NEW The calorie tracker that scores food quality
Macros tell you how much.
Macros tell you how much.
Nudge tells you how good.
Two meals can hit identical macros and be completely different food. Nudge Health gives every food you log a quality score out of 10, built from its processing level, additives and nutrient density, and puts it right next to the calories.
Free to start. No ads. No tracking in the app. Your data is never sold.

How the score works
One number. Three honest inputs.
No black box. Every score is built the same way, and you can see exactly how in the app. Or right here.
01 · PROCESSING
NOVA group
The scientific scale for how processed a food is, from whole foods (group 1) to ultra-processed (group 4).
50% of the base score
02 · NUTRITION
Nutrient density
Protein and fibre weighed against sugar, saturated fat, salt and energy, all per 100g so portion size never skews it.
50% of the base score
03 · INGREDIENTS
Additive penalty
Additives are tiered by strength of evidence: high concern −0.8, moderate −0.4, low −0.15. Capped at −3.

The honest tracker
Built to tell you the truth, not to keep you hooked.
Nutrition apps have a habit of overselling AI, burying the useful bits and quietly monetising your data. We made a list of everything that annoys people about them and did the opposite.
Scores never move
A food scores the same at 7am or 9pm, on a rest day or race day, whether you've macros left or not. No moving goalposts, no flattery.
AI is labelled as a guess
Photo and chat logging are handy, and they're estimates. We say so on screen, and you confirm or correct every item before anything is saved.
The formula is public
Processing, nutrient density, additive tiers, the weights. All of it is on this page. Tap any food in the app to see its own breakdown.
No ads. No tracking.
No advertising SDKs, no ad identifier, no selling or sharing your data. You pay for the app, so you aren't the product.
Your log is safe
Everything syncs to your account, stored in the EU. Switch or add an iPhone, sign in, and it's all there. An update will never wipe it.
Health data stays put
Apple Health is read on your iPhone and never uploaded anywhere. You can delete your account and every log from inside the app, any time.

Connect Apple Health and Nudge reads one thing: the active energy you burned yesterday. Today's calorie and macro targets adjust to match, so a heavy training block gets fuelled properly and a rest day doesn't tip you over.
It's read on your iPhone and never leaves it. Whoop and Garmin support is planned.

Questions
Good questions.
When can I download Nudge Health?
Nudge Health is launching on iPhone first, and it's coming to the App Store soon. This page will have the download link the moment it's live.
Does a food's score change if I eat more of it, or later in the day?
No. A food's score is fixed to the food itself, calculated per 100g. It doesn't change with portion size, time of day, your activity or how many calories you have left. Portions change your calories and macros; they never change how good the food is.
Where does the product data come from?
Barcode and search results come from Open Food Facts, an open database of millions of products. If something's missing you can add it yourself in the app, and we review new entries before anyone else sees them.
How accurate are photo and chat logging?
They're estimates, and the app labels them that way. Before anything is saved you'll always see what was found and can correct it. For packaged food, barcode scanning and search are the most reliable ways to log.
Can I use it on more than one device?
Yes. Your logs live in your account, not on your phone. Sign in on any iPhone and everything is there, including after app updates.
Is this medical advice?
No. Nudge Health provides general nutrition information. Scores and targets are estimates, so please speak to a healthcare professional before making significant changes to your diet.
How do I cancel, or get help with my subscription?
Subscriptions are managed by Apple, so you can cancel any time in Settings → your name → Subscriptions. Our support page covers restoring purchases, refunds and account deletion.
