This app has been invaluable to my fabrication endeavors until I updated to newer Android phone. Now I get an Android notice that it was designed for an older version and may not work. Please help. Thanks in advance, A dedicated user.

One of my most referenced apps! I have an OLD DoAll tap chart that has multi columns that I love (look by number type, not frac/dec/thread in same column) and this chart us same. Awesome!
