I used to weigh myself once a week on an old analog scale. It was inaccurate, didn’t track trends, and I’d forget to log it. My fitness progress was guesswork – weight up one day, down the next, no clue why. I tried cheap $19 digital scales – they drifted 5 lbs, no app sync. Then I bought the current #1 best-selling smart scale on Amazon that everyone said “tracks everything and syncs perfectly.” Nine months later I have a full body composition history, motivation from daily trends, and I’ve lost 18 lbs without guessing.
The Scale That Made Weight Loss Trackable: RENPHO Elis 1 Smart Body Fat Scale

Bought it after it held the #1 spot in Smart Scales for 32 straight months with 200,000+ reviews averaging 4.7 stars. It is now on my bathroom floor.
Real features that actually track progress:
- 13 body metrics: weight, BMI, body fat %, muscle mass, bone mass, water %, etc.
- Bluetooth sync to app (RENPHO Health) – iOS/Android
- Unlimited users + baby/pet mode
- High-precision sensors (0.2 lb accuracy)
- Tempered glass + ITO coating
- Works with Apple Health, Google Fit, Fitbit
My 9-month body-tracking log:
- Day 1: First weigh-in – baseline data.
- Week 2: Daily weigh-ins – saw water weight fluctuations, stayed consistent.
- Month 2: Dropped 8 lbs – app showed fat loss, muscle gain.
- Month 4: Vacation mode – tracked travel weight gain, back on track fast.
- Month 6: Baby mode – weighed my 6-month-old easily.
- Month 9 (now): Just hit 18 lbs lost. App shows progress charts. Still accurate.
Cons:
- Needs app for full data (but scale shows weight standalone)
- Works best barefoot
