A fraction of the price.
Smart rings cost several hundred dollars, and some of them keep charging every month to unlock measurements your own finger took. Summit is $99, once, and never asks again.
All prices in CAD. Over 3 years Summit is $380 cheaper than the nearest of them, and every feature stays switched on for as long as the hardware lasts.

Customer Feedback
From real wearers.
“I can't take this ring off. Every night it's helped stabilize my routine, it's light, and it feels like a premium piece of jewelry. People always ask me how much it cost and about subscriptions since it looks like the name brand rings. I'm always happy to tell them it's private, on-device with no sub, only a 1-time payment. I love the insights and personalization. It feels like a part of me, not some generic tech. I would suggest everyone, not even just health and fitness gurus, try it to better their sleep and activity.”
Get the size right first.
It is worn every day and it does not adjust, so this is the one detail worth two minutes. Measure at the end of the day, when fingers are at their largest.
How to measure your ring size at home
- 1Wrap a strip of paper or a length of string around the base of the finger you will wear the ring on.
- 2Mark where the end overlaps, so the loop is snug but slides over your knuckle.
- 3Lay the strip flat and measure to the mark in millimetres. That is your finger circumference.
- 4Match the millimetres to the chart to find your US size (7 to 13).
Between two sizes, or measuring a wider knuckle, size up. Got it wrong anyway? Our 100% Free Size Exchange Guarantee covers a free swap with zero shipping fees.
Fingers expand naturally overnight and with temperature changes. A ring that feels like an exact, snug fit during the day can become uncomfortably tight while sleeping. Aim for a breathable fit that clears your knuckle with light resistance but won't slide off. If you are in between sizes, always size up.
