To reduce the number of users that never logout, whether looking or not even using the app, ping their phones every half hour. "Still using grindr? Yes No" The user would then have to click on yes to stay logged in. If the user did not respond, that user would be logged out by the app. Too many users that are logged in for weeks at a time! I wonder how many of them don't know that they can log our, or how to do it!
