To me it is, I love the QR codes and being able to scan them to keep track of things, makes it easy.
If you have an Iphone try the lite version and see how you like it first.
I have used other software in the past (Vyper, Degei) and so far this is my favorite, fits my needs.
ive seen the lite version but still havent been able to find a clear answer to what exactly the difference is between the lite and the regular one. do you know? lol
