Beautiful and buggy – ProtoSketch – Graphic Design Review

One of the best featured well thought out vector drawing and design tool. However, buggy. *Close gap on pencil tool disable does not work. *Hitting undo button too quickly crashes app every time. At least the designers seem to have put in robust autosave and recovery algorithms, so it's just a frustration. *Brush tool leaves gap artifacts on tight loops and bends. This alone is almost a deal breaker since there is much work into finding workarounds. It appears that at these points, the line width is forgotten on one line when two thick lines come in contact on tight loops. It will leave an open space artifact at the center of the tight curve. *Developer needs to speed up the code because as you add objects and layers program becomes sluggish. And this is only what I found having purchased and started playing with the app for only 10 minutes! All that said, I'm sticking with it and investing my time and energy and money, because it appears the developer is committed to making this the best iOS vector software on the market and is publishing quick releases with new features and fixes! 5 stars when some of these bugs are stomped! Developer needs to do better debug before release. IOS 9.2.X on iPad Pro 128 Gig
