen feed of real people nailing the same prompt. Swipe up for the next one.
- Record your take: a built-in camera with beauty filters, trim, text, stickers, and sound. No editing skills needed.
- Get voted: every entry competes. Earn votes, climb the leaderboard, and watch your rank rise.
- Go head-to-head: challenge a friend to a live duel and settle it. They get 24 hours to step up.
- Get invited, jump straight in: tap a friend's shared challenge and you land right on it, ready to record.
- Build your crew: follow, comment, and message the people you compete with.
- In your language: Trendoline speaks 35+ languages.
WHY PEOPLE LOVE IT
Trendoline rewards your take, not your follower count. A brand-new creator can top a challenge if the votes say so. Every prompt is a fresh shot at the top.
Create a challenge, join one, or just watch and vote. Your move.
Trendoline is for ages 13+. Every upload is moderated, and you can report or block anytime. Operated by Stairtup Labs, LLC.
