Eric Migicovsky has been thinking a lot about friction. Specifically, he’s been thinking about how too much friction in the way of using a device can put people off wearing it altogether. The founder of Pebble is here at CES 2026 with a few new devices from the company he recently started to bring back the beloved smartwatch brand, including the Pebble Round 2 and the Index 01. That second one is a simple ring with a button on it that you push down to talk to Pebble’s AI whenever you want it to help you remember something.
In the sea of AI gadgets that clutter the showfloors of CES (and the current tech industry in general), the Index 01 is refreshingly simple. The prototypes I saw here in Las Vegas weren’t connected to phones, so they weren’t actually working. They also seemed a little unfinished, like there was still some polishing to do. But I was able to put a few on and push their buttons. I also checked out the one Migicovsky wears — more on that in a bit.
I have to caveat that the rings that Migicovsky and his team had for us to try on were way too large for me. I did manage to get sized and found out I was a Pebble size 7, while my colleague Dan Cooper was determined to be a size 11. These demo rings sat loosely on my finger — and Migicovsky was particular that I wear it on my index finger and not my thumb or middle finger.

I suspect that has to do with how you reach for and press the button. It’s much easier to push the key if it’s closer to your thumb. Since the idea of the Index 01 began as an app on the Pebble watch, Migicovsky has been working hard to figure out how best to make it easy to access. Back when it was an app, “friction points were having to use your other hand” to press the screen, he said. “We also experimented with gestures and voice activation, wake words,” he added. But as many of us are painfully familiar with, those triggers don’t always work well.
“The whole thing that drives this ring is it being something that you can rely on. It being something that you can incorporate into your… habits,” Migicovsky said. So putting a button right by your thumb not only makes sense, but might even be, in my opinion, a bit more accessible for people with, say, speech impediments or only one hand.
I have to admit I initially found the Index 01’s design to be a bit bulky-looking, and the rubbery button protrudes a lot more than I expected from looking at it in its glamor shots. It’s like in place of a diamond or a gemstone on the ring, there’s a weird little nipple that you twiddle around until you want to push it.
I did find the button easy to press, if that allays any of your concerns at all. But, really, the Index’s powers aren’t visible. It’s what happens after you push the button that matters.
