Designed mostly for beginners, it involves you into ASO workflow easily, from adding your application to holding a hand on pulse of what's goin' on in the competition rush. You can use Checkaso for analytics, gaining marketing insights, collecting metadata, finding smth new from another application (especially those you're competing with for traffic) and many more

Great support team, all the issues have been solved quickly 4. Great educative content in their blog, on Youtube channel, in e-mails I've subscribed at. 5.

How it works in terms of obtaining important keywords from the competition. Thanks to it, you can know keywords that were previously difficult for me to obtain. Additionally, the price is good.
