Arc: Health & Fitness Tracker
Train & Track With Your Crew
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
Now with GPS workout tracking, Live Activity during runs, and Spotify-powered crew sessions. Track every rep, mile, and meal alongside your crew.
Track every rep, meal, and mile in one beautifully simple app — then train alongside your crew in real time.
FOOD & NUTRITION
Snap a photo of any meal and AI instantly estimates your calories, macros, and caffeine. Or type what you ate for the same one-tap analysis. Arc tracks your daily goals and sends smart meal-time reminders so nothing gets missed.
WORKOUT TRACKING
Log strength sessions set by set, or head outside and track any run, walk, ride, or hike with built-in GPS — route, pace, distance, and duration saved automatically. A Live Activity on your lock screen shows real-time stats mid-session. Build multi-week training blocks with a rotating schedule that auto-fills each day. Track PRs, lift maxes, volume streaks, and weekly cardio records. One tap shares an entire training plan with your crew.
GYM BOARD
Pull up the Gym Board on any TV or browser and watch your crew's session come alive. Member cards update in real time with every set logged, rest timers, recovery scores, and PR announcements. A live chat feed floats messages up the screen like a live stream. Connect Spotify and let everyone queue songs from their phone — with skip voting so the crew controls the vibe. No login required. Works on any browser.
DAILY READINESS BRIEF
Every morning, Arc generates a personalized AI readiness brief — reading your HRV, sleep, training load, nutrition, and mood to give you a plain-English summary of how your body is doing today, with a 1–10 readiness score and a specific recommendation.
APPLE HEALTH INTEGRATION
Reads steps, active calories, heart rate, HRV, resting heart rate, sleep stages, and workouts. Optionally writes food, water, weight, workouts, and sleep back to Apple Health so your data stays in sync.
SLEEP & RECOVERY
Log sleep manually or pull real data from your Apple Watch, Oura Ring, or any sleep tracker that syncs to Apple Health — with Deep, REM, and Core stage breakdowns. Recovery Trends charts your HRV and resting heart rate over weeks. Correlation cards reveal how alcohol and workouts move your recovery numbers.
HEALTH DASHBOARD
A fully configurable home screen with tap-to-log widgets for water, sleep, weight, mood, alcohol, caffeine, creatine, biohacks, and mindfulness. Add what matters. Remove what doesn't.
CREW & SOCIAL
Create or join a crew, invite friends, and see each other's workout summaries and streaks on the group feed. Compete on the weekly leaderboard, share training plans with one link, and start a live gym session where the whole crew logs together in real time.
STREAKS & MILESTONES
Workout streaks track three-workout weeks. Alcohol-free streaks work the same way. Credit the weeks you've already put in and pick up right where you are.
PROGRESS & ANALYTICS
Weight trend, 7-day nutrition breakdown, mood and workout chart, sleep history with stage data, recovery trends, and lifestyle correlation charts — all from your own private data.
PRIVACY FIRST
All health data is stored locally on your device. Cloud sync is optional. No ads. No subscriptions. No selling your data. Ever.
What's New in 1.3.1
• This Week's Cardio — A new dashboard card tracks your weekly mileage and active time, with all-time personal records for distance and time so you can see when you're having your best week.
• Live Activity — Start a workout and your lock screen shows real-time stats so you never have to unlock your phone mid-session.
• Gym Board from Train tab — Start a group gym session directly from the Train tab without going through group settings.
• GPS sessions show distance — Runs, walks, and rides now display exact duration and distance in the Train tab.
• Bug fixes and improvements — Fixed an issue where sleep data from HealthKit was not appearing on the dashboard. Reaction picker in crew chat now works reliably. Resolved a photo picker issue on iOS with limited photo access.
