Four taps. One honest answer.

No typing, no guessing which number goes with which product. You tell the app exactly what to read — it does the math.

1

Tap A's price

Point the camera at the shelf and tap the first product's price.

2

Tap A's size

Tap its size — grams, millilitres, or a count like "12 pack."

3

Tap B's price & size

Do the same for the second product. Four taps, that's it.

4

Get the verdict

See the winner, the price per unit, and what to consider.

An answer that's honest about close calls

Better Value won't oversell a tiny difference. The verdict is graded against the real gap in unit price.

Under 0.5% apart

Basically identical

So close it doesn't matter — buy whichever you prefer.

0.5%–2% apart

Slightly better value

A real but small edge. Worth a nudge, not a sprint.

More than 2% apart

Better value

A clear winner. The app shows exactly how much you save per unit.

Built to advise, not just calculate

Better Value reads like an assistant — it separates the math from what actually matters.

📏

Real unit math

Normalizes everything to grams, millilitres, or each — so 750 mL vs 1.2 L is a fair fight.

Things to consider

A short, plain-language list of what might change your mind — not just a number.

Never guesses

If it can't read a label confidently, it asks you to verify rather than making something up.

Everything happens on your iPhone. There's no account to create, no server to send data to, and the camera image never leaves your device.
