I was installed this app by the recommendation of my friends . But when I used it personally I really realised this is very worst app.this app usually takes the photos of your project and commbined it and save as a PDF format.but when I take the photos from it the quality of photo was very bad rather than I can take photo from my inbuilt camera app of phone.the combination of photo in caravanner take much more time as u can never expected and it takes much more memory space in your space.so it is totallwaste of storage and net downloading
