## What is Converter (unit conversions)?

"A very nice, no-frills tool—the best of the lot." —Macworld Magazine (4 mice)

The easiest unit converter in the App Store is back and better than ever!

Converter helps you with the mess of units you encounter in your everyday life. Convert from feet to yards to meters to miles with only a few taps. Converter handles 76 measurement units of eight common types, including length, weight, temperature, speed, data, volume (including common cooking units like teaspoons), area, and time. And you can subscribe to our daily exchange rates to add support for 161 currencies.*

Converter is designed for easy, casual use, with big, beautiful displays that are usable in all light conditions and at arm's length. And it includes a four-function calculator for those times when you have twelve three-pound widgets and you need the kilogram equivalent.

* An optional Latest Exchange Rates subscription unlocks the currency converter and provides daily exchange rate updates for one year. Subscriptions are auto-renewing and are charged to your iTunes account. Your first year will be charged as soon as you subscribe; subsequent years will be charged up to 24 hours before the previous period expires. You can cancel at any time through the "Manage Subscriptions" button in Converter's About screen or your iTunes account's settings. Please cancel at least 24 hours before renewal to avoid being charged. For terms of use, see https://www.architechies.com/apps/converter/ios/help/terms.

### 5/5 — Converter

*2026-02-06, version 4.3*

The most excellent software

### 1/5 — Currency out of date

*2025-12-17, version 4.3*

The currency function won’t update to current rates

### 2/5 — Doesn't Stay Current

*2025-03-05, version 4.3*

It complains about not have been updated and the won't do it

### 1/5 — No longer supported

*2024-07-04, version 4.3*

It’s seems I have been paying for the last few years for the Exchange Rate conversion within this App and there servers have been down for 566 days or more. Very disappointed with this! Before this I used the App frequently and found it great which is why I paid yearly for the exchange rate updates service

### 5/5 — Barry

*2024-04-17, version 4.3*

Simple and easy to use and always at hand.

### 3/5 — Currency rates not updated in 2336 days

*2024-01-29, version 4.3*

How come ?

### 5/5 — Great / Simple

*2024-01-27, version 4.3*

Clean , simple no nonsense.  
Just wish you could stay on one screen to scroll through conversion options while viewing results on the fly.  For example: since there is so much space (read uncluttered- I like) it would be nice to spin through say Inch/Foot/Yard etc. while staying on results screen.   If it had this it would be a perfect app.

### 5/5 — Converter

*2023-12-02, version 4.3*

One of the best converters I seen by far 😁

### 2/5 — Currency rates have not been updated

*2023-11-21, version 4.3*

I continue to get an error that currency rates have not been updated in almost a year.  Something wrong with the server.  No technical support.  Subscription is worthless.  Otherwise I like how the app functions.  But not worth paying for.

### 4/5 — Review

*2023-09-23, version 4.3*

I really enjoy this app! I am a chef and this helps me so much while at work and home!
However, in the last few months the app won’t work correctly. I have to open and shut the app over and over again in order for it to work.

### 4.2 — 2017-10-03

Converter 4.2 includes fixes and improvements to make Converter more pleasant to use.

• Bug fixes:
  • Customers who have switched from 24-hour time to 12-hour time will now be able to use their currency subscriptions. We’re very sorry about this bug!

### 4.1.2 — 2017-09-25

WHAT'S NEW IN CONVERTER 4.1:

We’re consolidating our three versions of Converter down to one, so this version is based on Converter Neue’s more modern design. Changes from Converter Neue include:

• Converter is now free. The currency section unlocks with a ridiculously cheap in-app subscription.
• We’ve added over 100 new currencies, including Bitcoin.
• Converter for iPad isn’t a separate app anymore—it’s part of Converter.
• We now support iOS 11, larger iPhone screens, and landscape mode.
• We’ve tweaked the design a bit to make certain things more readable.

We've also fixed a few bugs:

• Entering Celsius temperatures actually works.
• Fractions are now correctly formatted.
• We are using a new, more reliable source of exchange rates—if a currency was showing “(Rate unavailable)” before, it will probably work fine in this version.

We hope you like the new version of Converter, and we hope the exchange rate subscription will let us spend a lot more time improving it!
