Ratings and ReviewsSee All
Not a bad app! I read reviews on being able to read it and not being able to zoom. I turned my phone sideways and it makes it bigger. You can also screenshot the image and then zoom that may be a little aggravating but it works.
Useful, hopefully still relevant
First off, you can zoom!! Tap on the image and it pops up in another page and is zoomable. Linework is changing so much some of the minimum approach things and such might be outdated. But I'm sure they are still practical, good app though from the looks of it
App works great
Really good app lots of useful info well thought out. As for the small print all you have to do is tap on diagram and it opens up and you can expand to view close up.
With Family Sharing set up, up to six family members can use this app.
