On May 19, 2014, Simplex Solutions Inc. released new To Do Checklist for iPhone and iPad. To Do Checklist offers the most effective way not only to keep your tasks in one easy-to-use app but to share tasks with friends and colleagues, using convenient on-time and location-dependent reminders. As an example, you can create a task with location-dependent reminder and share it with your friend to buy some snacks. When he approaches the assigned shop area, the on-location reminder will go off.
Aside from the highly beneficial task sharing and location-dependent reminder options, To Do Checklist offers ability to create tasks and task lists and synchronize them between all user devices.
