Why everyone quits calorie counting apps, and how to log a meal in 30 seconds

A food diary survives only if logging a meal costs less attention than the meal itself. In practice that means half a minute, standing in the kitchen, one hand holding a fork. Everything in Zru & Hudnu is built around that budget, and the fastest tools are free.

Point the camera at any package and the product lands in your diary with calories and macros filled in. The app keeps a history of everything you have scanned, so your usual yogurt or protein bar is one tap away next time. And yes, the scanner is free. We think charging for the most basic logging tool is how apps end up with one star reviews.

Homemade granola from the market, imported products, a bag without a code: snap the nutrition table itself and the app reads the numbers straight off the photo. No squinting at tiny print, no manual typing, no math per 100 grams.

This is where most trackers give up and you are left guessing. In Zru & Hudnu you photograph the plate, and the app recognises what is on it: the toast, the salmon, the avocado, even the chips on the side. Each item comes back with an estimated weight and macros, you fix anything that looks off, and add all of it in one tap.

The AI chat takes plain human language, typed or spoken. Say two eggs and a coffee with milk and it logs them. Say I ate a frankfurter, about a hundred grams, and it finds the product, estimates the numbers and files it into the right meal. Voice input turns logging into something you do while wiping the counter.

Three meals, three quick captures, maybe one voice note. Under two minutes a day in total. The diary stops being a project and becomes background, which is the only way any habit survives past February.
