BodyPhase vs Koar

BodyPhase is a 120-day body recomposition program that lives entirely on your phone. No subscriptions. No cloud account. No third-party analytics. Every calculation runs on-device. WHAT IT DOES: HABITS A time-unlocked daily checklist follows your exact schedule — from 6:30 AM wake-up to 11 PM sleep. Each habit unlocks only when it's time, keeping you present instead of planning ahead. The week grid shows your completion rate at a glance. PROGRESSIVE WORKOUTS Four lifting sessions per week (Upper A / Lower A / Upper B / Lower B) plus daily mobility and recovery work. Every set tracks the weight you used last time, so the app always knows when to nudge you to go heavier. A 120-day scrollable strip lets you preview upcoming sessions or review past ones. PERSONALISED DIET Your daily calorie and macro targets are calculated from your actual stats — height, weight, age, sex — using the Mifflin-St Jeor BMR formula and ACSM activity multipliers. The intensity of your plan (Aggressive Cut → Bulk) is derived automatically from the gap between your estimated and target body fat percentage. Meals are split across five windows: Pre-Workout, Breakfast, Lunch, Snack, and Dinner. Every meal card shows exact gram amounts for your protein source (chicken, fish, or eggs) and carbs (oats or Sona Masoori rice), including the cooked-from-fridge equivalent so you never have to guess. WEIGHT PROGRESS Log your weight on any day and watch the trend chart build over time. Your BMI, estimated body fat, lean mass, and weeks-to-goal are all derived from what you log — no wearable required. PRIVACY BodyPhase collects zero data. Nothing leaves your device. All entries are stored in iOS local storage (UserDefaults). Optional iCloud Key-Value sync keeps your data in sync across your own devices — the developer has no access to it. There are no analytics SDKs, no crash reporters, no ad networks, and no external network requests of any kind. DESIGNED FOR People who want a structured, science-backed program without a monthly fee or a login screen. Everything is calculated for you — just follow the plan.

KOAR is a strength coach that adapts to your body, not just your preferences. It reads your recovery and fatigue, detects stalls before you do, adjusts volume and intensity to how you're actually recovering, and for women, tunes intensity to your cycle phase. This isn't a workout logger. It's a training system. Free to start. Works on iPhone alone, better with Apple Watch and AirPods. Full gym to just bodyweight, KOAR builds around what you have. HANDS-FREE COACHING Put your AirPods in, put your phone down, lift. A warm studio-quality coach (Kira or Wes) narrates every set: exercise intros, rest countdowns, brace cues before heavy lifts, form reminders, a halfway checkpoint. Works offline, no setup. INTELLIGENT PROGRESSION Every set feeds a progression engine built on exercise science. KOAR estimates your 1RM with an Epley-Brzycki ensemble, detects stalls before you notice, and auto-adjusts volume and intensity. It adds weight when you're ready and calls a deload when you need one, using severity-weighted analysis of your last 4 sessions instead of waiting for you to fail twice. ADAPTS TO YOUR BODY A 5-second wellness check-in (energy, sleep, mood) calibrates every workout. KOAR reads HRV and nutrition from Apple Health to adjust volume and recovery, and uses menstrual cycle data to tune intensity by phase. APPLE WATCH COMPANION Live heart rate with zone coloring, rest timers based on heart-rate recovery (not just the clock), and rep detection tuned per exercise. If your Watch drops mid-workout, your iPhone is the source of truth, no data lost. TEMPO COACHING KOAR prescribes lifting tempo (eccentric, pause, concentric, pause) and guides each phase with haptic pulses on your wrist. COACHING INSIGHTS A Coach tab surfaces patterns you'd miss on your own: masked fatigue, volume response profiles, and wellness-performance correlations unique to you. PERIODIZATION THAT RUNS ITSELF Mesocycles with automatic phase progression, volume landmark tracking per muscle group (MEV/MAV/MRV), and goal-aware deloads. Hypertrophy deloads cut volume with lighter weights; strength deloads cut volume but keep full working weight for CNS readiness. BUILT FOR EVERY LEVEL Beginners get guided weight discovery with live cues. Intermediate lifters get periodized mesocycles with automatic deloads. Advanced lifters get RPE/RIR autoregulation and sex-based programming. EARN YOUR PROGRESS XP tied to training quality, not just showing up. 20 rank tiers, 18 badges for real milestones like 12-week streaks and pressing your body weight, and streak flames that evolve from Bronze to Obsidian over a year. AI PROGRAM BUILDER Describe your ideal training in plain English and KOAR builds a complete periodized weekly plan that respects evidence-based volume landmarks. STRAVA SYNC Completed workouts post to your Strava feed automatically as Weight Training activities. WIDGETS & LIVE ACTIVITIES Today's workout, weekly volume by muscle group, and your streak flame on the Home and Lock Screen. Live Activities keep your current set on Dynamic Island.
