femometer Smart Ring Sizing Kit : Ensures perfect ring fit
Here's the lowdown on how to nail the perfect fit:
- First things first, grab a sizing kit. It's like a test drive for your finger.
- Once you've found your match (and yes, it might take a day or two of wearing the sizing ring to be sure), go ahead and order your actual Femometer Ring.
- Next up, download the Femometer app. It's the brain of the operation, turning your ring into a powerhouse of insights.
- And here's the cherry on top: buying the ring gets you a lifetime pass to the Femometer App. No subscriptions, no fuss.
A little pro tip: don't rush the sizing process. Wear the kit for a full day to really get a feel for it. Made from tough, high-quality plastic, these sizing rings are built to last—so you can take your time making the right choice.
