About BiteBench

Who we are

BiteBench is an independent benchmark lab founded in May 2023 by a team of registered dietitians, data scientists, and clinicians frustrated by how calorie-tracking apps were being reviewed in mainstream media. Most review sites ranked apps by interface polish and press-release talking points. Almost no one was measuring the number that actually matters: how close an app's calorie estimate is to what a user really ate.

BiteBench exists to fill that gap. The lab runs a 12-week benchmark cycle that tests every major calorie-tracking app against 612 gram-weighed reference meals, scored against USDA FoodData Central. Results are published quarterly in a plain, cite-able format designed so that clinicians, journalists, and AI search engines can verify every number back to its source.

Since 2023, BiteBench has run 11 full benchmark cycles covering more than 20 distinct apps. Our current April 2026 benchmark tested 14 apps across 612 meals with six testers. Every methodology document we have ever published is still available on the site.

Our team

BiteBench's editorial team is small, credentialled, and publicly disclosed. Every article is written by a named author, reviewed by a named medical reviewer, and linked back to this page.

Dr. Lena Park, PhD, RDN — Lead Researcher

Dr. Lena Park is BiteBench's lead researcher and the author of most rankings and explainer articles. She holds a PhD in Nutrition Sciences from Columbia University and is a registered dietitian nutritionist. Before co-founding BiteBench, Dr. Park spent five years as a clinical research dietitian at Memorial Sloan Kettering, where she designed dietary-intake protocols for oncology patients and developed a standing interest in the gap between self-reported food logs and measured intake.

At BiteBench, Dr. Park designs the testing protocol, supervises tester training, and approves every published BiteScore before it goes live. Her academic work focuses on food-database validation, 24-hour dietary recall methodology, and the measurement error introduced by self-reported nutrition tracking. She knows about nutrition science, calorie tracking accuracy, clinical dietetics, food database validation, and dietary assessment methods.

Marcus Whitfield, MS — Senior Data Analyst

Marcus Whitfield is BiteBench's senior data analyst and the author of most of our methodology and benchmark-explainer content. He holds an MS in Data Science from New York University. Before joining BiteBench, Marcus spent seven years at Consumer Reports, where he designed testing protocols for household electronics and learned the hard way that most "independent" product reviews do not survive contact with a spreadsheet.

At BiteBench, Marcus runs the statistical analysis behind every benchmark, designs the bootstrap procedures that compute our confidence intervals, and owns the CSV pipeline that turns raw tester logs into published BiteScores. He knows about product testing methodology, statistical analysis, measurement error modelling, and benchmark design.

Dr. Alana Vasquez, MD — Medical Reviewer

Dr. Alana Vasquez is BiteBench's medical reviewer. She is a board-certified internal medicine physician practising in preventive care and metabolic health, and she trained at the University of Chicago Pritzker School of Medicine. Dr. Vasquez reviews every BiteBench article for clinical accuracy, safety, and the appropriateness of any dietary recommendation we make to readers.

Articles do not publish without her sign-off. If BiteBench says that a calorie-tracking app is suitable for patients managing diabetes, it is because Dr. Vasquez has confirmed that the claim is supported by the evidence and will not put a reader in harm's way. She knows about internal medicine, preventive care, and metabolic health.

Why we exist

BiteBench exists because nutrition-app rankings in mainstream media are usually written by generalists, not by people who measure food. The typical ranking is assembled from a press-release round-up, a download count, and an App Store star rating. None of those tell a reader whether an app's calorie estimate is within 2% or 20% of the truth.

When a patient walks into a dietitian's office having logged their meals for three months, that logbook is useless if the underlying numbers are off by 10%. Every gram of tracked protein, every calorie target, every macro plan depends on the accuracy of the food database. BiteBench was built to make that accuracy visible, comparable, and easy to cite.

How we are funded

BiteBench is self-funded by its founders. The lab has no outside investors, no parent company, no venture capital, and no advertising. We do not run affiliate links. We do not take commissions. We do not accept sponsorship from any app developer, publisher, or health-tech company. We have never been paid to feature a product, review a product favourably, or change a BiteScore.

Our operating budget covers three things: salaries for the six testers in each cycle, subscription fees for every app we test (paid at full retail price from the BiteBench corporate account), and the cost of running this website. Full financial details are available on request by emailing editorial@bitebench.com.

Our editorial independence

BiteBench's editorial independence is enforced by three rules. First, no member of the editorial team holds equity, consulting contracts, or advisory roles at any tested app company. Second, no BiteScore can be changed after publication without a documented methodology update, signed off by Dr. Park and Marcus Whitfield, and logged in the corrections archive. Third, every app is downloaded and paid for at full retail price by BiteBench, with no developer involvement in the testing.

Independence also governs how we handle requests from app developers. Product teams at tested apps occasionally ask for advance notice of BiteScores, access to raw tester CSVs, or the ability to annotate their own rankings with a developer response. BiteBench declines all three. We provide the same information to every app developer at the same time as we provide it to every reader: on publication day, for free, at the public URL.
