Problems
Firstly, I found it very difficult to switch applications between the darklab app and the photo application with the drawing (reference) of the Tattoo I was making. The app could have a screen where I could place my reference along with the command buttons. Another thing I didn't like is the power and voltage commands being on different pages of the e-giv. Finally, the app could record the tattoo time and leave it recorded, because when the machine's battery runs out there is nowhere I can read the time information.
