Focus Chart

... especially when using an astronomical camera due to very high magnification. Really a tool, not an app, as it just provides an image. Would be much more helpful if you could print it out. Also I don't mind ads but not every time you touch anything.

Adding 2 or 3 different chart type can be good. Very useful in many situations. Please the people don't know/understand what this app do, avoid to publicly show off your ignorance on yours comments.

Focus chart; put LG 7" tablet on lightstand; camera on tripod and shot at several different f-stops and ISO settings, good camera/lens check

When u try it always ask for other apps

This is a tool not an app. It could be more functional if it could print the chart for use as a focus target. Without that it can't be used on the device it's installed on. On a phone the target is too small to be of serious use. On some phone screens it develops a Moire pattern near the center of the target which looks fuzzy in a viewfinder. Might be ok on a large tablet.

All else fails... GET YOUR EYES CHECKED!!

It's weird app,,,

good

Absolutely brilliant! Always have a focus chart in your pocket :) I can't understand why people moan about this, it works perfectly. Why would you install it if you didn't know what to do with it?

Works fine. I don't understand why posters would download it if they don't know what it's for.

Really simple pattern display to test lens resolution in a test shot. "Less is More".

If you don't know what this is for, don't comment.

Every time you touched the screen an ad would pop up.

Whenever I touch the screen an ad pops up. What does the chart do? I'm uninstalling. I agree with Carsten Thomson.

On a Verizon Galaxy Nexus. The app opens to a black screen. When I exit, the app ask if I want to preview the director app.

Wierd on the eyes

No -_-

This app just shows a picture and then an annoying pop-up every time you close it. UNINSTALLED

Very simple app. But works well

On Samsung S4, I get a Black screen and an offer to go to your other app when I back out.
