Pose Pacer
Most drawing timers are a single countdown. A real life-drawing session isn't.
It's gesture warm-ups, then longer poses, a break, more poses. Somebody has to watch the clock, and in most rooms that somebody is also trying to draw. Pose Pacer lets you build the whole session ahead of time, one timed step at a time. Hit Start and it calls out each pose, dings at the end and moves on by itself, even with the phone locked.
My own iPhone app, designed and built from scratch, and on the App Store. A browser version is on its way at lifedrawingtimer.com.
