The description of ReachTimer: Share time left until target reached
ReachTimer let's you share your estimated time of arrival (ETA) that you need until you reach your destination with your car. The app does not require any registration. You only need to select the location you are driving to and pick a any-name that is used for sharing and is visible to your friends.
You need to pick someone up, but the person does not show up at the agreed time? Send a ReachTimer and the other person can check when you arrive.
Or is your partner waiting for you to heat up your meal but your are driving? Send a ReachTimer and your partner will know when you arrive.
