Best supplement scanner apps in the US (2026)
We pulled the live App Store numbers for every supplement scanner in the US store. Two apps have almost all the ratings, neither has shipped an update since January, and the thing that separates them is not the one the listings talk about.
Short answer: SuppCo and Prove It, in that order, and nothing else is close. They hold 43,000 ratings between them and third place has 248.
Every roundup of these apps recycles the same four names without checking anything. So we queried Apple's own store data for the US storefront and wrote down what came back.
Figures below were pulled on 19 August 2026 and they move, so treat them as a snapshot rather than a scoreboard.
What the store actually says
| app | rating | ratings | released | last updated |
|---|---|---|---|---|
| SuppCo | 4.8 | 28,106 | Sep 2024 | Jan 2026 |
| Prove It | 4.4 | 15,661 | Jan 2025 | Jan 2026 |
| InSup | 4.6 | 248 | Nov 2024 | Dec 2025 |
| Supplements AI | 4.3 | 122 | 2025 | Jul 2026 |
| Suppi | 4.3 | 96 | 2025 | 2026 |
Three things jump out, and none of them are in anyone's listing.
It's two apps and a cliff. Third place has 248 ratings against SuppCo's 28,000. That's not a crowded category, it's a duopoly with a long tail of apps almost nobody has used.
Prove It sits 0.4 below SuppCo. Across fifteen thousand ratings that gap is not noise. Both are well reviewed in absolute terms, but 4.4 and 4.8 describe noticeably different experiences, and that is the store's own aggregate rather than anyone's pick of the angry reviews.
Neither has shipped an update since January. Seven months, in a category where the whole value is a database keeping up with what's on shelves. The two smallest apps on the list are being updated more often than the two largest.
The split that actually matters
Almost every comparison talks about interface. The real division is architectural, and it decides whether your tub is in there at all.
Catalogue apps work from a curated database. You scan a barcode, it looks the product up, and it shows you what it holds for that product. When the product is in the database this is fast and pleasant. When it isn't, there is nothing to show you, and there is nothing you can do about it.
Label-reading apps work from the supplement facts panel itself. You photograph the panel and the doses are read off it. Slower by a few seconds, and completely indifferent to whether anyone has catalogued the product.
That difference is invisible until you scan something that isn't a household name. A store-brand tub, something bought abroad, a small brand, a reformulation from last month: a catalogue either has it or it doesn't.
The other thing a scan does not tell you
Every app here scores one product.
That is not the question most people actually have. A multivitamin with 2mg of B6, a B complex with 50mg and a pre-workout with 10mg are each unremarkable, and together they are 62mg against a UK upper level of 10mg a day and a US level of 100mg. Every one of those three labels is fine. The total is on none of them.
Same for interactions. Whether the iron in one product competes with the zinc in another is not answerable by scanning either.
Verdict
Ours, so weigh it accordingly, and here is the number that matters most for weighing it: Verdict has 0 US ratings. It went on the US store this month. Everything above has a year or two of head start and thousands of reviews, and no amount of writing changes that.
What it does differently is the two things above. It reads the supplement facts panel from a photograph rather than looking up a barcode, so coverage is not a factor. And it scores your whole stack at once, giving you the combined daily total for each nutrient against published reference intakes and upper levels, flagging where two products supply the same thing, and showing which part of your monthly spend is going to ingredients below a researched dose.
It works in US Daily Values with NASEM upper levels, or UK NRV with EVM levels, switchable in the app, because those two sets genuinely disagree and most apps only carry one.
The free tier is three label scans and one full stack analysis, with no account and no card. That is enough to see what it does to your own shelf and decide.
It reports the arithmetic and names the source of every figure. It doesn't tell you what to take.
If you are in the UK
SuppCo is not available there, and the field looks completely different. We wrote that one up separately, with the same kind of live numbers, in best supplement scanner apps in the UK.
Which kind of supplement app do you actually need
"Supplement app" covers three different jobs, and the store listings blur them. Deciding which one you want first saves installing two of the wrong kind.
A scanner reads a label. Point it at a supplement facts panel and it reports what is in the bottle and how each amount compares to what research uses. That is the category every app above belongs to, and it answers "is this product worth buying".
A tracker records what you took and when. No camera, just a checklist and a history. It answers "am I actually taking this", which is where most supplement money quietly goes to waste.
A reminder is the thinnest of the three, a notification at 8am. Most trackers include one and your phone's alarm covers most of it.
A tracker will never tell you your zinc is underdosed. A scanner will not stop you forgetting to take it. Decide which problem you have.
Verdict is a scanner first, with intake tracking attached, because the question it was built for is about a whole stack rather than one bottle. If you only want a daily tick box, a supplements app without a camera will serve you better.
How to pick
Honestly, by which question you have.
If you want to know whether a brand is trustworthy, a catalogue app with a big database and a trust score answers that well, and SuppCo answers it best on the numbers above.
If you want to know what your combination adds up to, no single-product scanner can tell you, because the answer is not printed on any one label.
And if you scan something and get nothing back, that is the catalogue question, not a broken app.
