Strength, crafted.
The AI strength training app, built around your goal.
Build muscle, get stronger, or get toned — Liftcraft helps you get the right program and tracks every set on iPhone and Apple Watch.
No spam. We'll email you when iOS is ready.
Built around your goal.
An AI strength training app that adapts to what you're training for. Build muscle, get stronger, get toned, or train around an injury — Liftcraft helps you get the right program. Or bring your own from ChatGPT or Claude. Or pick a proven program from our library.
Three ways in. One engine.
However you train, Liftcraft tracks it.
Start from your goal
Tell Liftcraft what you're training for — fat loss, muscle, strength, or training around an injury. We build the right program for your experience, equipment, and schedule.
Pick a proven program
Start with a battle-tested program from our library — beginner linear progression, classic wave loading, powerlifting schedules, hypertrophy templates. Pick, follow, track. Switch any cycle.
Bring your own from ChatGPT or Claude
Use our prompt template with ChatGPT, Claude, Gemini, or any AI. Paste the result back into Liftcraft. We validate it and start tracking. Power users can connect Claude or ChatGPT directly via MCP.
Built differently
Adapts to your goal.
Weight loss programs don't look like strength programs. Injury-accommodating programs don't look like hypertrophy blocks. Liftcraft builds what fits your actual target.
Any program works.
Beginner linear progression, 5/3/1, wave loading, hypertrophy blocks — Liftcraft is agnostic. Switch at any cycle.
AI-friendly, not AI-led.
Use ChatGPT or Claude to design your program if you want. Liftcraft is where you execute it — with or without the AI.
Questions
What is Liftcraft?+
Liftcraft is an AI strength training app for iPhone and Apple Watch that adapts to your goal. Tell Liftcraft what you're training for — building muscle, getting stronger, getting toned, building core strength, or training around an injury — and it helps you get the right program. You can also pick from a curated library of proven programs, or bring your own from ChatGPT, Claude, or a coach.
What goals does Liftcraft support?+
Liftcraft builds programs around the goals people actually train for: building muscle, getting stronger, getting toned, building core strength, and training around injuries like lower back pain. Each goal gets a methodology that fits the target — hypertrophy blocks for muscle, strength waves for strength, higher-rep volume work for toning, lumbar-aware programming for back issues.
What programs does Liftcraft support?+
Liftcraft works with any structured strength program. The library includes classic wave-based progression, beginner linear progression, powerlifting schedules, hypertrophy templates, and 3-day full-body splits. You can also import custom programs from any source — including programs you design with ChatGPT, Claude, or another AI.
Is Liftcraft free?+
Liftcraft is free for the core experience — pick a program, log your workouts, track your PRs and progress on iPhone and Apple Watch. Advanced features like unlimited AI program generation and premium templates will be paid later. Early-access members get extended free access to those features when they ship.
When is Liftcraft available?+
Liftcraft is currently in private beta on iPhone and Apple Watch. Public launch is scheduled for 2026. Request early access above to join the beta now — invitations roll out as we expand the user base.
Can I use ChatGPT or Claude to create a workout in Liftcraft?+
Yes. Liftcraft provides a prompt template you can paste into ChatGPT, Claude, Gemini, or any AI. The AI generates a structured program, you paste it back into Liftcraft, and our validators check it against safe volume and exercise-library rules before it becomes your next cycle.
What is MCP and do I need it?+
MCP (Model Context Protocol) is Anthropic's standard for connecting AI tools to external data. Liftcraft's MCP server lets Claude Desktop or ChatGPT directly build programs in your account. Most users won't need it — you can simply pick a premade program from the library or paste output from ChatGPT or Claude.
Does Liftcraft work with Apple Watch?+
Yes. Liftcraft has a dedicated Apple Watch app for logging sets, viewing today's workout, and tracking rest timers. It syncs to iPhone and the web automatically.
Who is Liftcraft for?+
Liftcraft is for anyone who wants to get stronger, leaner, more muscular, or more capable — with a program that actually fits their goal. Beginners get a clean linear progression. Intermediate lifters get real methodology. Advanced lifters can bring their own or connect AI tools.
