Fenn: Running Calorie Tracker

Run more, eat more that day. Fenn puts the calories you eat and the calories you burn running on one ring, on one screen. Log a meal, go for a run, and watch your food budget grow with every run. No ads. No account. Your diary is stored on your iPhone. Most apps only do half the job. Calorie counters make you import workouts from somewhere else, and running apps never ask what you ate. Fenn does both: the lime arc is what you ate, the orange arc is what your runs burned. FOOD LOGGING THAT KEEPS UP WITH YOU • Snap a photo of your meal and let Fenn recognize it • Scan a barcode to pull nutrition from Open Food Facts (coverage varies by product) • Search a built-in food catalog that works offline • Save your own recipes and log them in one tap • Quick-add calories when you don't want the detail • Meal, water and streak reminders that fit your day RUNNING, MEASURED HONESTLY • GPS run tracking with a live route map on Apple Maps • Net calories, not gross: Fenn uses the ACSM running equation and leaves out the resting burn that's already in your daily target, so it isn't counted twice • GPS noise filtering, so a phone sitting still doesn't add distance • Splits, pace, elevation and your full run history • Audio cues while Fenn is in use, plus a Live Activity on your Lock Screen • Share your route drawn over your own photo NEW: MUSCLE MAP See which muscles your runs worked, front and back. The detailed view is part of Pro. A PLAN THAT MEETS YOU WHERE YOU ARE • A weekly running plan based on your current level • Today's workout waiting on your Home Screen PROGRESS YOU CAN READ AT A GLANCE • Weight, calorie and macro trends • A weekly report, streaks and a clear calorie breakdown • A Home Screen widget with one-tap water logging WORKS WITH APPLE HEALTH Fenn reads your weight and steps and saves your runs back as workouts. THE MATH BEHIND YOUR TARGET Your daily calorie target starts from the Mifflin-St Jeor equation and your TDEE, then adjusts for your goal: lose weight, build muscle, improve endurance or stay fit. Choose more than one and Fenn combines them properly. Losing fat while building muscle is a recomposition, not a doubled deficit. PRIVATE BY DESIGN No account, no sign-up and no ads. Your diary is stored on your iPhone, and meal photos are sent only for recognition. Export everything anytime as JSON or CSV. FENN PRO Fenn is subscription-only; there is no free tier. Every plan starts with a 3-day free trial. Choose monthly or yearly, or buy lifetime once.
