About Fiveby

Fiveby is a gym log that reads like a notebook and does the arithmetic for you. Start a workout, pick a lift (twelve common barbell lifts are ready, and your own exercises autocomplete from your history) and log each set as weight × reps with one tap, in kg or lb. A rest timer runs between sets and alerts you if the phone is locked. Finish and you get a summary, with a card whenever a set beats your best. Switch on 5×5 and Fiveby plans your A and B sessions, adds the next weight when you complete all five sets, and suggests a deload after three misses in a row, while the plate view shows exactly what to load on each side of the bar. Unlimited history, a chart of your top set for every lift, no account. Plato, a plate with eyes, keeps you company, and everything stays on your device.

Features

A Set in One Tap

Weight × reps, tap done. Exercises autocomplete from your own history, with twelve common barbell lifts ready from the start.

The Next Weight, Worked Out

Turn on 5×5 and Fiveby alternates sessions A and B, adds weight when all five sets are complete, and suggests a deload after three misses.

Plates per Side

Set up your own rack once and the plate view shows what to load on each side of the bar for any weight.

A Rest Timer That Reaches You

The rest ring counts down between sets and sends a local alert when time is up, even with the phone locked.

Every Session Kept

Unlimited history and a chart of your top set for every lift. Nothing expires and nothing is capped.

A Card for a New Best

When a set beats your best, the summary gives you a card with the bar drawn and the numbers on it, ready to share.
