As a Type-1 Diabetic, counting carbohydrates is integral to diabetes management.
Most foods have the total carbohydrates per 100g or per serving on their nutrition label, so it’s often a trivial calculation. For the other foods I commonly eat, I’ve made this simple Progressive Web Application using Vue.js to calculate the carbohydrates in my portion.
As this is a Progressive Web Application, besides being accessible in the web browser, it’s installable on my phone. I use this multiple times a day from my phone.
If you want to try the Carbs Calculator out for yourself, you can find it on carbs.omgmog.net.
