Inspiring-Life Technologies has introduced Tasky 1.0 (http://www.inspiringlife.co/tasky/), a task management app for Mac OS X Yosemite and El Capitan. It’s been designed to give you dedicated sections for adding tasks for Today, Tomorrow and Next Week with a built-in calendar to add or browse tasks.
You can mark tasks as complete one by one as you accomplish them. You can also add task categories and sort them in one place.
Tasky 1.0 is available exclusively through the Mac App Store. It costs $3.99 with a 60% discount for a limited time.
