Log a piece in seconds, in the numbers the sport actually uses. Enter any two of distance, time, and split — the third fills in.
A rowing log that speaks rower.
Ergbook is a manual erg logbook for people who own the machine and think in splits. No account, no feed, no connection to the erg required — you finish a piece, you log it, and the app does the arithmetic.
LOG A PIECE IN SECONDS
Enter any two of distance, time, and split; the third fills itself in. Watts come along for free. Steady state, intervals, and benchmark tests each get the shape they need — an interval set is a set of reps, not one blurred average.
THE PRs THAT DEFINE YOU
Eight named benchmarks, from the 500m to the hour. A PR counts only on an exact distance or duration, because a 2,050m row is not a 2k test. Every board row opens onto its own history, so you can see the whole arc of a piece and not just today's number.
SEE WHETHER YOU'RE GETTING FASTER
Volume by week or month against the window before it, and a split trend for any benchmark you pick. Set a weekly meters target and a time target for the piece you're chasing.
