That is the daily routine. You always approve the estimate yourself, and you can change it before it goes into the diary.
One picture of the food on the plate. No scales, and no searching through a database.
You can edit the estimate and choose how much of the dish you ate. When Karbi is unsure, it says so and shows a rounded, approximate number.
The entry goes into that day's diary and counts towards the daily budget and weekly statistics.
For every entry, Karbi estimates a short, medium or long absorption time. The category depends on the food's composition: how much fat and protein it contains alongside carbohydrate. There is no category below ten grams of carbohydrate.
Karbi's database holds more than 3 million products, and the search ranks products sold in Hungary first. If a product is missing, photograph its nutrition label: the values go into your entry, and the product joins the shared database. Karbi marks products other people submitted.
Log your meals, follow your daily carb or calorie budget, check your statistics, and export your log as CSV, or as PDF with the subscription.
I have type 1 diabetes, I count carbohydrate every day, and I use Karbi myself. I build it for the Hungarian diabetes community: after a meal photo, you review the estimate instead of calculating the carbohydrate content from a table. The same photo gives calories too, so it also works for anyone who tracks their calorie intake.
The 542 survey responses from the Hungarian community confirmed the need for a carbohydrate estimation app. If there is something you wish it had, send me an e-mail. I read every one.
The photo result is an estimate, so always check it. Karbi is not a medical device.
There are two packages: Karbi Free and the Karbi Photo subscription.
Try the photo estimate for free: 3 estimates without an account, 5 more with one.

Karbi compares two evaluations: if they agree, you get one number; if not, you get a rounded, approximate number and a "Worth a look" notice. The cases where the estimate is less certain are on the limits page: Limits of the estimate
The photo result is an estimate, so always check it. Karbi is not a medical device. It gives nutrition data: carbohydrate, fat, protein, calories, and a short, medium or long absorption time. Limits of the estimate
You can use Karbi for any food: a home-cooked dish, a canteen portion or a restaurant plate. For a packaged product you can scan the barcode for free (or photograph its nutrition label if the product is missing from the database), which gives you the data from the producer instead of an estimate. What the photo does not show, such as ingredients under a sauce or parts not visible in the picture, Karbi cannot see either, so the estimate can be inaccurate.
The free package has the diary, the daily budget and statistics, and scanning packaged products by barcode is free as well. If a product is missing from the database, you add it by photographing its nutrition label. Estimating a plate from a photo is part of the Karbi Photo subscription, but you can try it: 3 estimates without an account, 5 more with one, and the subscription starts with a 7-day free trial that then renews until you cancel. Prices are on the plan cards: What each package includes
Karbi is currently available on Android only. I keep working on Karbi, and an iPhone version could follow if there is enough interest. If you have an iPhone and are interested in the app, write to .
You can log without an account. Karbi does not keep the photo sent for an estimate after the response. It syncs to the cloud only if you turn that on separately. Details of how your data is handled: Privacy notice
Karbi is available in the Google Play store. If you have a question, send me an e-mail.
