Been using Harvest for years, and the app was a huge welcomed bonus. Its perfect for keeping things updated and live within projects.
Flaw: still no creation of an invoice!!! How is it this still wont allow you to create one? Sure going online lets me, in desktop mode via cell or just on a the laptop but I need it in-app. Add this and harvest is unstoppable.
