This app has it all. Calendar sync from your iCal, task management and the greatest sync software to date. When I delete a task in the iMac app, it takes less than on second to show on all other devices, including apple watch. I use the GTD plqtform and it seems that this app was buil for just that. Yes, it is a tad pricey, but no more than Fantastical and all of the other apps that cannot hold a candle to this one. Simply amazing.
