Great tool for grid maps – Battle Map 2 Review
There is a strange lack of snapping grid drawing tools in the App Store, and while this one is pricey, it was worth it for me. I will say it needs some tuning as it chugged down over half my iPad Pro battery in a single evening of 3.5 hours of play, so must have something scanning for input. A wider brush option would be good too. Still, this tool was almost exactly what I needed to be able to get off of the grid paper notebooks.
