Sidefeed: Trend Radar
Trend research for creators
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Trend research for YouTube creators. 12 countries, 14 categories, 6-hour rank movement — find the next video before the algorithm does.
Trend research for YouTube creators and content planners.
Compare 12-country trending and Sidefeed's own Radar analysis side by side, and find the signal for your next video. Breakouts beyond the big-channel charts, category distribution, 6-hour rank movement — curated for content planning, not casual scrolling.
■ Looking for your next topic
See what's catching on in 14 categories (Entertainment, Music, Gaming, Sports, Comedy and more), without YouTube's personalization. Pick 1–3 interests in Discover (or all 14 with Pro) to see popular videos in those categories only.
■ Reading the global market
Switch between United States, Japan, South Korea, United Kingdom, Germany, France, Australia, Canada, Switzerland, Netherlands, Sweden, and Singapore with one tap. See where your category travels and what's working in other markets.
■ Catching breakouts before the big charts do
Sidefeed Radar merges trending and all 14 category charts, then re-ranks by Radar Score — views-per-hour, engagement rate, and 6-hour rank lift. Surfaces small-channel breakouts that absolute-views rankings miss.
■ Tracking rank movement
Every trending video shows ▲N / ▼N / NEW badges for 6-hour rank change. Top Movers gathers the biggest climbers in a dedicated row.
■ Reading the category mix at a glance
A colored stacked bar shows what's dominating Trending or Radar right now — which categories own the chart, on a single line.
■ Why this video?
Tap a Discover video to see how it fits the current feed: category candidate pool, estimated response rank, and channel variety signals.
■ Your research queue (Pro)
Save inspiration with Watch Later, synced across devices via iCloud. Mute videos or block channels you don't care about so the feed matches your workflow.
