health4ai vs Footfall

health4ai moves the health data on your iPhone into a Google Sheet or a database you own, so you and any AI assistant can work with it. The Health app holds years of your sleep, HRV, heart rate, workouts and 150+ other metrics, but nothing outside your iPhone can read it. health4ai is the bridge. TWO WAYS TO SAVE Google Sheets: sign in with Google and health4ai writes one row per day (steps, sleep, heart rate, HRV, workouts and more) into a spreadsheet in your own Google Drive. No setup beyond signing in. health4ai can only see the files it creates. Your own database: sync every HealthKit sample into a Postgres database you control, typically a free Supabase project, and any MCP-compatible AI client can then query it in plain language. A setup checklist in the app shows which steps are done, and setup takes about ten minutes. There is no health4ai account and no health4ai server either way. NOT JUST APPLE WATCH health4ai syncs anything that writes to the Health app. That includes rings, watches, scales, blood pressure cuffs, glucose monitors and workout and nutrition apps, for example Oura, Garmin, Polar, Coros, Withings, Omron, Dexcom, Strava, Peloton, MyFitnessPal and Cronometer. Coverage depends on what each brand shares with the Health app. The Your Sources screen shows every device and app that has sent data. WHAT IT DOES Syncs sleep stages, HRV, resting and walking heart rate, steps, distance, workouts, active energy, VO2 max, respiratory rate, body mass and more. Syncs each time you open the app, and in the background as often as iOS allows. Sync History shows every run, so you never have to wonder. Backfills your history too, not just today. Tells you plainly when a metric is not being shared with the app, instead of showing you an empty chart and calling it complete. YOUR DATA STAYS YOURS health4ai never receives, stores or transmits your health data. It travels from your iPhone to your spreadsheet or your database and nowhere else. No analytics on your health data, no advertising, no third-party sharing, no resale. The iOS app and the companion MCP server are both open source under the MIT license, so you can read exactly what they do. WORKS WITH ANY AI Any AI client that speaks the Model Context Protocol, through the companion open-source MCP server (pip install health4ai). The app's Connect Your AI screen gives you copy-paste setup for Claude Desktop, Claude Code and Cursor. Purpose-built tools cover daily snapshots, trends, baselines, sleep, workouts and search across your records. FREE No subscription, no in-app purchases, no account, no upsell.

Footfall shows the steps your iPhone already counted, and almost nothing else. It has no step counting algorithm of its own, and that is the point. It reads the daily totals from Health, the one place on iOS where an iPhone and an Apple Watch are added up without the same walk being counted twice. The number here is the number there. No second opinion, no arguing with your watch about this morning. The rest of the app puts that number in front of you. A widget on the Home Screen. A circle or a rectangle on the Lock Screen. A medium widget for the week. They refresh through the day, and say so rather than pass off yesterday's total as today's. ON YOUR WRIST Ten years after the first Apple Watch, no built-in complication shows a step count as a number. Footfall does, in four shapes, on any face with room for one. The watch reads Health on the watch, so the count is right even when the iPhone stayed at home, and there is nothing to fall out of sync. The complications are free, like every other widget here. ONE SCREEN, TOP TO BOTTOM A ring that warms from clay to amber and turns gold at your goal, with the count rolling in the middle. The shape of the day: twenty four hourly bars that show when you walked, not only how much. The week in seven bars you can tap, and tapping one moves the top of the screen to that day. The month as dots, each one sized by its steps, and a swipe back through the months before it. Then four numbers: your seven day average, your thirty day average, your best day, and the days you met your goal. NOTHING YOU DID NOT ASK FOR No account. No ads. No analytics. No notifications, no badges, no levels. The streak stays off until you turn it on, because a streak nobody asked for turns into a debt. The app opens no network connection at all, so nothing can leave the phone. Nothing is written back into Health either. FOOTFALL PLUS Counting, the widgets, the watch complications, the goal, kilometers or miles, the day, the week and the month are free and stay free. Footfall Plus is one payment, once, and it adds every past month one by one, the full year day by day, your rhythm by day of the week, records and totals from the first day Health holds, and a CSV export. No subscription. Nothing renews. WHAT IT NEEDS Permission to read steps and walking distance from Health, and nothing else. iOS has been recording those since you got the phone, so your history is usually there the first time you open the app. If you have never walked with the iPhone on you, Footfall will show you an honest empty day. Available in 45 languages. iPhone, iOS 18 and later. Apple Watch, watchOS 11 and later.
