About

Fit Principles — cut the noise, change your body. SUBSCRIPTION REQUIRED: Fit Principles requires a paid subscription (Fit Principles Pro) to access the app's features. Every plan starts with a 1-week free trial. Monthly $9.99 or Yearly $59.99. There's endless fitness information out there, and most of it doesn't matter. Fit Principles strips it down to what actually moves the needle, then makes it effortless to follow. TWO PRINCIPLES. THAT'S IT. • Fat is calories — you lose or gain it based on one thing: eating more or less than your body burns. • Muscle is protein + strain — you build it with enough protein and progressive training. ONE DAILY TARGET, BACKED BY SCIENCE Tell us your goal and your timeline, and Fit Principles calculates the exact calories and protein to hit each day — personalized to your body, not a generic formula. LOG FOOD IN SECONDS — HOWEVER YOU WANT • Voice — just say what you ate • Photo — snap your plate • Text — type it • Barcode — scan a packaged food Our AI assistant, Accountability, identifies the food and pulls accurate calories and protein, even from restaurant menus. YOUR PROGRESS, ON AUTOPILOT Connect Apple Health and your weight, body fat, and calories burned sync automatically. No manual entry, no guesswork. SEE WHERE YOU'RE HEADED Track calories, protein, weight, and lean mass over time, with projections that show your expected body and goal date. Edit or fix any day's log — today or weeks ago. Set your target. Log your food. Watch it work. — Fit Principles Pro unlocks everything with a 1-week free trial. Monthly $9.99 or Yearly $59.99 (save 50%).
