About SideRadar

Most app ideas fail before the first line of code, because nobody checked whether people search for them, pay for them or already have ten good answers. SideRadar checks, for every niche it can find in the App Store and Google Play, every night.

It is built for people who make apps on their own or in small teams: a way to choose what to build from what the stores show, and then to keep an eye on the rivals — and on your own app once it is out.

The numbers come from public store data and our own discovery, scored the same way for every niche. Where a number is an estimate, the page says so. How we score explains the method and its limits.

SideRadar is an independent product of Pull House LLC, a small software company in the United States. It is not affiliated with Apple or Google.

Questions, corrections, a niche that looks wrong: support@pull.house. A person reads every message.
