ChironMotion Load helps you keep a private training log and review training load, wellness, and recovery trends in one place. Log workouts, RPE, duration, wellness status, body weight, and sport types. When you choose to allow HealthKit read access, the app can add personal context such as steps, active energy, exercise minutes, sleep, resting heart rate, HRV, and respiratory rate. HealthKit authorization is optional, and you can still use manual training logs, wellness records, reports, widgets, and local reminders without it. Pro features unlock deeper trend views, weekly and monthly reports, PDF export, CSV export workflows, and training review tools. StoreKit purchases and restore purchases are handled through Apple. HealthKit-derived trend data stays on the device. Non-HealthKit app data, such as training logs, profile settings, sport types, weight entries, and reports, is stored locally in this build. The app can create user-initiated iCloud Drive CSV backups for non-HealthKit data, and those backups exclude HealthKit-derived trend data. ChironMotion Load is for personal training review and planning only. It does not provide medical diagnosis, treatment, disease prevention, emergency alerts, or real-time monitoring.

What kind of turtle is your posture? One side photo answers in sixty seconds. THE SIXTY-SECOND TECH NECK TEST No sign-up. You get a posture score and the turtle your posture makes: Phone Navigator, Monitor Explorer, Perfect Balance Master. Keep it as a card and send it to a friend. Spend the day in front of a screen and your neck is the first thing to drift forward. Shellog wakes it up in seven minutes a day. Scute is the turtle your posture makes: every class you finish straightens him a little and lands a plate on his shell. TWO THINGS A DAY A ten-second body check and one short class. Fill both and the day is done; your first activity of the day adds a plate. Seven plates make a week, three fill it, and every day you show up your streak grows. CLASSES COME IN SERIES Tech Neck Reset with Scute and Open Up Rounded Shoulders with Somi, five classes each, seven minutes per class. A pelvis series with Pelvy is on the way. Shellog picks your next class for you. ONCE A WEEK, A POSTURE CHECK-IN Two photos, front and side, in about a minute. You get a score with a one-word read, the change since last time, and a ring for each area: neck, shoulders and pelvis. Scute takes on your posture, and your next series is chosen from it. A POND WITH FRIENDS Your friends' turtles live on your home screen, and a small star shows who showed up today. You see how each other stand, and a tap sends one nudge. A weekly pond ranking counts plates, not scores, and first place wins one thing: a golden lily pad next week. A BODY-CHECK TIMELAPSE One selfie a day from the same angle, and a month becomes a single card. Your selfies stay on your phone. A REMINDER, ONLY IF YOU WANT ONE After your first class of the day, one tap sets a daily reminder. If you used BodyBalancer: posture check-ins continue, and your past measurements stay at bodybalancer.app. Shellog is not a medical device and does not diagnose, treat, cure, or prevent any medical condition.
