New in 2.4: paste or type a workout in your own words, review the structured sets, and save only when everything looks right.

Marble is a private workout journal built for fast logging, focused training, and clear progress.

Record weights, reps, distance, time, RPE, rest, notes, bodyweight, and supplements without an account, ads, or tracking. Your core data stays on your iPhone or iPad.

ADD A WORKOUT IN YOUR OWN WORDS

• Paste or type natural language, gym notation, multi-day Notes, or a Hevy or Strong CSV
• Let Apple Intelligence structure prose on device when available
• Review every workout, exercise match, set, date, RPE, rest, and note before saving
• Keep working with deterministic on-device parsing for notation and file imports

LOG WITHOUT LOSING YOUR FLOW

• Repeat your last set or use Save + Next for quick logging
• See personal-record targets while you enter a set
• Start and finish focused workout sessions
• Build weekly splits and reusable sprint prescriptions
• Track rest with an in-app timer, Live Activity, Dynamic Island, and rest-complete alert

UNDERSTAND YOUR PROGRESS

• Review Daily Highlights: a private evening recap of truthful same-day progress
• Track bodyweight manually or import it from Apple Health, and correct a weigh-in if a number was wrong

• Explore muscle-group, rep-range, effort, supplement, and calendar views
