GoKawiilDarkplug app turns iPhone and smart plug into darkroom enlarger timer
A new iOS app called Darkplug lets film photographers control their enlarger via a cheap networked smart plug instead of a dedicated darkroom timer. The app offers a red-on-black interface designed to avoid fogging photo paper, plus basic straight-print timing for free, with advanced features like F-stop timing, test strips, dodge-and-burn planning and split-grade printing available through a one-time Darkplug+ purchase.
