Every rep, every split, one place.
Athlyze is a standalone performance log for any sport — running, swimming, cycling, lifting, basketball, football, tennis or anything else you train for. Log a metric, and Athlyze tracks your personal bests and charts your trend automatically. Everything is stored locally in this browser — no account, no server, nothing leaves your device.
Log a performance entry
Pick a sport and a metric — presets are pre-filled with sensible units, or choose "Custom metric" for anything not listed.
Personal bests
One card per sport + metric you've logged, with the best value on record and how many times you've logged it.
Progress over time
Pick a sport + metric you've logged more than once to see the trend line and the computed improvement since your first entry.
Log at least two entries for the same sport and metric to see a trend.
