Ridiculously simple – incredibly effective
What does this app do? It displays Siemens Star and prevents your phone/tablet from going to stand-by. That’s not a whole lot you might say, but it’s an incredibly effective tool for checking focus. With one tap you’ve got a high-resolution Siemens Star at your fingertips. No bells and whistles, but a handy little app for camera operators, focus pullers and photographers. And the best part: It’s free!
