Get your smart scale's weigh-ins into Garmin Connect, straight from your iPhone. Two ways in, one tap out. APPLE HEALTH ROUTE: ANY SCALE If your scale's app saves weight to the Health app, Scale Relay picks it up and sends it to Garmin Connect. Works with Withings, Renpho, Eufy, Etekcity, Zepp Life, Wyze, Picooc and any other app that writes weight to Apple Health. Body fat and BMI come along when your scale's app provides them. BLUETOOTH ROUTE: XIAOMI SCALES, NO OTHER APP NEEDED Step on a Mi Body Composition Scale 2 or a Xiaomi Body Composition Scale S400 and Scale Relay reads the measurement directly: weight, body fat, muscle mass, bone mass, water, BMI and BMR. The S400 needs a one-time authorization with your Xiaomi account. WHAT YOU GET โข A preview of every weigh-in before it is sent; nothing leaves without your tap โข Body composition in Garmin Connect, not just the weight โข Weigh-ins from the last 7 days are included; Garmin Sync unlocks older history โข One Garmin sign-in, two-factor authentication supported โข A "Sent to Garmin" list so you know what arrived FREE TO TRY Your first two syncs are free on either route. Unlimited syncing is a single one-time purchase called Garmin Sync. No subscription. PRIVACY FIRST Your measurements stay on your iPhone and go only to your own Garmin account. No Scale Relay account, no tracking, no ads. REQUIREMENTS โข iOS 17 or later โข A Garmin Connect account โข Apple Health route: any scale app that writes weight to the Health app โข Bluetooth route: Mi Body Composition Scale 2 or Xiaomi Body Composition Scale S400 Scale Relay is an independent app. It is not affiliated with, endorsed by or associated with Garmin, Xiaomi, Withings, Renpho, Eufy, Etekcity, Zepp, Wyze, Picooc or any other scale or fitness-platform maker.

FitContext turns the data your Apple Watch, sports watch and health apps already collect into clear training insights - on your device, under your control. TRAINING ANALYSIS - Heart-rate zones: a personal 5-zone model with per-workout time in zone, computed from your heart rate data - Training load: acute:chronic workload ratio (ACWR), CTL/ATL/TSB fitness-fatigue balance, monotony and strain, computed from your exercise sessions, distance, speed, power and calories - Recovery: a daily overview of resting heart rate, heart-rate variability (HRV), sleep and VO2 max trends to judge training readiness ALL YOUR SOURCES, ONE PICTURE FitContext reads your data from Apple Health, so it works with Apple Watch, Garmin, Oura, Polar, Whoop, Fitbit and any other device or app that syncs to Apple Health. You can also connect intervals.icu with your own API key to pull in workouts and wellness data from Garmin, Polar, Suunto, COROS, Wahoo and more. When several sources write the same data, you choose which one wins per category. YOUR DATA, YOUR COACH Generate a structured training report and share it with whoever you trust - your coach, or the AI assistant of your choice (ChatGPT, Claude, Gemini). FitContext has no built-in AI service, no account and no developer server: your health data stays on your device and leaves it only when you explicitly share a report. FOOD DIARY WITH AI ESTIMATES Log meals the way that suits you: snap a photo, add a note, search the built-in food database, scan a product barcode or photograph a nutrition label (read on your device). Want calories and macros estimated by AI? Share meals to the AI chat you already use and paste its reply back, or plug in your own OpenRouter API key for direct analysis - or skip AI entirely and log manually. You review every estimate before it lands in your diary. ALSO INCLUDED - Training goals with countdown - Blood-pressure logging - Built-in demo data, so you can explore every feature before connecting Apple Health - Full English and Polish localization FitContext is not a medical device and does not diagnose, treat, cure or prevent any medical condition. For medical advice, consult a healthcare professional.

Verdict
The clearest difference is price: Scale Relay at Free against Fitcontext's $0.99. Fitcontext's advantage is in-app purchases (none vs 1). On update cadence, ads, device support and iOS requirement there is nothing between them.
