About
Less tapping. More lifting.
Your arms are shaking. Your next set is coming. Logging your workout should be the easy part.
Big III brings a familiar AI chat experience to strength training. Type or say what you lifted, log your sets and ask your coach a question without digging through menus or filling in tiny spreadsheet cells. Built around the squat, bench press and deadlift, with Apple Intelligence for natural-language logging and personal coaching.
LOG IT LIKE YOU SAY IT
“Squat 100 kg for five.” “225 pounds for three.”
Type your set or tap the microphone and speak. Check your words before sending, log the work and let the rest timer keep you moving. Edit your log when you need to. Simple logging stays available even when Apple Intelligence isn't.
A COACH THAT KNOWS YOUR TRAINING
Ask about technique, your next set or a lift that has stopped progressing. Your AI coach uses your programme and training history as context, so you can have a conversation about your own lifting.
Coaching is powered by Apple Intelligence through Apple's Private Cloud Compute. Your programme comes from Big III's training engine; the coach helps you understand it and make informed decisions between sets.
THREE LIFTS. A PLAN FOR YOUR LEVEL.
From your first plates to heavier personal bests, build your squat, bench and deadlift with a programme based on your experience, current lifts and available training days. Main lifts, supporting exercises and progression come together in a week you can actually follow.
Life changes. Swap a training day, skip an exercise, come back to it later or choose a lighter session. Keep training without rebuilding a spreadsheet.
BUILT FOR THE GYM
• Type or dictate sets in a familiar chat interface.
• Rest timers help you stay with your session.
• Work in kilograms or pounds.
• Use Siri and Shortcuts to start a workout or see your progress.
• Review your training on iPhone and iPad, with private iCloud sync.
• No separate app account to create.
SEE WHAT YOU'VE BUILT
Follow estimated one-rep maxes, your combined Big III total, weekly training volume and your workout history. Earn plate milestones from lifts you actually complete, and work towards the 1,000 lb club. Your estimates show where you're heading; your achievements celebrate the work you've done.
TRAIN WITH YOUR RECOVERY IN MIND
Optionally connect Apple Health to see a daily readiness estimate based on available heart rate variability, resting heart rate and sleep data. Choose a lighter session when you need one. You're in control, and Health readings stay on your device.
LEARN THE LIFTS
Explore the Lab for 3D lift models, technique cues, common mistakes and accessory exercises that support your main lifts.
From the developer of Two Plates, powered by the same training engine and built for all three lifts.
