Happy Measure 3D Ruler

★★★★★ Intuitive and useful Very intuitive: I was measuring and placing things within 5 minutes of printing the marker. The smiley/frowny face marker detection indicator has rapid mood swings with my phone's camera, which made me think it was very sensitive to hand jitter, but when I followed the hint to press and hold the face to adjust to lighting conditions it worked fine and I always could eventually capture. It would be fun to be able to re-scale the object after capture: place tiny copies of yourself running from your cat, or scale up your TV, etc. The application closed for some reason when either I or the phone automatically dimmed the screen to save power, which was annoying -- most other apps persist unless manually closed by me. Maybe this is a setting I haven't discovered yet or a behavior specific to my phone (Motorola Photon). I'd really like a way to define more complicated 3D shapes within the capture box, so that non-boxed shaped things could be manipulated without background duplication artifacts -- maybe some option to auto-hull to the object? Seems like it should be possible if enough views are captured and if the object stands out from the background enough. Neat app overall!

★★☆☆☆ Great concept, but not really working yet The developer has a lot more work to do on the bug fixes. This can be an awesome app if they make it work.

★★☆☆☆ Needs to specifically support Samsung Galaxy S4 The app has potential, but the developers need to correct the extreme distortion on the galaxy S4 camera. (Or give calibration instructions) The pattern had to be very close to the camera to be recognized. No auto focus. Doesn't take advantage of camera's high resolution. I'm looking forward to an update. Thanks!

★★☆☆☆ Where do I get the marker? Well I don't know where to get the marker.. It's not in the overview or on their website? At least put a link to it in the overview.

★★☆☆☆ HTC EVO LTE app don't work
