Responding to my own post looking for an alternative to xScope the other day, I found QuickLens which does the crosshair feature and other goodies at a bargain 10 bucks. Looks good so far.

Working with CoreText today, I was reminded that its coordinate system is inverted from the one in iOS CoreGraphics, so you get text drawn upside down and have to mirror it to rectify. Really can’t wrap my head around why Apple hasn’t added a flag we can set to deal with this. Make it opt-in if they’re worried about compatibility.
