Binary Hammer's 30/30 is a timer app for people who need to get lots of things done in a short period of time. The app lets you set up several consecutive tasks and allocate the time you need to get each one done. The app keeps track of the elapsed time and will alert you when you need to finish your current task and move onto the next. It's perfect for reminding you take a 5-minute break from your work once every hour or to pace your progress through a circuit training course.
The app has a gesture-based interface that's pleasing to use. You can swipe to delete a task, touch and hold to move a task, and pinch apart to create a new one. When creating a task, you can give it a title, set the duration and choose both a custom color and icon. There is only one default notification sound that you can toggle on/off if you want. You can also choose to have your phone vibrate.
Once you have your list set up, you can drag items around on the fly to get the perfect workflow. There's also a big pause button that you can use to pause your task if something like a phone call diverts you for a few minutes. It's a simple app that allows you to jump right into your tasks and not get bogged down with the little details that often prevent you from getting things done.
The 30/30 app is available for free from the iOS App Store. It has a unique pricing scheme that lets you send money to the developer via an in-app purchase. You're not required to send money to unlock a feature as the app is fully-functional. The in-app purchase is merely an opportunity to thank Binary Hammer for its hard work.
