The latest update to Sol: Sun Clock, the personal daylight utility and alarm clock for iPhone, now makes use of the new iPad’s hi-res screen.
As a developer, I was happy that 98% of Sol:Sun Clock’s codebase had to be changed. Very few of the graphics had to be remade for the new iPad’s hi-res screen as I’d already included the Retina graphics for the iPhone 4, and most of the graphics including stars, sun, earth, and colored daylight, twilight, and night-time areas are all drawn by code inside drawRect().
