Nutrition apps and supplements, tested on a real grocery budget
We signed up for six of the brands people in the US actually pay for, logged our own meals and took the supplements for weeks, then ranked them on how they held up once the novelty wore off.
The six, side by side
Ordered by how each one performed in our testing. The price column is what you would actually pay in the US; tap a name for the full write-up.

Our pick, three ways
No single app fits every eater, so here is the call depending on what you want from one.
MyFitnessPal
4.8 / 5- A food database wide enough that almost anything you eat is already in it, barcode and all.
- Logging settles into a few seconds per meal once your regulars are saved.
- The free plan covers calorie tracking, so you can run it for a fortnight before paying.
Lifesum
4.4 / 5- A clean, encouraging interface that does not bury you in numbers on day one.
- Ready-made meal plans give you a path to follow instead of a blank diary.
- The free tier is enough to learn the habit before deciding to upgrade.
Cronometer
4.7 / 5- At ten dollars a month it undercuts the headline trackers while doing more.
- Full micronutrient breakdowns that the cheaper apps simply do not show.
- A capable free plan, so the upgrade is a choice rather than a wall.
What the testing adds up to
A rough sense of the work behind the ranking, and the one number we never lose sight of.
How we rank
We do not lift bullet points off a product page. Every brand goes through the same stretch of real use, scored on the same eleven points. Here is the order it happens in.
We pay like a normal customer
No press accounts. We buy the subscription or order the supplement ourselves, so what we see is what you would see signing up today.
We live with it for weeks
An app gets at least three weeks of daily logging across busy days and lazy ones. A supplement runs long enough to judge routine and tolerance, not a first-day impression.
We read the data policy
Food logs are personal. We note what each brand collects, what it shares, and which settings let you switch tracking off.
We score on one sheet
Every brand is judged on the same eleven points, so a ten-dollar tracker and a fifty-dollar synbiotic are weighed on what they set out to do.
What we leave out
- Health claims about cleansing or weight loss we cannot observe across a few weeks of ordinary use.
- App-store star averages and influencer round-ups copied into a list.
- Anything a brand would only let us see through a sponsored arrangement.
Questions readers ask
Affiliate links keep the lights on. If you sign up or buy through one of ours, the brand may pay us a commission. It changes nothing about the order of the list and costs you nothing extra.
We last refreshed it on May 17, 2026. We revisit a brand when it changes its price, plan or formula, and the date sits in the byline on every review.
Lifesum, in most cases. It eases you in with guided plans instead of an empty food diary. If you would rather pay nothing yet, the free tier of MyFitnessPal also asks very little on day one.
Trackers get a minimum of three weeks of daily use. Supplements run for several weeks so we can judge the routine and how our bodies settled with them, rather than a single dose.
They do, because readers weigh them against each other when budgeting for nutrition. We score each on its own terms and say plainly which problem it solves, so a multivitamin is never judged as if it were a calorie tracker.
We do not publish crowd-sourced stars. Every score comes from our own desk using the product, so there is no rating pile for a brand to game.
We keep the list to brands we have tested properly. If a name you expected is not here, it usually means it is on the queue, not that we rated it badly.
Email info@dynvybrightir.world with the page and what looks off. If a price or formula has changed, we check it against the brand's current US site and update the review.
