What the data shows you
Built on real, regulator-mandated ad transparency data and a multi-million-app catalog.
Working niches, not noise
Surface apps that pass every proof at once — running ads right now, monetizing via in-app purchases, and scaling in installs and reviews.
Real ad creatives
See the live Google and Meta ad creatives behind each app, pulled from the transparency centers — formats, run dates, and advertiser variants.
Whole-catalog search
Search, sort, and filter across ~3.4M iOS and Android apps with exact counts and true global ordering — powered by a columnar data lake.
Sustained spend & velocity
Rank advertisers by how long they've run ads and which niches are heating up week over week, so you build where the money already is.
Traction over time
Growth baselines track install and rating momentum, separating apps that are actually scaling from ones that merely exist.
Zombie hunter
Find low-rated apps still buying lots of ads — proven demand with a weak incumbent you can out-build.
Three moves to a validated niche
- 01
Pick a niche
Start from Tools, Productivity, Photography, or Video — or explore the entire catalog.
- 02
Filter to winners
Layer on ads-running, IAP, min installs, and growth to isolate apps that are already working.
- 03
Study the ads
Open any app to inspect its live creatives and advertiser footprint, then build your version.
One app that's running ads — in your inbox every morning
We send you a single app we caught running ads about two weeks ago that's still spending today — a real signal the campaign is working. One email, one app, no fluff.
