SyncFit reads the Apple Health data you choose and delivers it where you want it: iCloud Drive, Google Drive, any Files folder, your own REST API, a PostgreSQL or SQL Server database, email, or your Calendar. There is no SyncFit server in between. Every export runs on your iPhone and goes straight from your phone to the destination you picked. WHAT YOU CAN EXPORT Over 190 Apple Health types: heart rate, HRV, resting heart rate, oxygen saturation, steps, distance, active and basal energy, exercise and stand time, sleep stages, body measurements, workouts with routes and heart rate data, ECG, audiograms, state of mind, nutrition and more. Pick the metrics, the date range and the units. FORMATS CSV with one row per sample, ready for Numbers, Excel or Google Sheets. JSON in a documented schema with stable sample identifiers. A JSON layout compatible with Health Auto Export importers. GPX for workout routes. Raw samples or hourly, daily, weekly and monthly aggregates. DESTINATIONS • iCloud Drive and Files: CSV export is included free. • Google Drive • REST API: POST or PUT the file to your endpoint with a bearer token and custom headers. Retries with backoff on transient failures. • PostgreSQL and SQL Server: structured rows, tables created for you, upserts by sample id so re-running never duplicates. • Email: send the file as an attachment through your own SMTP account. • Calendar: put workouts and sleep sessions on a calendar you choose. AUTOMATIONS Run exports on a schedule, when new data arrives, or when a workout ends. Incremental jobs remember where they left off and only send new samples. History shows every run with its status. Reminders and completion alerts keep you informed. Shortcuts and Siri can trigger jobs and read your latest readings. TODAY DASHBOARD See your key metrics at a glance and customise which ones appear. Open any metric for historical charts. SYNCFIT FOR MAC The same purchase includes the Mac app. Send a dataset through your own iCloud and explore it with dashboards, period comparisons, notes and tags, and PDF and HTML reports. Read directly from iCloud, Google Drive or your PostgreSQL or SQL Server database. PRIVACY Your health data stays on your devices and goes only to destinations you configure. SyncFit has no cloud, no analytics on your health data, and no account requirement. Credentials are stored in the iOS Keychain. Sign in with Apple is optional and used only to share your purchase between devices. PRICING The Today dashboard, saved manual jobs and CSV export to iCloud Drive or Files are free.
