I would still like to see the following enhancements: 1) setting for standard unit of length. You have to change as a mechanical engineer at jebem measure to mm. (Possibly also standard color set) 2) the whole app should be able to be operated in landscape mode. You have to be all the time turning device: Make photo - Landscape Save photo and select - hochformat Define arrowheads - Landscape Measurement value add - hochformat Etc.
One could still improve a lot in this well. Looking forward to the updates. Then the app would namely really brufstauglich and efficiently and not just a toy for hobbyists. Then there is definitely 5 star.
