&simultime final update: got split views kind of working today, but there are still a few bugs and some rough edges(sometimes crashes with complex layouts, and adding toplevel splits doesn't work). I also added audio to the timer with a little handmade alarm sound. Had a lot of fun, and if anyone wants to use the program or look at the source, I'll clean up the code and put it on github in the next few days!
Inspired by the fact that the Windows and Android Clocks only let you set one simultaneous stopwatch, SimulTime lets you have whatever clocks you want, in whatever arrangement you want.
Part of the Handmade Essentials Jam 2026.
Technical notes: app is written in C, with a 2D graphics library based on OpenGL(written before the jam) and SDL3 as a platform layer.
