Train hard, tuned to recovery

Free · In‑App Purchases

Plan on your phone, push at the gym from your wrist. On-device AI reads HRV, sleep & resting HR to suggest today's load. Auto 1RM, 873 exercises. No ads, no tracking. ■ Plan on your phone, push on your wrist. A logger for serious lifters Oikomi — meaning "the final push" — is a strength-training logger built for intermediate-to-advanced lifters who want to focus on the quality of every set. Plan routines and review history on your phone at home; at the gym, record sets from your wrist alone. Recovery-aware coaching that reads your HRV and sleep, built entirely on Apple's own frameworks with privacy by design. Stack every hard-won rep, with confidence. ■ Highlights ◇ Log at the gym from your wrist — leave the phone behind Build routines ahead of time, then run and record whole sessions from your wrist. Enter reps and weight fast with the Digital Crown — one set in 1–3 taps. A Live Activity keeps set count, elapsed time, and your rest timer always visible. ◇ Read your HRV and sleep to judge today's push — free Oikomi reads HRV, resting heart rate, and sleep from Health to show today's condition and a clear "push or hold back" call (an HRV-based deload suggestion), free of charge and computed entirely on-device — no external LLM APIs. Deeper coaching — PR prediction, per-muscle volume warnings, and long-term trend analysis — is part of Pro. ◇ 873-exercise library Covers gym, bodyweight, dumbbell, barbell, cable, and machine movements. Search by muscle, equipment, or location, and add your own custom exercises. ◇ Automatic 1RM and estimated intensity Estimates 1RM from weight × reps (Epley / Brzycki) and visualizes per-exercise personal-best history and trends. ◇ Routine management Save your go-to push / pull / leg menus as routines. Start a session in one tap with last time's values pre-filled. ◇ Two-way Health integration Completed workouts are saved to Health as HKWorkout and reflected in your activity rings. Reading HRV, sleep, resting heart rate, and body weight — and today's condition — is free; long-term trend analysis is Pro. ◇ Widgets / Smart Stack Show this week's active days, active-week streak, and latest PR on the Lock Screen, Home Screen, and your watch's Smart Stack. ◇ App Intents / Siri input "Hey Siri, log 80 kg bench press for 10 reps in Oikomi" — from starting a session to recording, all by voice. ■ Serious about privacy No third-party analytics SDKs, ad libraries, or tracking — ever. Everything runs on-device, and nothing leaves your device without your consent. iCloud sync is a Pro opt-in feature, isolated automatically by your Apple ID. See our Privacy Policy for details. ■ Free features • Core logging, unlimited history, wrist-based recording, writing to Health • HealthKit reading (HRV / resting heart rate / sleep / body weight) • Today's condition + HRV-based deload / push suggestions • 5 routines, 5 custom exercises • Live Activity / Dynamic Island ■ Pro features • Advanced AI coaching (PR prediction / per-muscle volume warnings / plateau detection) • Long-term condition trends (HRV / sleep / resting heart rate / body composition) • Advanced analytics (per-muscle volume / per-exercise trends) • Unlimited routines (5 on Free) • Unlimited custom exercises (5 on Free) • iCloud sync across your devices • CSV data export • 14-day free trial to start • ¥780 / month or ¥4,500 / year (about ¥375 / month) • Payment is charged to your Apple ID at confirmation of purchase • Auto-renews unless turned off at least 24 hours before the period ends • Manage in iOS Settings → your name → Subscriptions • Terms: https://bukamasedo.github.io/oikomi/legal/terms/ • Privacy Policy: https://bukamasedo.github.io/oikomi/legal/privacy/ ■ Supported devices iPhone (iOS 26+) / Apple Watch (watchOS 26+) ■ Medical disclaimer This app provides health and fitness information, not medical advice.
