Six offline training apps: a workout log, a powerlifting meet planner, a race fueling planner, hill-adjusted race splits, and practice journals for golf and tennis.

• Fairway Ledger ($9+): A golf journal in black lacquer and gold
• Baseline Ledger ($9+): Tally every ball of a hitting session from the keyboard, click the service box where each serve landed, count rallies with the space bar, and log matches on a broadcast-style score

No account and no subscription. Each app is a single file that runs in your browser on Windows or Mac, offline. Your data stays on your computer.

Who it's for: Lifters, runners, triathletes, golfers and tennis players who want their training log on their own computer, with no account.
