About KalTrack

Last updated 2026-11-11

KalTrack is an iPhone calorie and macro tracker that estimates a meal's calories from a photo as a range with a best guess, and reads barcodes and nutrition labels exactly. This page says who makes it, and how the guides on this site are put together, so you can decide how far to trust them.

Who makes KalTrack

KalTrack is made by Viral Labs, a small independent app studio run by Viral Tandel, who designs and builds the app and writes and edits this site. On the App Store the developer is listed under his own name, Viral Tandel; it is the same app and the same person. Viral Labs has its own site at virallabs.app.

There is no larger company behind KalTrack, no investors to answer to, and no advertising on this site. The app makes money one way: people who want more than the free plan subscribe to KalTrack Pro. The free plan includes 3 AI scans a day, and barcode lookups are always free.

Why it exists

Most calorie trackers ask you to search a database and weigh every ingredient, and most people stop within a couple of weeks. KalTrack starts from a photo instead, and says plainly that a photo gives an estimate, not a measurement. That is why it shows a range with a best guess rather than one confident number, and why the accuracy page explains where photo estimates go wrong.

How the guides are researched

• Every calorie and nutrient figure has a named source. Food figures come from USDA FoodData Central, cited by FDC ID at the foot of each post, or from a restaurant's or manufacturer's own published nutrition, with the date it was retrieved. If neither source publishes a figure, the post says so instead of guessing.
• Portions are never invented. A per-serving number appears only when USDA or the brand publishes that portion weight, or when the arithmetic is shown so you can redo it with your own weight.
• Health guidance is cited to its origin, such as the National Academies' Dietary Reference Intakes for protein, rather than repeated from other blogs.
• Comparison pages are written by the maker of one of the apps compared. Each one says so above the first entry, and KalTrack is never ranked first while it has fewer than 25 App Store ratings.

How AI is used

Drafts of the blog posts are written with an AI writing assistant, working from the sources listed on each post and from a written set of house rules. Figures are checked against their sources, and the build that publishes this site rejects any post that breaks the rules, for example a nutrition table with no sources or a missing not-medical-advice line. Viral sets the plan and the rules, and is responsible for everything published here. The calorie figures themselves never come from an AI: they come from USDA or the brand.

KalTrack the app uses AI vision models to estimate the food in a photo. That is the product, and it is described honestly on the accuracy page.

What this site is not

Nobody on the KalTrack team is a registered dietitian or a clinician, and the guides have not been reviewed by one. They are careful, sourced explanations of food data, written for people who want to understand what they eat. They are not medical advice, and KalTrack is not a medical device. If you have a clinical reason to track intake precisely, work with a dietitian or your doctor.

Corrections

If you find a figure that does not match its source, or anything else that is wrong, email viral.b.tandel@gmail.com. Corrections are made on the page, and a post that changes materially shows the date it was updated.
