Yes it saves liftdata.json and it show values correctly in text format when I open it with notepad, but image LiftGraph.png show 12kb size and 800x750 pix, but when the file is opened it is empty, there is no image, the opened image shows as a transparent rectangle. A simple solution for now is just a screenshot, but probably there is a bug in code, because same problem on phone and pc when image is saved.
Another small detail that would be convenient is the possibility to change not only the lift interval but also the maximum lift and maximum flow values on the graph in the configuration. Now the graph looks out of proportion with the maximum 1000cfm when measuring for example up to 350cfm.
