Stacks - App Review

Stacks is a currency converter but has the clean lines of something that has been well thought out.

iOS 7 seems to be catching some developers out... some are not updating their offerings, some are, and a few (such as the guys at WapleStuff) are creating Apps around the new iOS.

Now for the ACIDS test:

The basic screen looks like a calculator, except that it doesn't have any function keys (!) but has two lines of currencies (just flick them left or right to change them), a 'chase myself' wheel, a bookmark, yellow back arrow and a 'go to' marker.

It might sound unusual but, a few seconds with the App and you will be hooked.

Simply enter your source currency on one line and the value in your target currency is automatically displayed on the line above.

The 'chase myself' wheel serves to inverse the source and target currencies, while keeping the value you entered (handy if you had it the wrong way round).

The yellow back arrow deletes the last entered character, making corrections fairly painless.

The bookmark icon allows you to save, and name, a particular item. This is great if you are comparing similar items in various currencies, as you can then easily go back and find the best deal.

The 'go to' marker opens up Calzy (there's a review of this App here), a great calculator, and already has the value you were using displayed.

Then come the gestural actions:

Swipe down - updates the exchange rate
Swipe up - opens settings (including sound)
Double tap - opens bookmark list
Rotate to see chart - very interesting to plot the rise and fall of currencies

This is an, almost free, App at $1.

If you don't carry out currency conversions in your head, use this App. If, on the other hand, you are a whizz at exchange rates, gift this to people who keep pestering you with "so how much is that in...".

It works.

The App is self-contained and does not share information... unless you have Calzy, in which case it forwards a value to the calculator (hardly a security risk).

ACIDS Test Rating:

For travellers and international on-line shoppers.
