Point your camera at a price tag, menu, or receipt to see an estimate in your own currency. Kahei reads one printed price at a time and works offline from your first scan with built-in reference rates. You can also type an amount and revisit recent scans. Free on iPhone and Android, with no ads or account.
Hi, I’m Max. I built Kahei because I kept doing the math in my head or Googling prices every time I traveled. Waiting for a page to load on a slow connection felt like a lot of work just to check a menu price.
With Kahei, I can point my camera at one printed price and see an estimate in my own currency. It works in airplane mode, and it’s free on iPhone and Android.
If you try it on a menu with several prices close together, I’d love to know whether it picked the one you meant.
