I have been using Logos Weights and Measures for work on a Bible translation. I have found it very helpful but at times a little frustrating. As an example, is the diagrams that help one visualise biblical quantities. In 90% of the cases, these are excellent, but there are also a few that fail to convey the sizes properly. A case in point is 1 ephah of flour. The app shows milk gallons and soccer balls, but neither of these really helps one to picture an ephah of flour. I thought I would raise this issue because it has been of relevance to me. Please see my attachment.
