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.

About

Lunia

Features
Read full description

Lunia is a workout log made for women. Log gym sessions, runs, walks, yoga and classes in seconds, record runs with GPS, and see how your training sits next to your cycle, sleep and energy. Free, with no limits on logging. Some weeks the bar flies up. Some weeks the same weight feels welded to the floor. Lunia quietly tags every session with the phase of your cycle it happened in. After a few cycles you stop guessing. WHY LUNIA IS DIFFERENT Most cycle apps tell you what a generic hormone theory says you should do. Lunia shows you what your body actually did. "Your squat has averaged 6% heavier in your follicular phase, across 4 cycles." That is your data. It may not match anyone else's, and when there is no clear pattern yet, Lunia tells you honestly and shows how much more logging it would take to know. FREE, FOREVER • Unlimited logging for ten activities: strength, running, walking, HIIT, cycling, swimming, rowing, yoga, pilates and classes • GPS tracking for runs, walks and rides, then relive the route in 3D • Every session labelled with its cycle phase, in Library, Schedule and History • Runs, rides, swims, rows and walks imported automatically from Apple Health and Apple Watch • Rest timer and personal records • Cycle tracking: calendar, flow, symptoms and notes • A daily log for mood, energy, water, protein, sleep, weight, fasting and supplements • Home and Lock Screen widgets, Live Activities and Siri shortcuts • Stickers and cards to share your sessions • Your last 90 days of history, with basic charts • Share your cycle with a partner, end-to-end encrypted LUNIA PRO (optional) • AI Coach: ask about your own training, sleep and cycle, and get a written review of each workout with one thing to try next time. Runs on your iPhone with Apple Intelligence. • Training plans built for you from 700+ exercises (the first week is free) • Your cycle patterns: strength, volume and energy broken down by phase, with confidence intervals • Your monthly cycle recap, compared against the same days of your last cycle • Your full history, all-time, instead of the last 90 days • Advanced metrics: estimated 1RM trends, split analysis, and how your mood, energy, sleep, water, protein, weight and fasts move by phase • The full library of 180+ sessions, and unlimited saved sessions • CSV and PDF export of everything you logged Choose Annual (with a free trial) or Monthly and cancel anytime, or pay once for Lifetime with no subscription. HONEST BY DESIGN Lunia makes no hormonal or medical claims. When your data does not show a clear pattern, it says so. Your data stays on your iPhone. The AI Coach runs on the device, and cloud backup is free and optional: your history is encrypted on your phone before it ever leaves it, and is never sold or shared. Lunia is not a medical app and does not diagnose or treat any condition. For medical advice, talk to a professional.
