Today’s fresh Android apps may inspire you to put your fat cat on a diet, learn to say hello in Russian and German, or recreate a scene from one of your favorite TV shows.

If you’re a big fan of ABC’s hit television series LOST, you know that the numbers 4, 8, 15, 16, 23 and 42 are a major recurring theme on the show.

Lost It is an app that’s based on these numbers. Pretend you’re in the hatch and type in the secret code every 108 minutes. Either save the world every 108 minutes or suffer the consequences of the unknown.

How long do you think you can keep it going? Hours? Days? Months? Download this free app and find out.
