You log every meal in MyFitnessPal. You track every run in Strava. But every morning you step on a basic bathroom scale — and your smart scale MyFitnessPal Strava sync is the missing link, write a number down somewhere — or worse, just forget it — and that data never makes it into the apps you actually use. The whole system has a hole in it, and a good smart scale is the patch.
The thing is, not every smart scale MyFitnessPal Strava combo works well. Some work beautifully with Apple Health but ignore MyFitnessPal. Others are built for Garmin’s ecosystem but lock you out of Strava. Before you spend money on one of these things, it pays to know which ones actually talk to the apps already running your fitness life.
| Scale | MyFitnessPal Sync | Strava Sync | Best For |
|---|---|---|---|
| RENPHO Bluetooth Body Fat Scale | Direct | Indirect (via Apple Health / Google Fit) | Best budget pick for MyFitnessPal users |
| Withings Body Smart | Direct | Direct | Best whole-ecosystem integration |
| Garmin Index S2 | Indirect (via Apple Health / Google Fit) | Direct (native Garmin Connect → Strava) | Best for Garmin & Strava athletes |
| eufy Smart Scale P2 Pro | Indirect (via Apple Health / Google Fit) | Indirect (via Apple Health / Google Fit) | Best feature-to-price ratio, 16 metrics incl. heart rate |
What to Look for in a Smart Scale MyFitnessPal Strava Setup
Before getting into specific smart scale MyFitnessPal Strava picks, a quick reality check: most smart scales sync to their own companion app first, and then push data to third-party apps via integrations. The chain usually goes: scale → brand app → Apple Health or Google Fit → MyFitnessPal or Strava. A few connect more directly. Understanding this saves a lot of frustration when you’re setting things up.
What actually matters for any smart scale MyFitnessPal Strava setup: Does it sync automatically (no manual entry)? Does it support the apps you use? How many body metrics does it track? Is setup painless? Those four questions will narrow the field pretty fast. If you also want wrist-based tracking, see our best fitness trackers under 100 dollars guide.
RENPHO Smart Scale — Best Budget Pick for MFP Users
The RENPHO Bluetooth Body Fat Scale is one of the most popular smart scales on Amazon for a reason: it’s cheap, it tracks 13 body composition metrics, and its app integrates directly with MyFitnessPal. Step on the scale, open the RENPHO app, and your weight and body fat percentage push straight into MFP’s diary. For most people, that’s the whole workflow right there.
Strava doesn’t have a native RENPHO integration, but the data flows through Apple Health or Google Fit, and Strava can pull from those. It’s one extra hop, but it works. At this price point, that’s more than acceptable.
RENPHO Bluetooth Body Fat Scale
The shortest path from stepping on a scale to a number inside MyFitnessPal.
- Direct MyFitnessPal sync
- 13 body composition metrics
- Supports up to 8 users
- Trade-off: No Wi-Fi, so your phone has to be nearby, and Strava sync goes the long way round.

Withings Body Smart — Best for Whole-Ecosystem Integration
The Withings Body Smart is the gold standard for app integration, full stop. As a smart scale MyFitnessPal Strava users love, it connects over Wi-Fi, which means it syncs automatically in the background — no phone required. Step on, walk away, and by the time you’ve made your coffee the data is already in your apps.
Withings has one of the broadest MyFitnessPal and Strava integration lists of any smart scale maker: Apple Health, Google Fit, MyFitnessPal, Strava, Fitbit, Garmin Connect, Runkeeper, Lose It!, and more. If you’re the kind of person who runs on Strava, logs food in MFP, and tracks HRV in Apple Health, this thing becomes the invisible backbone of your whole fitness data stack. It measures weight, body fat, water percentage, muscle mass, and bone mass. The app (Health Mate) is genuinely well-designed and doesn’t feel like an afterthought.
Withings Body Smart
You step on it and walk away — no phone in the room, no app to open.
- Wi-Fi sync with zero friction
- Weight, body fat, water, muscle and bone mass
- The broadest app integration list in this roundup
- Trade-off: Pricier than the budget options, and there’s no heart rate measurement.

Garmin Index S2 — Best for Garmin & Strava Athletes
If your training revolves around Garmin and Strava, this smart scale MyFitnessPal Strava setup is an obvious match, the Garmin Index S2 is an obvious choice. It syncs directly with Garmin Connect, and Garmin Connect pushes body composition data to Strava automatically as a body measurement activity. It’s a tight, native integration — no workarounds required.
The scale itself tracks weight, body fat, body water, bone mass, skeletal muscle mass, and BMI. It’s built to Garmin’s typical quality standards: solid, no-nonsense, accurate. The companion app is less flashy than Withings’ but highly functional. For MyFitnessPal, the data goes through Apple Health or Google Fit — not direct, but it works. Curious how Garmin stacks up against Apple Watch overall? Read our Garmin vs Apple Watch comparison.
Garmin Index S2
The one that lands in Garmin Connect natively, if that’s already where your training lives.
- Native Garmin Connect and Strava sync
- Wi-Fi enabled
- Colour display shows trend data
- Trade-off: Expensive for what it does, MFP sync is indirect, and it only pays off inside the Garmin ecosystem.

eufy Smart Scale P2 Pro — Best Feature-to-Price Ratio
The eufy Smart Scale P2 Pro punches above its price point. It tracks 16 measurements — including heart rate, which most smart scales skip entirely — and features both Bluetooth and Wi-Fi sync. The EufyLife app connects to Apple Health and Google Fit, which pipes data into MyFitnessPal. Strava isn’t a direct integration either, but flows through the same health platform bridge.
The real differentiator is the 3D virtual body model feature: the app generates a visual body shape estimate based on your measurements. It’s genuinely useful for tracking progress when the scale number isn’t budging but your body composition is shifting. If you’re strength training and watching muscle grow while fat shrinks, this is the scale that’ll show you what’s actually happening.
eufy Smart Scale P2 Pro
The most measurements per dollar here, heart rate included.
- 16 measurements including heart rate
- Wi-Fi and Bluetooth
- 3D body model visualisation
- Trade-off: MFP and Strava sync go through Apple Health or Google Fit, and the eufy app is basic.
Current price and availability shown on Amazon.
Quick Comparison: Which Scale Fits Your Setup?
- You live in MyFitnessPal → RENPHO (direct MFP sync, best budget option)
- You run on Strava and wear a Garmin → Garmin Index S2 (native Strava pipeline)
- You use multiple apps and want everything connected → Withings Body Smart (widest integration list)
- You want the most data for the money → eufy P2 Pro (16 metrics, heart rate, great price)
A Note on App Sync Chains
Most scales that “sync with Strava” or “sync with MyFitnessPal” do it via Apple Health or Google Fit as the middleman. That’s fine — it works reliably once set up — but it’s worth knowing so you’re not surprised when there’s no direct scale-to-app connection. The only truly direct MFP integrations in this list are RENPHO and Withings. For Strava, only Garmin and Withings have first-class integrations. Everyone else goes through the health platform bridge.
Set it up once, test the data flow, and then forget about it. That’s the whole point.
The Bottom Line
If you’re already logging workouts and meals in apps, a smart scale MyFitnessPal Strava setup makes the habit completely frictionless. The data just appears where you need it, automatically, every morning. No manual entry. No forgotten weigh-ins. Just a cleaner picture of what’s happening over time. To round out your tracking stack, see our picks for the best recovery wearables for strength training.
Pick the smart scale MyFitnessPal Strava option that fits where you already live: RENPHO for MFP users on a budget, Garmin Index S2 for Strava athletes deep in the Garmin world, Withings Body Smart if you want universal compatibility, or eufy P2 Pro if you want the most features per dollar. Any of them will close the gap in your data stack.
How Accurate Are Smart Scales, Really?
Fair question, because the body-fat number causes the most confusion. Smart scales estimate composition through bioelectrical impedance — a tiny current whose resistance varies with muscle, fat, and water. The absolute number can be off by several percent and swings with hydration, which is why stepping on after a salty dinner tells a different story than a fasted morning.
The fix isn’t a better scale — it’s better habits: weigh at the same time daily (fasted mornings win), and watch the two-week trend line instead of any single reading. Weight itself is measured accurately on all the picks above; treat body-fat percentage as a consistent-but-approximate trend, and the data becomes genuinely useful in MyFitnessPal and Strava instead of an anxiety generator.
Pick the scale that syncs where you already track, weigh at the same time every morning, and let the trend line do the talking. That’s the entire system — boring, automatic, and effective.
Frequently Asked Questions
Which smart scale has a direct MyFitnessPal sync?
RENPHO and Withings Body Smart are the only two in this roundup with a truly direct MyFitnessPal integration. The others route through Apple Health or Google Fit first, which still works but adds an extra hop.
Which smart scale syncs directly with Strava?
Only Garmin and Withings have first-class Strava integrations. The Garmin Index S2 pushes body composition to Garmin Connect, which then forwards it to Strava automatically as a body measurement activity.
Why doesn’t my smart scale’s body fat number match what I expect?
Smart scales estimate body composition using bioelectrical impedance, which swings with hydration — a reading after a salty dinner will look different from a fasted morning. Weight itself is accurate; treat body fat percentage as a trend to watch over two weeks, not a single precise number.
Do I need Apple Health or Google Fit to use these scales with MyFitnessPal?
For most of them, yes. RENPHO, Garmin, and eufy all route their MyFitnessPal or Strava data through Apple Health or Google Fit as a middleman. Withings is the exception, with direct integrations to both apps.
What’s the best smart scale for someone using Strava and a Garmin watch?
The Garmin Index S2. It syncs natively with Garmin Connect, which is already the hub feeding your Strava activities, so body composition data flows in without any workarounds.
