A common (unfortunately, IMHO) way to do this is for
your app to create a small hidden prefs db that uses a
different creator id.  Then whenever your app runs, it
can check that db to see how often it has run before,
when was the last time, whatever you want to store
there.  The problem with this method, and every
strategy for limiting the number of times an app can
run, is that it wastes valuable device memory and
users get P---ed Off when they realize they have lost
that space and don't know where it went or how to get
it back.  

(Example Scenario: User installs 10 such apps, tries
them out, then deletes them.  Each leaves a 1K file
behind.  Now User has lost 10K and is not happy.)
