Forge Strength Trainer

One purchase. No subscription, no account, no cloud. New in 1.1.1: plate calculator, PR detection, session timer, and guided rest days.

Forge is a strength training, nutrition, and body composition tracker built for people who want to log their training without paying a monthly fee, signing up for an account, or handing their data to a server. Everything you log lives in a local database on your phone. There is no cloud. There is no sync. There are no ads, no analytics, and nothing to subscribe to.

One purchase. That's it.

TRAINING Build custom splits with any number of training days. Log sets with automatic rest timers (1, 3, 5, or custom minutes). Tap any set to see exactly which plates go on the bar, per side — 45, 35, 25, and 15 lb bars, with a warning when a weight isn't loadable with standard plates. Every working set is scored against your previous best with an estimated 1RM, and PRs are flagged on the spot. Warmup ramps fill in with one tap and stay out of your working-set volume. Also includes drop sets, supersets, bodyweight tracking, a catch-up queue for missed sessions, and a session timer that starts on your first completed set — not when you open the app.

WEEKLY VOLUME A live count of working sets per muscle group, each with an evidence-based target range. Bars show under-, in-, and over-range at a glance, so you can spot the under-trained area before the week is over.

NUTRITION Derives daily calorie and macro targets from body composition using Katch-McArdle BMR or Mifflin-St Jeor formulas. Includes barcode scanner via Open Food Facts, macro calculator, daily macro rings, and 14-day trend charts.

BODY Tracks weight, body fat %, lean mass, circumferences (shoulders, waist, arms, chest, quads), week-over-week deltas, and 8-week trend charts with goal progress bars.

REST DAYS Rest days aren't blank. Forge offers guided stretch and mobility holds, scoped to the muscle groups you trained in the last few days.

APPLE HEALTH (OPTIONAL, READ-ONLY) Pulls duration, average heart rate, and active calories from Apple Watch workouts.

ONE-TAP CSV EXPORT Exports measurements, food log, and set history as plain CSV files.
