Excellent Weight Scale that keeps you on track.
This smart scale is a game-changer for anyone serious about their health and fitness goals. It’s so much more than just a weight scale!Right out of the box, the setup was a breeze. I downloaded the Starfit app, paired it via Bluetooth in just a minute, and was ready to go. The scale itself feels incredibly sturdy and well-made, not flimsy at all. The retractable handle is a fantastic feature, making it easy to get a full-body analysis.The real magic happens when you get your results. It gives you an incredible amount of detail—28 different body composition metrics including body fat, muscle mass, and even bone density. The bright, colorful screen on the handle shows you the most important stats immediately, which is a great touch. The app, however, is where the data really shines. It presents everything in clear, easy-to-read graphs and reports, letting you track your progress over days, weeks, and months. It even syncs seamlessly with Apple Health and Fitbit.This scale has completely changed how I think about my fitness journey. Instead of just focusing on the number on the scale, I can see if I’m gaining muscle while losing fat, which is much more motivating. It feels like having a professional body composition analysis at home. I can’t recommend this enough!

Informative and Easy to Use
I Received my scale and right out of the box, it was fully charged, and setup with the Starfit app was quick and painless. Entering my info and goals only took a minute, and the app synced with the scale immediately.The scale itself feels very solid and well-made, no cheap or loose parts. Using it is simple: step on with bare feet (covering the metal pads) and hold the handle with your thumbs and fingers on the sensors. Once it zeroes out, the measurement process takes maybe 15 seconds. The screen shows the progress, and then the app delivers a full report with more data than I expected.What impressed me most is the detail of the results. It doesn’t just show weight and body fat, it breaks things down in a way that reminds me of a lab report, with ranges, charts, and even graphs to track progress over time. You can print the report or keep everything stored in the app for easy reference.I bought this because I wanted more than just a number on the scale. I wanted to know if I was losing fat while keeping muscle. After just one day, I can already see this will be a valuable tool to track those changes. I’m excited to check my progress in 30 and 60 days.So far, I’m really impressed. This feels like one of the best purchases I’ve made for my fitness journey.

Outstanding Smart Scale
The design is sleek as it claims. Setup was simple. Make sure to read through the manual to understand the features (like with any new device), downloaded the app and filled the required info (correct height, age, and gender are a must for accuracy), connected my phone to the scale via Bluetooth and WiFi (the WiFi option is a great bonus), stepped on the scale, and within seconds, a detailed breakdown of my health data appeared on my phone. It all took only a few minutes. One of my favorite features is the large surface. It makes it super easy to stand on and the large color display makes it much easier to read my results. My other favorite features is the segmental body analysis. It’s been incredibly helpful in tracking changes over time and focusing on specific areas of my body that need work.It’s sturdy, accurate, and FSA/HSA eligible, which is a big plus. I like how it points out exactly which metrics of my body need the most attention. The data is pretty easy to read. It’s been huge in motivating m for health management. Directions and App are Very straight forward, easy to use, and extremely insightful. I’ve had this scale for a while and tested its functionality over time and it hasn’t disappointed. For best results, making periodic comparisons, and monitoring progress, I’ve found that weekly to biweekly weigh-ins work best. It gives you a clearer picture of trends without getting caught up in daily fluctuations. Overall, this scale is amazing value for money. Just remember, it is a smart device, so treat it like smart tech. Learn it, use the app, and you’ll absolutely love it! Highly, Highly Recommend!!

Smart way to see your progress in full color
I’ve used plenty of bathroom scales before, but this one feels like it belongs in a fitness studio rather than my home. The big standout for me is the retractable handle with its bright, full-color screen. I don’t have to pull out my phone every time just to see results. It shows my weight plus six other key stats immediately, and even points out how they’ve changed since my last check. That instant feedback is surprisingly motivating.What really impressed me is how detailed the measurements are. Instead of just giving me weight and body fat, it breaks down 28 different metrics using both hand and foot sensors. It tracks things like muscle mass and torso composition, which makes it easier to understand where progress is actually happening. For someone trying to build strength and not just lose pounds, that extra detail matters.The app is another strong point. It stores everything automatically and lets me look back over days, weeks, or months to spot trends. I like being able to generate reports, especially since I share them with my trainer. Syncing with Apple Health and other fitness apps makes it even more convenient since all my health data stays in one place.On top of all that, it’s perfect for families or groups. The surface is sturdy and large enough for different foot sizes, and multiple profiles can be created under one account. We’ve been using it as a household, and it’s nice that everyone gets their own tracked data without confusion. If you want a scale that gives a deeper picture of health and doesn’t just stop at weight, this one delivers.

Works right out of the box. Easy to set up and use for multiple people. Information is clear and seems quite accurate.

Ein sehr schönes Gerät. Sehr viele Werte um auswerten, eine übersichtlich App. Alles in allem ein gutes Paket.Zu der Genauigkeit kann ich nicht zu allen Werten etwas sagen aber Gewicht, Körperfett, Skelettmuskelmasse und Körperwasser sind die Werte plausibel.Der Preis ist in meinen Augen okay im Verhältnis zur Leistung was das Gerät kann.

Fazit vorweg: die Waage kann mit den professionellen Geräten im Fitnessstudio mithalten.Kaufgrund: unsere bisherige Waage hat nur 4 Messpunkte und ohne Handsensoren werden bestimmte Messwerte nur hochgerechnet und sie nicht genau.Die Waage sieht schick aus und ist schnell im Einsatz. Zur Nutzung benötigt man die App Starfit, nach kurzer Registrierung verbindet man die Waage per Bluetooth und schon geht’s los.Wichtig bei der Nutzung: die Handsensoren müssen auf Bauchnabelhöhe im 45 Grad Winkel gehalten werden, ansonsten schlägt die Messung fehl, wird allerdings in der App auch angezeigt. Nach zwei bis drei Versuchen klappt das dann auch.Die Ergebnisse passen 1:1 Zundern Werten aus meinem Fitty, so dass ich davon ausgehen kann, das sie sehr präzise Ergebnisse liefert.Die Auswertungen können in einem Diagramm mit den vorangegangenen Daten verglichen werden, praktisch um sehen zu können wo alles passt und wo man mehr Gas geben muss. Wir nutzen die Waage zu zweit mit zwei verschiedenen Profilen, es können aber auch noch mehr angelegt werden.Großes Plus in puncto Umwelt: der Hersteller hat mitgedacht und verzichtet auf ständigen Batteriewechsel, es wird per USB-C geladen! Top!Preis/Leistung und Nutzen passt hier, von daher gibts eine klare Kaufempfehlung.

I am very impressed and very pleased with this Body Mass Scale after having used it several times. Anyone interested in their health and fitness status will find this device invaluable. Each weigh-in provides not only an accurate weight but 13 additional measurements which are extrememly useful in measuring one’s fitness and incremental progress. Graphs are provided for each parameter measurement showing percentage increase or decrease since previous measurement. A fantastic device. Easily connects to one’s smart phone and transfers all data results for easy access to results.

Die Genauigkeit der Waage ist für den Preis in Ordnung. Magnale Abweichungen zu Abweichungen zur Waage aus der Rehaklinik.Das mit der Appkonfiguration hat mehrere Anläufe gebraucht. Die App wird nur gebraucht, wenn es Tagebuchartig mitgeschrieben und optisch angezeigt werden soll. Waage nie auf Teppich stellen, es sei dem man will 10kg näher am Wunschgewicht sein. 😉. Die Handgriffe an den 4! metallischen Stellen anfassen. 2 davon sind gut unter dem Anzeigepanel versteckt, deshalb ging die BMI Messung nicht, kam immer nur die Gewichtsanzeige. Für die Körperfettmessung länger drauf stehn bleiben, geduldig sein. Er wird das Gewicht gemessen, dann passiert ne Weile nix und dann erscheint das Männl welches durchströmt wird und dann kommen paar andere Anzeigen zu Messungen angezeigt. Wenn die Waage ca. 1min nicht genutzt wird, sagt das Display “Bye bye” und die Waage geht aus, was bei Konfiguration hinderlich war, weil die App bei mir nicht sofort das gemacht hat, was ich wollte. Daher 1 Stern Abzug. Die Waage werde ich behalten. Sie ist handlich, leicht und gut verstaubar.
