Frequently asked questions

Are there any subscription fees for the MYnextRING app?

No. The app is free for you forever — no subscription, no ongoing costs. You pay for the ring once, and everything else is included.

How does the MYnextRING differ from other wearables?

The MYnextRING brings together sleep quality, recovery (via HRV), stress and activity in a discreet titanium ring. The built-in AI Coach translates your numbers into clear, easy-to-understand recommendations instead of a flood of data. On top of that: no subscription and data kept in the EU.

How accurate is the ring's data?

The ring's readings are calibrated against established fitness wearables and optimised for everyday use. As a wellness device it delivers reliable trends — but it does not replace a medical measurement.

Where is my health data stored?

Your data is held on servers in the EU and processed in a GDPR-compliant way. It does not leave the European area. You can delete it yourself at any time in the app.

Is the ring waterproof?

Yes, the MYnextRING is water-resistant to 5ATM. Washing your hands, showering and swimming are no problem. We advise against wearing it in the sauna, while diving or in hot water, as heat and high pressure can strain the seal.

How long does charging take — and how long does the battery last?

The ring charges wirelessly in its charging box and is fully charged in under 2 hours (around 90 minutes). A single charge lasts up to 10 days, depending on use.

Good to know

14-day right of withdrawal — we cover the return shipping.
2-year statutory warranty under Austrian law.
No subscription: every function included permanently, AI coach too.
Your health data is stored on servers in the EU, GDPR-compliant.
SizeKit included — determine your ring size at home, at your leisure.

Ready for your ring?

Both models measure around the clock, both work without a subscription, and your data stays on servers in the EU. The difference is the design: the SKY is flatter and lighter, the N2 Pro lasts longer.

Don't know your ring size? No problem — simply place your order and we'll send you a SizeKit with sample rings first. Determine your size at your leisure and redeem the ring afterwards.
