Snap Draw Iso

I was looking for an app to draw crease pattern for triangular grids. This is perfect but it keeps closing and I lose all of my progress due to it. The app is up to date but I don’t know how to get the app to stop closing its self out I just downloaded it and spent around 30 minutes on it. It closed out like 3 times. I think the closing has to do with the app it’s self. Please fix this bug. I’m giving this app 4 stars mainly because it was the app I was looking for and I couldn’t find any other app, that I needed for origami designs. I didn’t put in 5 stars because the app keeps closing. If it didn’t keep closing then it would have been 5 stars. Please fix this bug as soon as you read this.

I mean let’s get the cons out of the way, the ui is kinda silly and I’d like to be able to draw pure pixel lines instead of these ones that get flattened to bmp and end up being a bunch of extra px. Also it keeps crashing randomly. I also wish I could pay to get rid of ads. Otherwise this app is great with tons of functions! I highly recommend it even if it’s a bit tricky to get the ui down!!

App needs further development. Not bad for start up ISO drawings. I will review the app again after a few more uses
