## What is Fenn?

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. Monthly and yearly plans renew automatically unless you cancel at least 24 hours before the current period ends. Manage or cancel anytime in Settings > [your name] > Subscriptions.

Fenn is a tracking tool, not a medical device, and its numbers are estimates. Talk to a doctor or registered dietitian before making big changes to your diet or training.

## Version history (last 4 releases)

### 1.7.0 — 2026-09-28

• New muscle map: see which muscles your runs worked
• A fresh, faster onboarding
• Route maps now use Apple Maps
• Apple Health fixes: watch workouts are no longer counted twice, and weight syncs correctly
• Faster, more consistent numbers across the app, widget and Live Activity

### 1.6.1 — 2026-09-23

New: rate Fenn whenever you like from Profile ▸ Settings ▸ About Fenn ▸ Rate Fenn. If Fenn helps you run and eat better, a short review helps other runners find it.

Small fixes and improvements.

### 1.6.0 — 2026-09-21

Fenn is now a subscription app: everything in the app is included, and it starts with a 3-day free trial. If you already bought Fenn Pro, tap Restore Purchases on the first screen — nothing changes for you.

Also in this update:
• Edit or delete your own recipes from any screen — including Recipes ▸ Library, where they used to be read-only
• Create one right there with New recipe, without going through Add food first
• Deleting a recipe no longer leaves you on a screen that never finishes loading
• The run summary in Profile opens your run history, and the streak badge opens Progress
• Long-press the round buttons at the top of Run to see what each one does

Fixed: on the Run screen the estimate card was cut off at the bottom and the START glow sat on top of it.

### 1.5.1 — 2026-09-16

No release notes.
