Dan Hulme posted a (deleted) answer on How do I stop Play Store from randomly opening when I'm in other apps?, mentioning an app called bURLY.
I made an app bURLy which lets you control what your phone does when an app tries to open a web link, such as to a Play Store app page. Even when other apps (such as the Play Store app) can open the link directly, it lets you preview what link will open, and create rules. You can make a rule to automatically ignore links to apps on Google Play, except when you allow it first.
However, it is no longer visible on the Play Store. Why?
