In my spare time I build widgets and data fields for Garmin smartwatches. Most of them are free, they compute everything on the watch itself, and they need neither a phone nor an account.

A race-day command panel for ultra and trail: when do I reach the next aid station, will I make the cutoff, and when to take a gel.
