About I'm Ok
If you're the kind of people who always worry when someone doesn't respond to your calls or your messages, and you think that something bad could've happened, I'm Ok is the solution.
With a very simple method, I'm Ok sends every few minutes, user's location to people that the user selected, so you can always see where the person you care about is.
It will keep tracking location for 60 minutes. Once 60 minutes passed, the sharing is canceled. However it can be renewed for as many times as you want.
