iOS 17.0+ Β· iPhone Β· iPad Β· Free with Pro Β· EN Β· KO Β· JA12-country trend research
Compare public YouTube trends across the United States, Japan, South Korea, United Kingdom, Germany, France, Australia, Canada, Switzerland, Netherlands, Sweden, and Singapore.
Radar Score + 6-hour movement
Find breakouts by views-per-hour, engagement rate, and rank lift β not only absolute view count.
14 categories, no personal feed bias
Research Entertainment, Music, Gaming, Sports, Comedy, Science, Fashion, and more without training your own YouTube recommendations.
Find the next video before the algorithm does
YouTube is great at showing what each viewer already likes. Sidefeed is built for the other job: seeing what is moving across countries and categories before it becomes obvious.
Use it as a lightweight research desk for video ideas, content planning, competitor scanning, and market intuition.
What Sidefeed Shows
Signal | Why it matters |
12-country Trending | See what different markets are watching without switching accounts or regions. |
14 category feeds | Research Gaming, Music, Comedy, Sports, Science, Fashion, and more. |
6-hour rank movement | Spot videos climbing fast instead of only videos that are already huge. |
Top Movers | Surface the biggest upward jumps in a dedicated row. |
Radar Score | Re-rank videos by velocity and engagement to catch smaller-channel breakouts. |
Top Movers.
The movement screen separates videos that are rising quickly from videos that are merely already large, so topic research starts with momentum.
Radar analysis.
Radar turns the feed into a research list by combining views-per-hour, engagement rate, and rank lift into a single scan-friendly score.
Developer note
Sidefeed is not meant to replace YouTube. It is a research layer above public trend data: a way to compare countries, categories, and momentum without changing your own recommendation feed.
No Google login required. Videos open in YouTube, and the app is designed for research rather than personal feed tracking.
