Forge: Lift Tracker
Gym log with next-set targets
Only for iPhone
Free · In‑App Purchases
iPhone
A new look with the iPhone tab bar and the new glass design, text that scales with your settings, landscape, and iPhone Duo support. Your workouts carry over.
Forge is a workout log that tells you what to lift next time.
Log your sets in a quick table. Forge looks at what you did and works out the weight and reps for your next session, using weights you can actually put on the bar. Every target comes with a one-line reason, so you always know why it went up, held or eased off.
LOG FAST
• One tap to tick a set. Last session's numbers are already filled in.
• Warm-up, drop and failure sets, notes per exercise and a rest timer that keeps running in the background.
• Plate math under every barbell set: "80 kg = bar + 25 + 5 each side".
• A typo can't become a record: Forge asks before logging a weight far above your best.
• Start from a routine or an empty workout. Swap or add exercises mid-session.
• About 350 exercises with illustrations, plus your own custom exercises.
KNOW WHAT'S NEXT (FORGE PRO)
• Targets follow double progression: add reps across your range, then add weight.
• Steps match your equipment. Forge learns which plates, dumbbells and machine pins your gym has, and never suggests a weight you can't load.
• Bodyweight moves count. Pull-ups and dips get rep targets, and your body weight goes into their volume and estimated 1RM.
• Planned deload weeks, and a heads-up when a lift has stalled, with options like a new rep range or a swap.
SEE YOUR WEEK
• A front and back muscle map shaded by hard sets in the last 7 days.
• Main muscles count a full set, helpers count half, warm-ups don't count.
• Personal records for every lift, and estimated 1RM trends with Pro.
ROUTINES
• Start from Full Body, Upper / Lower or Push Pull Legs, or build your own.
• Set the rep range, rest and progression for each exercise.
• Editing or deleting a routine never touches your history.
YOUR DATA
• No account and no sign-up.
• Workouts sync through your own iCloud account, so a new iPhone picks up where you left off.
• Everything works offline.
• Saves workouts to Apple Health if you allow it.
• Export everything as JSON, or delete it all from Profile.
FREE AND PRO
Logging, history, records, routines, templates, custom exercises, the rest timer, plate math, the weekly muscle map and iCloud sync are free.
Forge Pro adds the next-session targets and their reasons, deload weeks and stall alerts, where each muscle's sets came from, and strength trends. Pro is $9.99 a month or $59.99 a year, with a 2-week free trial for new subscribers. Payment is charged to your Apple ID. The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in Settings > your name > Subscriptions.
WHAT CHANGED IN 2.0
Forge no longer uses AI. Programs come from templates or from you, and targets come from fixed rules that run on your iPhone.
NOT MEDICAL ADVICE
Forge is a training log, not a medical device. Check with a doctor before starting a new program, especially if you have an injury or a medical condition.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
A new look, built for every screen.
• Forge now uses the standard iPhone tab bar, with the new glass look on iOS 26.
• Workout has its own tab. Start an empty workout or a routine from there. While a workout runs, it sits just above the tab bar; tap it to go back.
• Text follows your iPhone's text size, up to the largest sizes.
• Forge works in landscape.
• Ready for iPhone Duo: the outer screen, the open screen and Split View.
• The log reopens near where you left off.
• Fixed: the progress chip could say "Same" while the sets were planned with an extra rep.
• Fixed: a rare crash when discarding a workout.
