I decided to make Advanced Camera Ruler free for a day and see how it went. To my surprise, it ended up with 23682 downloads just in one day. It did extremely well in China and many European countries. If I remember correctly, I haven’t seen this amount of downloads in any of our apps on Android, although I never made Advanced Ruler Pro free on Android. All the free versions on Android are feature-limited version of the corresponding paid version which will of course attract less people. Comparing with the sales of this app when it is not free, I decided to keep it free for a week or so, or even consider switching to ads support model. Will see.

I also decided to release a new version to translate this app to a few other languages. It is very disappointing to see some users’ comment saying the camera won’t turn on. The reason is the camera height has to be input first before the camera preview is turned on. There is a message right there on the screen but since many of the users don’t understand English, they don’t understand what it said. Other users try to aim at the object directly and hope the app will give the direct distance between the camera and the object. Many users never read instruction. No to complain as we sometimes do the same thing. I’ll just find a creative way to make it more intuitive.
