All your fitness data in one place.
Most fitness apps only understand one slice of your routine. LifterOS brings the pieces together so you and AI can see what you did, how your body responded, and what might be driving progress.
LifterOS
AI needs
context.
What you did
Training logs and workout history
What changed
Body composition and progress photos
How you recovered
Sleep and nutrition metrics
What might explain it
Bloodwork and protocols
The point
Better inputs for better training decisions.
See what it tracks
The data AI needs to understand your training.
LifterOS does more than collect files and logs. It normalizes messy inputs into a standardized fitness record, so workouts, scans, labs, sleep, nutrition, protocols, and photos can be analyzed together instead of treated like disconnected fragments.
- Training Logs Log workouts directly from LifterOS’s built-in workout logger, and import your historical workouts from other apps.
- Body Composition Load PDFs of DEXA or InBody scans, sync from Apple Health, or manually log key body composition metrics.
- Protocols Track your whole stack in one place, with protocol history tied to the rest of your training record.
- Bloodwork Load your bloodwork results from leading providers like Labcorp and Quest.
- Sleep & Nutrition Sync data from Apple Health or manually log the key metrics that shape recovery and performance.
- Progress Photos Load your photos so AI can actually see how your body has changed over time.
How it helps
The foundation for an AI-first training protocol.
Instead of asking AI to reason from incomplete snapshots, LifterOS gives it standardized data it can compare over time: training, recovery, body composition, labs, protocols, and visual progress.
