How I Find Profitable App Ideas
@gregisenberg · 42 min · ready
00:00 so the first thing I do when I'm looking for an app idea is I go to sensor tower and I look at what apps are actually making money
08:42 sensor tower gives you the download estimates the revenue estimates and you can see the trends over time
12:15 if an app is making ten thousand dollars a month or more in sensor tower that tells you there's real demand
15:33 what I like to do is cross reference what I see on tiktok with what sensor tower shows me because if something is trending on tiktok and the apps in that space are making money
22:10 don't just clone the top app that's a mistake a lot of people make you want to find the angle that's underserved
28:45 the CPI benchmark I look for is under two dollars if you can't get installs for under two dollars on tiktok the unit economics probably don't work

Cross-source synthesis

After regular search, optionally synthesize an answer from your top matching sources. Source-backed, not hallucinated.
Q: How do I use TikTok ads to validate a mobile app idea?
Answer
The repeated workflow across your sources is: find a category with proven demand via Sensor Tower, create before/after ad creatives, launch TikTok Smart+ campaigns optimized for purchases (not installs), and judge by CPI, CTR, and CPA vs LTV.
Playbook
-
Pick an app category with $10K+/month revenue in Sensor Tower
-
Create 5 before/after creative variants
-
Launch TikTok Smart+ campaign at $50/day, optimize for purchase
-
Measure: CPI < $2, CTR > 1%, CPA < LTV
-
Scale slowly if metrics hold. Kill if they don't.
Warnings
-
Don't optimize for installs if the goal is paid conversion
-
Don't scale ad budget too quickly — destabilizes performance
-
Apple payout delays can create cashflow risk
