LeanFifty: Calorie & Protein

Get Lean. Stay Strong.

LeanFifty is the calorie and protein tracker built for people 40 and over — when metabolism slows, muscle matters more, and you don't have time to fight a clunky app. Log your meals in seconds, hit a protein target that's right for your body, and see honest progress.

WHY LEANFIFTY

• Log in ~5 seconds. Snap a photo of your plate and our AI recognizes the foods and estimates calories and protein — or just tell the assistant what you ate in plain language ("two eggs and a black coffee"). No barcode scanning, no endless database searching.

• Protein-first. After 40, protein protects your muscle while you lose fat. LeanFifty sets a personalized calorie AND protein target using your age, sex, height, weight, and activity — and tracks both, every day.

• Honest, not noisy. A clean daily view shows exactly what you have left. Weekly and monthly trends show whether you're actually on track — no vanity streaks.

FEATURES

• AI photo logging — point your camera at a meal, review, and add • Chat logging — type a meal in normal words and confirm • Personalized calorie + protein targets (Mifflin–St Jeor, evidence-based) • Apple Health sync — steps, active energy, and weight • Weight and step tracking with trends • Curated, goal-aligned meal plans across world cuisines (vegan + vegetarian options) • A recipe library you can browse and contribute to • Simple, distraction-free design with a focus on the two numbers that matter
