THE OFFICIAL AIFE RING SIZER​

Get Your Perfect Fit—Before You Buy Your AIFE R1

Guess wrong, and you're looking at a 7+ day wait for an exchange. The official AIFE Ring Sizer removes that risk with a simple 2-night test,  so you order once and order right.

HOW IT WORKS

Step 1 —
Test the sample rings on your index, middle, or ring finger. Pick the one with a snug fit and no gap.

Step 2 —
Sensor bumps should sit on your palm side. The ring shouldn't rotate. That's how you know it's stable for 24/7 tracking.

Step 3 —
Scan the QR code in your kit and submit your size. Your AIFE Executive R1 arrives within 7 working days. Download the AIFE app, connect your ring, and you're tracking.

Left or right index finger—your choice

Whether you choose your left or right index finger, AIFE delivers the same intuitive experience. Most users prefer their non-dominant hand for uninterrupted daily activities, but the choice is entirely yours.

Wrong Size = Wrong Experience

  • A smart ring isn't like a regular ring. For AIFE R1 to track your heart rate, SpO2, sleep, and activity accurately, it has to sit snug — not loose, not tight.
     

  • Order too big, and it slides around, throwing off your health data. Order too small, and it's uncomfortable — or a 7+ day wait for an exchange.

  • Old jewelry sizes, finger swelling, and dominant-hand differences all throw off guesswork — which is why sizing is the #1 reason for smart ring returns. Skip this step, and odds are you'll be the one re-ordering.

The fix: measure properly, once, with a tool built for this exact job.

Trusted Before the Ring Even Arrives

I would've ordered a size 9 out of habit from my old rings. Turns out I needed a 10 ,  this kit caught it before I made an expensive mistake

Aditya R., Bengaluru

As someone who's ordered the wrong ring size online before, this was the first time I felt confident before checkout instead of after unboxing.

Neha S., Ahmedabad · Verified Buyer

The two-night test felt like overkill at first, but by night two I could actually feel the difference from my first pick. Glad I didn't rush it

Ananya K., Pune · Verified Buyer

Scanned the QR, submitted my size, and the R1 showed up already fitting right. No back-and-forth, no exchange

Rohan K., Delhi, Verified Buyer

Simple kit, clear instructions, no guesswork. Took less effort than I expected for something this important.
