• Weekly zone 2 and zone 5 minutes from your Apple Watch heart rate
EAT FOR YOUR GOAL
• 15,000+ foods offline, plus online USDA and Open Food Facts search

• Calories, protein, carbs, fat, fibre, sugar, salt — and potassium, magnesium, calcium, iron, zinc and vitamin D
• Adaptive calorie target that learns from your weight trend
• Your week as one calorie budget: a big day is evened out gently, and you can plan a big meal ahead and save up for it
• Calorie, level and quick-log widgets for the Home Screen and Lock Screen
• An app icon that shows your rank and changes with every new title
• Rewards as you level: accent colours, ring frames, a share card, a Classic look and Dark mode
RUNS FROM APPLE HEALTH
• Runs, rides, hikes and walks come in automatically with their route map, heart-rate zones and XP
YOUR JOURNEY
• A mountain you climb with XP: every workout, logged day and check-in moves you up, and each summit is a new title
• Your body goal sits beside it, measured on your smoothed trend, with milestones and a pace estimate. One heavy morning never sets you back
• Training for a 10 km, half, marathon or Hyrox? See the calendar against your readiness
WORKS WITH DayCurve (optional)

APPLE WATCH
• Train from your wrist, or let your Watch record heart rate while you log on iPhone
• Outdoor runs, walks and rides record their GPS route
GainCurve PRO (optional)
• Progress photos pinned to your level on the map, with a ghost of your last photo to line up, compare any two days, and a timelapse video of your progress — stored only on your iPhone
• Run analytics: pace-coloured routes, kilometre splits and best efforts
• Strength analytics: estimated one-rep-max trends for every lift, weekly hard sets per muscle and whether each muscle is building, maintaining or overreaching
• Sleep readiness, with our DayCurve app installed: how last night's sleep reads for today's training

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Redesigned Today tab: your path, this week and today's goals in one card, with food search and barcode scan up top.
• Quick add per meal: adjust the amount before adding. "Same as yesterday" lets you review and edit each item first.
• New Potions: streak shields save your streak on a missed day, Double XP potions for 1, 3 or 5 days.
• More quick workouts: every plan day plus new dumbbell workouts (upper, lower, push, pull, arms, conditioning), with filters. They don't change your plan.
• Apple Watch: log sets for workouts started on your iPhone, with the full workout on your wrist. The rest timer shows right after each set and pings and vibrates when it's up.
• Rest timer on iPhone with −15 s, +30 s and Skip.
