■ 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.
