I wore my Apple Watch for years without really using what it was telling me. The data was there - precise, reliable - but never explained, never put into context. As a coach and athlete, I knew this data had value, but it wasn’t actionable. So instead of switching to another watch, I built Morphy. To understand my recovery, manage my training, and perform at my best. KEY FEATURES BodyLevel – your daily condition in a single score combining sleep, heart data, training, and activity Body Battery – your real energy level, based on heart recovery and variability Training Load Management – compare your current load to your usual level and balance stress vs fitness Effort Zones Breakdown – are you training at the right intensity? Estimated VO2 Max Speed (VMA) – calculated from your workouts Target Paces – know how fast to run to improve based on your current level Race Predictions – estimated finish times for official races Sleep Debt – how much you’ve actually recovered this week And more… CONFIDENTIALITY All your data stays on your device. No account. No cloud. No external AI. Morphy reads your Apple Health data locally - it never leaves your iPhone. LEGAL Morphy uses Apple Health (HealthKit) data. This app is not a medical device and does not replace professional medical advice.
