Conversion: Unit Converter downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About Conversion: Unit Converter
Type a number. Read the answer. That is the entire app.
Conversion has been on the App Store since 2012. Version 4 is a complete rebuild — modern, quick, and still refreshingly free of clutter.
BOTH UNITS, ALWAYS IN VIEW
The two units face each other in the middle of the screen, right where you left them last time. Flick either one to change it, or tap an amount to turn the conversion around. Nothing to drill into.
TWELVE CATEGORIES, 96 UNITS
Length · Area · Volume · Weight · Temperature · Speed · Pressure · Power · Energy · Time · Computing — and Currency, with more than 160 world currencies.
LIVE EXCHANGE RATES
Rates refresh on their own and are stored on your device, so conversions still work on a plane or underground. When a rate is out of date the app says so, rather than quietly handing you an old number.
YOUR LANGUAGE, YOUR NUMBERS
33 languages. Unit names, decimal separators and numbering systems all follow your region — so a comma lands where a comma belongs, and Arabic and Devanagari numerals are drawn properly.
BUILT FOR iOS 26
Liquid Glass, a colour for every category, fluid animation, haptics, and Dark Mode throughout.
ACCESSIBLE FROM THE START
Every control is labelled for VoiceOver. Text scales to the largest accessibility sizes. Reduce Motion is respected. A hardware keyboard drives the whole app.
NOTHING COLLECTED
No account, no ads, no analytics, no tracking. The app makes one kind of network request — for published exchange rates — and it carries nothing about you.
Pay once. No subscription.
