I was thinking of this as a way to time intervals during workouts, or for phone-free timing in the sauna.
I designed it for a belt holder, but then I realized I would never let anyone see this in public!

Questions
How big is the GymTimer PCB?
It measures 25.8 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the GymTimer use?
10 parts, built around the PIC12F1571-I/P. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the GymTimer KiCad files?
From the tedfernau/GymTimer repository on GitHub, at the commit this page was made from: the board is pcb/GymTimer.kicad_pcb and its schematic pcb/GymTimer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GymTimer design in my own project?
Its repository states no licence, so its author keeps all rights: ask tedfernau before reusing the design.
