About this app

Unit Converter: convert any measurement, currency or size in one tap.

IN SHORT

A fast, offline unit converter that turns any measurement, currency or clothing size into the answer you need — with live exchange rates and a built-in calculator. If you can use a calculator, you can use this.

WHO IT'S FOR

Cooks, contractors, DIY-ers, students, travelers and anyone who needs a quick, precise conversion. Also handy for engineers, nurses and online shoppers comparing international sizes.

WHAT YOU GET

• 18+ categories in one place — weight, length, temperature, volume, speed, area, time, data, energy and more.

• Live currency conversion — real-time exchange rates, updated automatically.

• A real calculator built in — type an expression and convert the result instantly.

• Works offline — every unit (except live rates) converts with no connection.…

4 measured · 4 not assessed

“Not assessed” means we could not measure it. It is never a zero and never a pass.

Five-star share of ratings
65–79% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 3.0.30 · 2026-10-28
What's new: • New Baker's Percentage calculator: flour is 100%, every ingredient shows its percentage and weight, editable both ways, in grams or ounces. Start from 8 recipes: bread, baguette, sourdough, Neapolitan and New York pizza, focaccia, brioche and sandwich bread. • Search now finds calculators by their name. • Fewer interruptions: rating requests now appear much less often. • Privacy: you can now change your consent choices from Settings, where applicable. • Fixes: screw sizes, Beaufort wind scale, size tables and inch fractions (2.5 now shows as 2 1/2).

Purchases the store lists

 What this app sells

From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.

This list is cut off. Apple shows at most 10 in-app purchases, and this app is at the limit — so it very likely sells more than we can see.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
