OptimallyKnow what’s really in your food.
Scan any barcode for a 0–100 score built from the ingredient list. Every rating is deterministic and cited — the same ingredient gets the same verdict, every time. No AI guesswork, no brand money.
App StorePaid subscription. Price and trial shown before you pay.
Other scanners guess. Optimally shows its work.
Most food scanners send your product to an AI that will happily give you a different answer if you ask twice. Optimally runs a fixed set of published rules — so the score means something, and you can audit it.
Deterministic
Same ingredient, same rating — every time, on every phone. Fixed rules, not a model that contradicts itself between scans.
Cited
Every flag traces to a published paper you can open and read. Where the evidence is thin, the app says so instead of pretending.
Private
No account, no email, no ads. Your scans, profile and lists stay on your device — and we never sell your data.
Built for the ten seconds you have in the aisle.
You’re standing in front of forty products and the front of every box is marketing. Optimally reads the back instead.
- Scan the barcode. No barcode, or it won’t read? Photograph the ingredients — the text is processed on your device.
- Read the verdict. A score out of 100, the flags behind it, and every key ingredient rated with a one-line reason.
- Find something better. See cleaner alternatives in the same category and build a shopping list from them.
Four screens, no dashboard theatre.
Real screenshots from the app. The products shown are Optimally’s own demo items, so nothing here is a brand we were paid to flatter.
Scan or search
Point at a barcode, photograph a label, or type a product name. Recent scans keep their scores.
Read the verdict
A 0–100 score, the flags that drove it, and every key ingredient rated with a reason.
Check our work
Each rule links the paper behind it, and shows how many of your own scans it touched.
See the pattern
What share of your scans are ultra-processed, and whether your Clean Score is moving.
Two bars in the same aisle. Not the same food.
Both are sold as protein. Optimally doesn’t care what the front of the pack calls it — it reads the ingredient list and the degree of processing.
Three ingredients you can name
A short list of recognisable foods, minimally processed. Optimally has very little to flag, and the score reflects that.
A long list, mostly not food
Refined syrups, industrial oils and additives that only exist to survive a warehouse. Optimally names each one and links the evidence.
Every rule has a paper behind it.
Optimally’s Research tab is not a blog. Each article states the claim, links the evidence, and shows the exact rule it drives — read straight out of the scoring engine, so the explanation can never drift from what actually scored your food.
- Peer-reviewed studies, plus EFSA and IARC assessments where they exist.
- Honest about weak evidence — animal-only findings are labelled as such.
- Shows how many of your scans each rule actually touched.
Optimally is a paid app. That’s the whole business model.
There is no free tier and no ad-supported version. Subscribers are the only people Optimally answers to — which is exactly why no brand can buy a better score.
