Time is of the essence and when it involves work, this app will surely help out those that work on an hourly basis. Developed by software developer InerTron Software, InerTrack will track time for different projects. This iOS app works by creating a list of clients and simply clicking the timer to start and stop the time. Projects associated with each client and hourly rates are measured to calculate the financial cost of labor. The project shows a detailed view of time, money and the days that have been billed. Edits can be made anytime, and completed projects will be sorted to the bottom of the list. Currently, InerTrak is available for 99 cents.
