Ringmatch by Tom Peirs
Most customers don’t know their ring size, so they guess — and guesses often lead to returns. Ringmatch helps them measure accurately instead. Simply hold any bank card against the screen to set the scale, then align a circle with the ring they own. The app compares the measurement to the sizes you actually sell, showing which size fits and whether it’s in stock. The process is completely private: no data is stored or sent, and the app never accesses your products, customers, or orders.
How it works
- Place a bank card flat against the screen to establish a reference scale
- Align a circular ring with the screen to measure its size
- The app calculates the size and matches it to your available sizes
- Customers see which size fits and whether it’s in stock

FAQ
Can I use Ringmatch with any type of ring?
Yes, Ringmatch works with any ring that has a circular shape and can be aligned against the screen.
Does Ringmatch save or share my customer’s data?
No, Ringmatch does not store or send any customer data. The app only uses the measurement for size matching and does not access your products, customers, or orders.
Is the measurement accurate for all ring sizes?
The measurement is accurate based on standard ring sizing. It compares the result to the sizes you actually sell, so it reflects what’s available in your inventory.

I used Ringmatch to find my perfect ring size after years of guessing. It was quick and easy — just held my card and ring against the screen. The result matched exactly with what I had in my collection. No returns, no stress.

Finally a tool that helps customers measure without guesswork. I showed it to a friend who had trouble finding the right size. She found her perfect fit in minutes. Very reliable and private.

Works well for measuring, but the screen alignment can be tricky if the ring is not flat. Still, it’s a solid solution for avoiding returns and helping customers make informed choices.
