The H Box is pleased to announce the release of “? Day” for iPhone and iTouch devices. This handy productivity app provides users with a simple way to look up what day of the week it is now, what day of the week a chosen date falls on, and to calculate the difference between days. It will also indicate dates at the start or end of a set number of days, such as the start and end of a 30-day trial period, or how long it has been since something happened. It’s easy to look at, easy to use, and saves people time.
