Contract Countdown is an iPhone app that helps you keep track of your sea contracts. Developed by John Phillips, this app is perfect for staff and crew working at sea. With Contract Countdown, you can input your contract's start and end dates to view your progress through time. You can also include all your previous contracts to see how many contracts you have completed and how many days you have spent onboard in total.

The app calculates your contract's total days, total days of all contracts, days complete, days remaining, percent complete, percent remaining, and total number of contracts completed. Additionally, you can calculate how many days you were onboard during a tax year by inputting the tax year start and end date and hitting 'Calculate.' The app also features a red zone at 80% complete, which is the home stretch as you run up to returning home. You can share your stats on social media with a screenshot and a custom message.
