- Jacqueline5.0 out of 5 stars Informative and Easy to UseReviewed in the United States on September 17, 2025Color: blackVerified PurchaseI 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.
One person found this helpfulHelpfulReport - Amy W.5.0 out of 5 stars niceReviewed in the United States on September 11, 2025Color: blackVerified Purchasereceived my scale yesterday. I was excited to try it out and see what kind of data it would provide. Right out of the box, it was fully charged. The Starfit app was very simple to set up and get dialed in with my info and goals. The Scale itself is stout and well-built, with no loose parts, making it a nice and solid scale.
Turning it on and watching it come to life was a simple process. I put my phone next to the table, opened the app, as the instructions state.
You step on the scale with bare feet, ensuring your feet cover the metal pads on the scale. You hold the handle part as instructed, making sure your thumbs are on their metal pads and all four fingers are on their metal pads. You step on the scale with one foot to activate it. When it shows 0.00 in the window, it is ready for you to step on. Hold your arms in the correct position. The scale will take your weight very fast, then about 4-5 seconds after, your phone will start to play some music (you can turn this off), the handheld screen will show a person’s body with the energy waves going through the arms, legs, and body. Maybe 15 seconds and then the music stops, you can relax your arms and watch the screen, it will show you a bunch of data over the next 10 seconds if you want to watch it. If not the app will have an amazing report for your to view, More data then you can imagine. Honestly, some real solid information all well presented and logical order. Some of it was like a Blood test, with your numbers and the range of normal numbers as well as a graph of where you are on the scale. The report is very informative and can be printed on a single page of paper as well as tracked in the unit.
Yea, I am inpressed and excited to see how my body changes, not just my cloths fitting better but no muscle loss or minimual muscle loss and plenty of body fat lost.
best purchase so far. I will update in 30 days and then again at 60 days.
Read more7 people found this helpfulHelpfulReport - Eric O.5.0 out of 5 stars Awesome Scale!Reviewed in the United States on September 15, 2025Color: blackVerified PurchaseThis smart scale has completely upgraded how I track my health! The setup was quick and easy — the app connected to my phone in seconds, and I had my first reading within minutes.
What makes this scale stand out is the 8-electrode system with the retractable handle. It measures your full body, not just through your feet, which makes the results feel more accurate and comprehensive. It gives you 28 different body metrics — weight, BMI, body fat %, muscle mass, bone mass, water %, and more — and shows the 7 most important ones right on the handle’s bright, colorful screen so you don’t even need your phone to see your progress immediately.
The Starfit app is easy to use and keeps all your data organized, letting you track changes over days, weeks, and months. It even syncs with Apple Health and Fitbit, which is great for keeping everything in one place. The platform feels sturdy, the handle slides in and out smoothly, and the whole design is sleek enough to leave out in the bathroom.
I love that it’s FSA/HSA eligible, so it can be covered as part of my health benefits. This is a must-have if you’re serious about tracking your health beyond just weight — highly recommend!

Valdez4.0 out of 5 stars BMR inaccuracy but overall good scaleReviewed in the United States on July 13, 2025Color: blackVerified PurchaseThis scale is great but I had to return it because it does not calculate BMR correctly, I know my BMR give or take using the BMR formula, including my own personal method by heart rate and or simply going online using free calculators to determine range of BMR. All 3 methods were in range but with this scale it was way off about 800 calories, I did go back to see if i may have entered my height or age incorrectly but everything was good. I though the scale would give me a BMR reading on demand without having use the other methods but because of the price of the scale you might want that feature to function properly. Other than that it is great scale just wasn’t for me.

Ted K.5.0 out of 5 stars Easy to useReviewed in Singapore on September 29, 2024Color: blackVerified PurchaseWorks right out of the box. Easy to set up and use for multiple people. Information is clear and seems quite accurate.
Report- Andreas R.5.0 out of 5 stars Eine sehr gute Wahl.Reviewed in Germany on September 3, 2025Color: blackVerified PurchaseEin 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.

Michi5.0 out of 5 stars Präzises MultitalentReviewed in Germany on August 8, 2025Color: blackVerified PurchaseFazit 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.

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.
Report - frager4.0 out of 5 stars Waage, fast so genau wie eine ProfessionelleReviewed in Germany on August 14, 2025Color: blackVerified PurchaseDie 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.
