When it comes to tracking tasks on the iPhone I just don’t get it. Why doesn’t Apple provide a built-in task tracking application on the iPhone that syncs with popular PIM applications on the computer? Developing such an application not only sounds easy, but is almost a requirement on any modern-day mobile PDA-like device. Luckily third-party software developers have picked up the pieces Apple left behind by providing a wide range of task tracking applications available through Apple’s iTunes based App Store. Out of the numerous selection my favorite is Zenbe Lists due to its high polish, reliable web-based syncing, and optional horizontal layout.
