I gave a Fitorb ring as a gift

I gave a Fitorb ring as a gift. Unfortunately, the chosen size was not right. However, exchanging it for the correct size was completely straightforward and hassle-free. I would buy from Fitorb again at any time. Many heartfelt thanks!

A good ring at a good price

A good ring at a good price. The measurements are accurate, the design is simple but attractive and, at least for my taste, it is much more comfortable than a smartwatch. Especially at night

Verified review

Fantastic

First of all, I have to say that the sizing rings are very good: they have no sharp edges like those from other suppliers and are very unobtrusive to wear.
Then my ring arrived and, thanks to that, it fitted perfectly. […]

FAQ

Your questions. Our answers.

What is my ring size?

Already know your Fitorb size? Select it directly. Unsure? Order your ring with the free sizing kit, containing 8 rings in sizes 6 to 13. Try them at home and submit your size using the link included in the package.

Do I have to pay for the app?

No. The Fitorb app is free to download and use. There are no monthly subscription fees.

Neptun or Saturn: which ring is right for me?

Neptun is 7 mm wide, has a smooth outer surface and also measures temperature. Saturn is 8 mm wide and has a groove; this model does not measure temperature. Both offer the other main features described here.

How long does the battery last?

A single charge can last up to 7 days. Actual battery life depends on usage and measurement intervals. The case lets you recharge your ring on the go for up to 21 days in total.

Can I shower, swim, or go to the sauna with the ring on?

The ring has IP68 and 5 ATM water resistance. Read the safety instructions for showering, swimming and especially high temperatures or temperature changes. Our customer support team can help with questions about specific uses.

Which phones does the ring work with?

The ring works with common iPhone and Android smartphones. Find the correct app using the QR code in the instructions. The app also offers an optional connection to Apple Health.

Do I always need to carry my phone?

No. The ring stores recorded data internally. When it reconnects to your phone and the app, the data can be synchronised.

Is the ring a medical device?

The Fitorb Smart Ring helps you better understand your sleep, activity and recovery in everyday life. It does not diagnose conditions or replace a doctor. Use the displayed readings as personal guidance.

At first I could not decide between the variants, so I ordered 3 straight away. They are all very high quality and beautifully finished. Connecting them to the app is incredibly easy, and after one week of use the recorded data seems very accurate.

I am absolutely delighted with the Fitorb Smart Ring! 😍 The features are very precise, especially the sleep and heart rate tracking, which really impressed me. What I find truly brilliant, though, is the included ring sizing kit — finally a manufacturer that thinks ahead! I could try out the perfect size beforehand, and now the ring fits like a glove. Top quality, great design and thoughtful down to the last detail. 👍

I was looking for a tracking tool without a display so I would not be constantly distracted. This product is excellent! It not only looks good but also does its job.

The ring easily keeps up with my husband’s Apple Watch. The only difference is the price.
