I built Kahei to solve a problem I kept running into. Whenever I traveled abroad, I’d see a price and either do the math in my head or pull out my phone to Google it. It took way too long just to check a price, especially when the internet was slow. So I made a free app where you can point your phone’s camera at a price and instantly see an estimate in your currency. It works offline! It is available on iPhone and Android. If you try it on a menu or receipt, I’d love to know whether it picked up the right price. Try it: https://kahei.app/ thanks!   submitted by   /u/vasinl [link]   [comments]
