passkeys

A new open-source project called openGym, published by developer DuarteSantos8, is drawing interest online. The JavaScript tool lets gym-goers self-host their own workout tracker: planning routines, logging sets, supersets and cardio, and visualising which muscles are trained, fatigued or detraining. It supports imports from popular apps like FitNotes, Strong and Hevy, plus passkey login, appealing to users who want their fitness data on their own server.
