Trendoline: Video Challenges

Stairtup Labs, LLC

About this app

One challenge. Every take. The crowd decides.

Trendoline turns short-form video into a competition you can start, enter, and shape. Create a video challenge, post your take, invite others, and watch the leaderboard move with every vote.

Start the Challenge

Turn any idea into a challenge—dance, comedy, talent, sports, style, food, reactions, or something only your friends would understand. Set the idea, post the first video, and open the competition.

Take Your Shot

Join a challenge with your own version. Do it better, differently, or completely your way. Every response enters the same video challenge, so the competition stays clear and every take can be compared.

Let the Crowd Decide

Watch the entries, vote for the takes that stand out, and follow the rankings as the challenge unfolds. On Trendoline, people do more than react to the feed—they shape the result.

Face a Friend

Start a one-on-one video duel and put two takes head-to-head. The community decides which one rises.

Make the Next Trend

Every challenge is a fresh arena. You don’t need to arrive with the biggest following; you need a take worth watching.

Start the challenge. Take your shot. Let the crowd decide.

What’s new

Uploads now reliably resume after interruptions. Sponsored challenges now have a clearer prize-and-sponsor bar and fully localized official rules, with improved support for long names, larger text, and right-to-left languages.
