StepFill is the fastest, cleanest way to add the steps you walked — but didn't capture — to Apple Health. Walked on a treadmill, did cardio at the gym, took the dog out, or left your phone on the desk? Those steps really happened, but they never made it into Health. StepFill puts them back in seconds — no digging through Health's slow, one-at-a-time manual entry. HOW IT WORKS 1. Choose your activity — walking or running 2. Set when you did it — the start and end time 3. StepFill estimates the steps and saves them to Apple Health The estimate follows a realistic pace that varies minute to minute, so a 30-minute treadmill walk lands in Health as natural, uneven step data. Your steps are saved as regular step data, kept in Health on your device. SEE YOUR PROGRESS • A contribution heatmap shows your activity at a glance, color-coded around a 10,000-step daily goal • Tap any day for an hour-by-hour bar chart and the full list of entries • Edit or delete the entries you added, anytime • Viewing your history is always free PRIVATE BY DESIGN • Works entirely on your device — StepFill makes no network connections at all • No accounts, no sign-in, no tracking, no ads • No analytics and no third-party SDKs • Your step data is read only on your device — to show your history and let you edit your own entries — and never leaves your device STEPFILL PREMIUM Adding, editing, and deleting steps is part of StepFill Premium. Every new install starts with a 3-day free trial with full access — no purchase required. After the trial, unlock unlimited writing with a monthly or yearly subscription, or a one-time lifetime purchase. Viewing your history stays free, always. Restore previous purchases anytime. GOOD TO KNOW StepFill writes to Apple Health, so it needs a device that supports HealthKit and your permission to add steps. You can review or remove anything StepFill saved at any time in the Health app under Steps. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period. Manage or cancel in your App Store account settings.
