Calories logging from meal photos – Oura’s AI Brilliance

I recently covered the likely direction for Oura’s hardware as they release Ring 4 later this year.

However, Oura‘s ecosystem extends beyond the market-leading ring to its app. It looks like the app is about to include two new headline features, one being groundbreaking if it can get the calorie count correct.

Feature 1 – Heart Rate Zone Tracking.

This feature builds on widely used sports science from heart rate, exemplified by Apple Watch’s move to cover Training Load in the latest watchOS 11.

TL;DR – Accurately taken heart rate during sports can be weighted and averaged over a few weeks to give a modelled view of your fatigue. Put that against overnight HRV from the Oura Ring and you get an excellent view of what your body can handle.

Feature 2

Oura’s excellent app will let you take pictures of the meal you’re about to eat. Great. But then it will use AI to determine what’s in the meal and approximate the number of calories. That will be a GREAT boost to calorie trackers…if accurate.
