Stop asking "what's the best ASO tool" - you're comparing the wrong things
Every month someone asks for the "best ASO tool" and the thread turns into a mess because everyone is solving different problems and calling them the same thing.
There is no single "best ASO tool" because ASO is not one job. It is at least five:
1. Keyword and listing optimization You are finding keyword opportunities, testing listings, and checking competitor creatives. AppTweak, Sensor Tower, and App Radar can all help here, but they are not interchangeable.
2. Market intelligence and reporting You are tracking category trends, competitor launches, market share, and download estimates. That is closer to data.ai or Appfigures territory. Totally different job.
3. Ratings and reviews workflow You are triaging negative reviews, responding to feedback, and tracking sentiment trends. A lot of teams try to force Zendesk or Intercom into this. That is not keyword research. Purpose-built tools like AppFollow, Appbot, and Intercom's review module handle this better. (Disclosure: I work on AppFollow, but the principle holds - review management is a separate workflow from keyword planning.)
4. Store Connect and Play Console reporting You are pulling raw analytics from App Store Connect or Google Play Console. Some paid tools mostly wrap this. Some add context. Worth knowing which one you are buying.
5. Competitor monitoring You are watching version releases, feature changes, screenshots, metadata, and creative changes. MobileAction and similar tools can be useful here, but again, this is not the same job as keyword planning.
Most comparison threads mix two or three of these together, call all of them "ASO tools," and then declare a winner. It is like asking "what is the best marketing software?" and getting answers that mix email, analytics, CRM, and helpdesk tools.
So what are you actually trying to solve right now: keywords, exec reporting, review sentiment, store analytics, or competitive intel? Because the answer changes completely.
