The bottom line
Check what the top apps in your niche earn, using free tools like App Annie and Sensor Tower, before you build. If the leaders make hundreds of thousands to millions per month, the market has room for you.
Key takeaways
- Top grossing charts show which app categories make money. 1:38
- The charts count in-app purchases and subscriptions, not ad revenue, because Apple and App Annie have no access to ad data.
- Netflix, Pandora, dating apps and Candy Crush style games sit at the top, and health and fitness is led by Calm and Headspace.
- Search traffic for your keyword shows whether people want the app. 3:37
- In Sensor Tower, a traffic score above 5 counts as decent. "Celebrity voice changer" scores 6.5.
- The revenue of the top five or six apps shows how big the market is. 4:07
- The top celebrity voice changer app made about $2 million in July 2018. Sensor Tower estimates are accurate to within 20 to 30 percent.
- In meditation, Calm makes $3 million, Headspace $2 million and Simple Habit $300,000.
- Aggressive subscriptions usually drive the biggest revenue numbers. 5:41
- Download the leading app and see how it monetizes. The store listing confirmed the voice changer app is subscription based.
- A weak lower-ranked app tells you which niches to avoid. 8:49
- Sleep Cycle makes about $500,000 a month, but Sleep Easy, ranked 99th, makes under $5,000.
- In the voice changer niche the revenue also drops from $2 million to a few thousand dollars after the leader.
If the top players are making hundreds of thousands, if not millions of dollars per month, then there's definitely room for you.

- The weakest ranked app shows what a failed entry looks like. 8:38

- List the keywords that fit the app and check their search traffic.
