I have created an app which is basicly a tool for some other trademarked product. Because I want users looking for an app like this to know what is it for, I would like to use the trademarked name of the product as part of the app title, for example: "Product name tool". Also I would like to use the trademarked name in the description of the app a few times (Keyword search optimization) but I would put something like "App is not affiliated with Product name" in short description and in both top and bottom of long description.
Could this cause a trademark infringement or some other problems?
