About Lift Fuel AI
LiftFuel AI intelligently integrates your training and nutrition into one unified system — built for lifters who are past the beginner phase and ready to train smarter. Train with intelligence, not guesswork. LiftFuel AI analyzes your workouts, nutrition, sleep, and recovery to give you a daily readiness score so you always know if it's time to push hard or dial it back. The app tracks fatigue across every muscle group and automatically detects whether you're in a hypertrophy, strength, peaking, or deload phase — adjusting its recommendations accordingly. Nutrition that adapts to your training. Log meals with a barcode scanner, search a massive food database with 6M+ foods, or build custom recipes and meal templates. Your protein and calorie targets aren't static — they shift based on your actual training volume, body weight trends, and goals. The app even correlates what you eat with how you perform, so you can see exactly how yesterday's nutrition affected today's session. See what's actually working. LiftFuel AI connects the dots between your training and nutrition data to surface insights you'd never catch on your own. It flags anomalies in your weight, volume, and intake. It detects your PRs automatically. And every week you get a digest breaking down your progress compared to the week before. Track everything that matters. Log body measurements, take progress photos tagged by pose, monitor your weight trends, and watch your strength curve over time. Widgets on your home screen keep your macros, readiness score, and streaks visible at a glance. Built to keep you consistent. A training streak counter rewards you for showing up. HealthKit integration pulls in your steps, sleep, and weight automatically. LiftFuel AI is a subscription app. Full access to every feature requires an auto-renewable LiftFuel AI Premium subscription.
