For diets that don't count calories
Snap a photo.
Stay on your diet.
Keto, paleo, carnivore, Whole30, AIP — most trackers just count calories. RedGreen checks each item on your plate against your diet and tells you what's on plan, what isn't, and what's borderline.
Free to start • 7-day Pro trial • No calorie counting
How it works
From plate to verdict in three steps
Restrictive diets aren't really about numbers. The daily question is simpler: can I eat this?
Pick your diet
Choose from keto, paleo, carnivore, Whole30, AIP and more — or build your own by listing what's allowed and what isn't.
Snap a photo of any meal
Point your camera at your plate. RedGreen identifies the items and checks each one against your diet.
See the result in seconds
Each item gets a green, yellow, or red badge based on your diet's rules. Repeat at every meal to see your weekly and monthly consistency.
Diets
Built for restrictive diets
RedGreen supports the most common restrictive diets out of the box, and lets you build a custom one when you need something specific.
Features
What's in the app
The features that matter day to day when you're on a restrictive diet — no calorie database, no barcode scanner.
Photo meal logging
Point your camera at your meal. Each item gets a green, yellow, or red badge, checked against the rules of your diet.
Color-coded calendar
See your whole month at a glance. Each day reflects how closely you stayed on plan, making patterns easy to spot.
Weekly consistency score
Track the percentage of meals that stayed on plan each week, so you have an honest picture of how you're doing.
Intermittent fasting
Your fasting window is tracked automatically from your last meal. Set a target and follow your weekly average.
Weight tracking
Log your weight, see the trend, and follow progress toward your target alongside your meal data.
Custom diets
Following your own plan, an allergy protocol, or a specialist diet? List what's allowed and what isn't, and RedGreen handles the rest.
