Our sister site, The Sweet Setup, recently picked Wunderlist as their favorite app for shared lists. While Clear and Omnifocus were picked for other categories, Wunderlist can still be incredibly useful in conjunction.

Wunderlist was picked because it syncs fast, it’s easy to share lists, and it’s accessible from multiple platforms (web, Mac, PC, Android, etc). Wunderlist is free, but you can upgrade to a pro account for $49.99/year. The pro upgrade enables:

• Unlimited files per item
• Unlimited assigning per item
• Pro backgrounds
• Unlimited subtasks per item

It’s been updated for iOS 8 and iPhone 6, so it’s actively being developed. Get it on the App Store
