Help for Converter for iOS

When I purchase or restore the currency subscription, Converter says “Please purchase the software application first.” What gives?

This usually happens because you originally downloaded Converter with a different App Store account from the one you're using now. Delete Converter and reinstall it from the App Store, and it should work fine.

Why can't I unlock the currency converter?

If the currency subscription screen says "Not Available", or you buy the subscription and nothing happens, these are bugs that have been fixed in recent Converter updates. Please launch the App Store app and check the Updates tab to see if there's an update you should install.

If this still happens in Converter 4.2 or later, or you're experiencing some other problem, please contact Converter Support so we can help you with it!

How do I use Converter?

Using Converter is basically a three-step process:

  1. Select the conversion category from the bar at the bottom of the screen.

  2. Tap one of the blue unit buttons, then select a unit from the list that appears. Then do the same with the other unit.

  3. Tap one of the blue numbers, then enter the amount of that unit into the calculator. Tap the "Done" button to finish. The app will now show the amounts.

For example, if you want to convert 98.6° Fahrenheit to Celsius:

  1. Select the Temperature category at the bottom of the screen.

  2. Tap the top unit button and select Degrees Fahrenheit. Tap the bottom unit button and select Degrees Celsius.

  3. Tap the Fahrenheit screen and enter 9, 8, decimal point, and 6, then hit "Done" in the bottom right corner.

Converter will tell you that 98.6° Fahrenheit is 37° Celsius.

Converter doesn't have a unit or category I want to convert. Can you add it?

We do add units from time to time, but we don't include every unit or category requested. One of our biggest concerns with Converter is that it be kept simple and small enough that people can easily use it, and as you can imagine, twelve screens of units in each category would be a bit of a handful! We don't attempt to include every function—just the ones we think most users will need.

Nevertheless, we do sometimes forget to include common units, especially ones that aren't common in the United States, so let us know if you want us to add something. We keep a request list as well so we can see what people are asking for. Just email us with your request and we'll consider it!

What's a marketing gigabyte?

Computers typically consider a gigabyte to be 1,073,741,824 bytes (that's 1024 × 1024 × 1024). However, marketers often advertise hard drive capacities with a gigabyte equal to 1,000,000,000 bytes (that's 1000 × 1000 × 1000), so they can put bigger numbers on the box. This is technically the size of a gigabyte (the computer size is technically called a gibibyte instead), but almost nobody actually uses it that way unless they're selling a hard drive.

Therefore, Converter tries to match common usage by setting a "Gigabyte" equal to the measurement computers usually use, while "Gigabyte (Marketing)" is the measurement marketers use. The same thing is done for terabytes, which suffer from the same ambiguity.

Converter's currency rates won't update, even though my device is connected to the Internet. What should I do?

This is probably happening because your device's access to our exchange rate feed is being blocked somehow. See if you can visit this website (www.architechies.com) on your device. If not, or if our site shows an error, that's probably the problem. Once that's cleared up, the currency converter will be able to update. If you see something wrong but you're not sure how to fix it, take a screenshot (hold down the Home button and press the Lock button; the screen will flash and a picture of what's on it will be added to your camera roll) and send me an email; I'll try to help you with it.

I see you include Bitcoin in the currency converter. What about my favorite altcoin?

Our exchange rate provider plans to add Ethereum and Litecoin before the end of 2017, and when it does, we'll put them in Converter. We'll keep an eye on other altcoins too, but we're pretty conservative about our currency choices.

Do I need separate currency subscriptions for my iPhone and iPad?

No! A single subscription covers all of the devices using your App Store account.

If one of them doesn't know you're subscribed, tap the "Restore" button on the currency subscription screen. If that doesn't work, contact us and we'll help you out.

What happened to Converter for iPad and Converter Neue?

We've retired these variants and brought the best of them into Converter, which now sports Converter Neue's modern interface and Converter for iPad's support for the iPad. This will help us keep Converter up to date in the future, and also means you don't have to pay twice for iPhone and iPad.

(Besides, the old versions would not have run on iOS 11 anyway.)

Didn't the currency converter used to be free?

Yes. We've since switched to a more reliable source of currency data that offers over 100 more currencies, but our new source is more expensive and we need subscription revenue to pay for it. We've set it about as low as we can—99¢ US per year—to keep from locking anyone out.

If you purchased a paid Converter app or in-app purchase on or after June 1, 2017, please contact us and we'll give you your first year free.
