Keep Alive does three amazing things for your Pokemon GO experience.
– It keeps your screen on whenever Pokemon GO is running.
– It can restart Pokemon GO if you exit out while you have it locked from the Keep Alive notification.
– It can dim your screen and prevent you from doing anything other than using the notification bar while you are incubating eggs or just travelling with Pokemon GO on in your bag.
