The most important Premium feature is the unlimited number of workspaces. If you like to seperate your tasks into projects, ThunderTask Premium is for you.
If you subscribe to Premium, there are absolutely no restrictions in all of our ThunderTask apps including the iPhone App. You can create as many tasks, lists and workspaces with as many teams members as you want.
You also get all future updates which will include smart lists, notes, file attachements, calendars and many more. If you pay for our software, you actively support the development of ThunderTask.
