Calorie tracking, in your own words.
Type what you ate, snap your plate, or ask Siri. Noxy gives you a calorie and macro estimate to check, so logging a meal fits into your day.

An everyday habit
Calorie tracking that fits into your day
Logging a sandwich shouldn’t take more attention than eating it. Noxy starts with the meal you remember, in the words you’d actually use.
Describe it, photograph it, or ask Siri. Review the estimate and its sources, adjust anything that looks off, and confirm. Your meal is added to your day, with calories and macros together.

Ways to log
Three ways to log a meal
Choose the method that fits the moment. Each one ends with an estimate you can review and edit.
Chat it
Type the meal the way you would tell a friend.
Two eggs, toast and a flat white is enough. Noxy identifies each item, uses nutrition sources, and returns calories with protein, carbs, fat and fiber plus a confidence score.
Snap the plate
Photograph the food instead of describing it.
Useful for a plate with several things on it, or for a meal you would struggle to name. You still see the estimate and can correct the portion before it saves.
Ask Siri
Hands free, without opening the app.
Say Hey Siri and log the meal out loud. The estimate appears in the Dynamic Island for you to confirm, which is the difference between logging on the walk home and forgetting by dinner.
You confirm every estimate before it becomes part of your food journal. See each path running on a phone.
Each day
What you get back
- Today's balance
- Calories left for the day, with protein, carbs, fat and fiber underneath so a macro target is never a separate app.
- A readable journal
- Meals in the order you ate them, with a note at the end of the day. It reads like a diary, not a spreadsheet.
- Sourced estimates
- Each estimate shows where the numbers came from and how confident it is, so you can tell a solid entry from a rough guess.
- Watch your streak grow
- Days in your calorie target zone grow your streak and brighten your campfire through ten flame stages.
Honestly
About accuracy
Every calorie number anywhere is an estimate.
Food labels carry a legal tolerance, restaurant portions vary by whoever plated them, and two apples of the same weight are not identical. AI does not fix that, and neither does a barcode.
What makes tracking work is consistency. If you log the same way every day, the errors stay roughly constant and the trend across weeks stays honest, which is the part you actually make decisions from. Noxy is built for that: it shows you the sources, shows you a confidence score, and never saves anything until you confirm it.
Not sure what your target should be? Start with the free TDEE calculator or the macro calculator, then track against it.

What is an AI calorie tracker?
An AI calorie tracker turns a plain description or a photo of your food into an estimate of calories and macronutrients, instead of asking you to search a database and pick a portion size. With Noxy you write or say what you ate, and the estimate comes back with its sources and a confidence score for you to confirm or edit.
How accurate is AI calorie tracking?
Every calorie estimate is an estimate, whether it comes from AI, a barcode or a food label. Noxy shows nutrition sources and a confidence score, and lets you correct the portion before it saves. Consistency matters more than precision: tracking the same way every day makes the trend reliable even when a single meal is a few percent off.
Can I track macros as well as calories?
Yes. Every logged meal breaks down into protein, carbs, fat and fiber, and the home screen shows what is left of your daily target for each one.
Does Noxy work without typing?
Yes. You can photograph a plate, or say Hey Siri and log a meal hands free. Siri shows the estimate in the Dynamic Island so you can confirm it without opening the app.
Is Noxy free?
Noxy comes with a 7-day free trial, and after that it needs Noxy Pro. The macro and TDEE calculators on this website are free to use with no account.
What phones does Noxy support?
Noxy is an iPhone app, available on the App Store. There is no Android version yet.
Do I have to log every single meal?
No. Most people get the benefit from logging the meals they are least sure about. The daily balance still adds up, and the streak only asks that you land in your calorie target zone.
