Good app, needs lots of work
Overall it's a really solid list of features that could remove the need for 3 or 4 other photo editting apps, if you get passed the learning curve I haven't experienced any crashes or anything unusable, but the interface is extremely unintuitive. Tools aren't labelled and they constantly and randomly rearrange themselves, making them extremely confusing to use or switch between. Also, some tools have hidden features (like transparency, round/square modes, light/dark versions, and more), but they're not indicated anywhere in the app (you can only access them in the color picker menu AFTER using the tool).
