Keyword spy is used to identifying keywords of your competitor apps. With the help of this tool, you can study competitors' keywords and get new ideas for the optimization strategy for your own app.
To check the keywords your competitor app is ranking for, there is no need to add this app into your account. Just type the name of the app in the search box and you'll get the list of the most ranking keywords of the app.
The keywords highlighted blue already added to your collection. To add a new keyword to your collection to monitor, simply click on that keyword. Or use an option to add all discovered keywords by click on '+Track all keywords'.
It is possible to run keywords research by store and by different countries by applying the filters.
