Great app - But, ruler needs fixed – iHandy Carpenter Review

I’ve used this app for years and it’s been really useful. However, I’ve experienced the same issue as other reviewers. In later updates, the ruler is now wildly inaccurate and the recalibration button seems inoperable. If that issue could be fixed, this is definitely a five-star app.
