AI SCANNER
What an analysis looks like in the app (example)

It's not calorie counting.

Without obsessing over every number.
AI SCANNER
One photo and done. No weighing, no logging.
One photo. Your numbers, right here.
Take or pick a photo of your plate and see the analysis on this site: calories, macros and what it recognized. No account needed.
Or drag a photo here
Three steps. Zero friction.
Your plate, your meal prep or a barcode. The AI recognizes every food and estimates its amount.
Calories, macros and protein in about 15-25 seconds, with a confidence level. Fix anything you want.
Renzy compares what you have eaten with your daily goal and tells you how many calories you have left today.
Logging by hand or snapping a photo.
Search every food in a list, weigh or guess the grams and add it all up. It works, but it takes time at every meal.
One photo and you get an estimate for each food, which you fix if needed. If you work with a dietitian, it doesn't replace them: it helps you keep the log they ask for. Or on the yearly plan, which works out cheaper per month.
Photo, barcode, goal, progress. No app-hopping.
From your own data: calories, protein, carbs and fat.
Packaged products come up right away. What you cook, with a photo: the AI recognizes every food and estimates its amount.
Checked against BEDCA, USDA and Open Food Facts.
It adapts to your goal.
Your calories and protein change depending on whether you want to lose, maintain or gain weight, and you pick your sport. Not one generic number for everyone.
A small calorie surplus and more protein.
More carbs in your split, and a little less fat.
A moderate deficit with protein kept high.
Your maintenance calories and a balanced macro split.
Built for the food you actually eat.
From a burger patty to a bagel, the AI recognizes each food and checks the values against reference data from USDA FoodData Central, BEDCA and Open Food Facts.
Approximate values for the serving shown, from our reference database.

Your weight, without the day-to-day noise.
You log your weight and Renzy draws the trend, not the noise of a single day. You see it next to your daily calorie and protein goal, week after week.
- A trend built from every weight you log
- Your daily calorie and protein goal alongside
- A summary of every week
The line uses every weight you have logged, not just the last one. That is the trend, not the noise.

The reasonable doubts.
Is the photo analysis accurate?
It recognizes common dishes well. The hardest part is the amount, which is estimated from the photo, so every result comes with a confidence level and you can correct any value before saving. We publish the average error, misses included.
See the accuracy pageDo I need a card to try it?
Yes. A card is required to start the 7 free days, but nothing is charged during the trial: cancel before it ends and you pay nothing. Want a look first? The web scanner works with no account and no card.
Does it work offline?
No, the app needs a connection — history and weight included. The one safety net is scanning: a photo taken with no signal stays on your phone, ready to analyse in a tap once you're back.
What happens with my data?
Photos are stored encrypted and tied to your account, for your history. We never sell or share them. They only enter our training set if you switch that on in Settings. You can delete your account and all data in one click.
Can I cancel the subscription?
Anytime, no questions asked. You keep access until the end of the paid period.
Is there an iPhone and Android app?
Yes, both: Renzy is on the App Store and Google Play. On a computer, the download page has a QR code to open it on your phone.
Does it calculate my macros by sport?
When you start you pick your goal (lose, maintain or gain weight) and your sport. Renzy sets your calories and protein from your goal, and your sport changes the split: if you do strength training, protein stays high even when maintaining; if you only do endurance, you get more carbs. You can change them anytime.
Does it work for strength or endurance?
Yes. Your targets depend on whether you want to lose, maintain or gain weight, whatever your sport.
