Qalzy

What it is

Qalzy is a London-based AI nutrition scale built by Kostas Koukoravas and Michael Michelis. A camera-equipped kitchen scale identifies the food placed on the glass, weighs it to the gram, and logs calories, macros, and key micronutrients at the press of one button, cross-referencing a database of 2.9 million verified foods from USDA and the UK's CoFID sources. It works standalone with unlimited scale-based AI scans and no subscription required, and pairs with a companion app that can also read food photos and surface glucose-response data from Apple Health or Google Health Connect.

Who it's for

Anyone tracking calories or macros who has abandoned phone-based logging apps because typing or photographing food mid-cook is too much friction, and founders building any product where a photo or manual estimate quietly fails at accuracy.

Why it's better

• •Weighs food to the gram instead of estimating portion size from a photo, closing the gap researchers say causes AI photo-logging apps to miss quantity by as much as 65%.
• •Zero phone required at the moment of use, one button press while your hands are still on the food, which its founder says drives roughly 60% higher long-term compliance than app-only logging.
• •2.9 million verified foods pulled from USDA and the UK's CoFID database, not crowd-sourced entries of unknown accuracy.
• •Built and funded backwards from a six-figure Kickstarter campaign, so features like 9-profile multi-user support and glucose-response tracking shipped because backers asked for them, not because a roadmap meeting invented them.
• •Ships with a 30-day money-back guarantee and a one-year warranty, plus the same food-recognition AI free inside the app before you ever buy the hardware.
