Ergbook is a manual erg logbook for people who own the machine and think in splits. Enter any two of distance, time, and split — the third fills itself in, and watts come along for free.
Eight named benchmarks from the 500m to the hour, with PRs that count only on an exact distance or duration. Volume by week or month, split trends for any piece you are chasing, and no account or connection to the erg required.
