What our customers are saying:
"Best Date Calculator in the market - Period. I have tested about 30 different time calculators on the App Store and none of them come even close. This application is fantastic in so many ways...In a nutshell, this is the best software available for date calculations and frankly this App should be at the very top of results and not at the bottom. It took me days of flipping through tons of crappy applications to find this jewel."
"I use Time Jump for construction planning and scheduling. It quickly and easily helps find durations between 2 dates...Best part is Time Jump lets you select national and state holidays, and then select if they are work days or not. You can also select 5-day or 6-day work weeks - very helpful...Great support from the developers as well...I definitely recommend this app."
"I need to be able to calculate dates using different criteria (i.e. days, business days, business days excluding holidays). To date (pun intended) none of the other date calculators I’ve tried have come even close to the functions and simplicity of this app. This is a fantastic app that is a bargain at the price, and it really should be at the top of the app store ratings."
"This app lets you perform pretty sophisticated date calculations, and the dual-calendar layout and indications of holidays makes it easy to figure out what is going on. Time Jump is now my go-to app for date calculations on the iPhone."
"Ever wonder how many days between two dates, or wonder when 90 business days from today is? Project managers will love this app because it quickly and easily calculates this information and more, making it a necessary tool in the PM's toolbox for sure."
"This is a fantastic app. With so many uses in business and my personal life, the app clearly identifies deadline dates and helps in future planning. So glad I found Time Jump!"
"Great tool for any date calculations. Very intuitive interface and beautiful presentation of the calendars."
"The app is a very practical tool for any personal or professional project management activity. I use it while planning and managing internal audits at a large multinational bank."
