I have the premium version. I had been using Wunderlist. The most amazing Todo app ever and very intuitive. Tick Tick has worked well as Wunderlist is no longer supported. However some key things I truly miss. Push notifications when someone texts within the app. Notification that someone else has updated or completed a task or list. Copy and paste everything I need into a section as a single item in the list instead of everything becoming its own item in a list.
