Drawing Brush Free is not the most catchy title for an app, the icon is poor, but the app itself is really quite good. It offers a shed load of brush types, blenders, pencils, pens, all with variable size, opacity and consistency. It offers support for a number of active styli, layers, pinch to zoom, proper undo buttons, and uniquely in the apps I've reviewed the opportunity to plop a reference file on the page, which is a cracking idea.
The pens work well most of the time, and I really liked the look of some of the pencil marks, which felt very real, the only downside was the stylus I used would sometimes offset its tip by 5 mm or so, making line join up a bit notchy and unpredictable.
Export is to photo album, email or social media, and there's a built in recorder to capture your process.
All in all a surprising little app, with rather nice pencils.
Today's challenge was to draw a bottle, so I did a bottle of Summer time Gin
