KSafe

Whether it's food, electronics, or some other vice, we all have guilty pleasures that work way better as rewards than temptations. The KSafe lets you do just that. This electronic locking safe connects with a smartphone app that allows you to set goals that, in turn, give you access to whatever it is you've stashed away. You can set them based on activity — complete with fitness tracker integration — location, or time, making sure that you don't indulge until you've reached your goal.
