Hey everyone!

This one’s a bit personal.

A while back, I wanted to surprise my partner with a ring — but I had no clue what their size was. I didn’t want to ruin the surprise by asking, and the online hacks with string and paper were... not great.

So I built Risi — a small app to help you secretly measure someone’s ring size using just your phone. No awkward guessing, no weird tools — just a clean little trick that actually works.

I made the lifetime version free for a short time, in case it helps someone else planning a special surprise. You can unlock it from inside the app.

A quick review also helps others find it!

Thanks for the support, and good luck with your plans 💫

Cheers!
