01 / NO CLOUD
Your data stays on your phone.
Local SQLite. No accounts. No syncing. No analytics. Nothing leaves the device.
Lifts, macros, and measurements in one app — built for people who want to track their training without paying a monthly fee or fighting a clunky interface. Zero accounts, zero subscriptions, zero data leaving your phone.
Local SQLite. No accounts. No syncing. No analytics. Nothing leaves the device.
Skipped a session earlier in the week? Forge surfaces what you missed, with urgency indicators so you know what to make up.
Free on TestFlight. Source on GitHub. Run it from your own machine if you want.
Build your own routine — any number of training days, any focus labels, any exercises. Tap a set, log it, the rest timer starts.
Every exercise opens with a "Beat this" card and a sparkline of past sessions. Tap a set complete and the rest timer auto-starts so you stay in the flow.
Forge derives your daily targets from your own body comp — no spreadsheet, no online TDEE calculator, no "average male" estimates. Switch your phase and the numbers move with you.
When your body fat % is logged, Forge uses Katch-McArdle (lean-mass-based BMR — the most accurate formula for lifters) and falls back to Mifflin-St Jeor when only height and DOB are set. TDEE = BMR × your activity level. Phase delta layered on top.
Weight, body fat, lean mass, and circumferences. Goal progress bars track you toward your targets, week-over-week deltas show momentum, and an optional shoulder-to-waist ratio card surfaces the 1.618 target if you care about it.
Most apps stop at the bathroom-scale weight. Forge tracks lean mass (auto-derived from body fat %), every circumference that matters, and shows you week-over-week deltas so you can tell whether the work is working.
Finish a session and Forge pulls duration, average heart rate, and active calories from the workout your Apple Watch already recorded. Read-only access. No background tracking, no continuous polling — Forge only reads when you tap "Finish".
Most fitness apps want you to sign up, hand over your email, and let them store every weigh-in on their servers. Forge does the opposite. Everything you log lives on your phone — and only on your phone.
No account to create. No password to remember. No "we'll just keep this for analytics." No data breach can leak something that was never sent.
And when you want it back, it's right there.
One tap exports everything you've ever logged as plain spreadsheet
files — your workouts, your meals, your measurements. Open them in
Numbers, send them to your coach, archive them on your laptop.
They're yours.
Forge is open source. If you can read TypeScript, you can verify every claim on this page.
Really. Open the app and start logging. There's nothing to sign up for and no email to enter.
Your data is in a local SQLite file. iCloud's standard device backup includes app data, so a normal restore brings everything back. There is no Forge-run cloud.
Yes. Apple Health is optional — without it the post-session summary just shows sets and volume. Heart rate and calories appear when a watch is connected.
Yes. The Plan editor lets you choose which days are training days, name each day's focus, and add or remove exercises. PPL, upper/lower, full-body, bro split — whatever works for you.
