Currency Converter Plus

Review by eFreeware

Currency Converter Plus is a paid Android app from Designer Calculators, sold for $2.99 with no ads and no in-app purchases. It does one job: turning an amount in one currency into its equivalent in others, with up to 15 currencies visible at the same time. The pitch is narrow, and that is exactly the appeal.

Most converters try to be a dashboard, with charts, historical data and rate lists. This one keeps the main screen for the currencies you care about and lets the numbers update while you type. For a traveler standing in a shop abroad, that is the whole task: type the price, see what it costs in money you understand.

Because it is a one-time purchase, the experience is meant to stay out of the way. The app is framed around the moment you need a price translated, not around a feature list.

Converting while you type

The core interaction is immediate: as soon as you start entering digits, the conversion happens across the currencies you have chosen to display. For repeated small calculations, that rhythm matters more than any chart.

You decide which currencies occupy the main screen, up to a maximum of 15. That ceiling is generous enough for a multi-country trip, a household dealing with a couple of foreign bills, or someone tracking a handful of rates at once. The list of currencies is searchable, so finding the one you want does not mean scrolling through everything.

The design is described as suited to tablets, which suggests the layout scales beyond a phone. I would expect the wide-screen version to be the more comfortable one for anyone comparing many currencies side by side.

Doing arithmetic with the numbers

A built-in calculator handles the case where the amount you need is not a single price. You do the math in the app, and the result is converted into all of the displayed currencies automatically. That saves the awkward step of working out a total elsewhere and then re-entering it into a converter.

This is the feature that makes the app useful beyond simple price checks. Splitting a bill, adding up several purchases, or applying a discount all become one operation instead of two. The conversion follows the calculation rather than the other way around.

Preferences let you adjust smaller details of how the app behaves. The intent is clear: users are expected to tune the app to their own habits rather than accept a fixed layout.

Rates on the road and without a connection

Exchange rates are cached, so conversions keep working when there is no connection. The developer frames this around roaming charges, and the point stands: you can check prices in a foreign shop without paying for data or hunting for Wi-Fi.

When you do have a connection, the app updates rates online. Sources include the European central bank, additional feeds and RSS, and you can also enter a custom currency manually. If a currency is missing, you add its code, run an update, and the app downloads the name and current rate; from then on it is included in automatic updates.

That combination covers the two situations that matter: a reliable set of major rates that refresh themselves, and a way to add something obscure without waiting for the developer to include it.

Getting it set up

Setup is mostly about choosing your currencies. You pick the ones you want on the main screen, up to 15, and the app converts between them. If something you need is absent from the list, you type its code as a new currency and run an update so the name and rate are fetched.

After that first update, the developer says the added currency is kept current automatically along with the rest. The app is bought once and the rates are the only thing that needs refreshing.

The app has been on Google Play since March 2010 and was last updated in August 2026, with the most recent release covering minor fixes and a request for user feedback. That long run suggests the app is still tended to.

Where a paid, single-purpose converter fits

This app suits people who convert currencies often enough that friction becomes annoying: frequent travelers, remote workers paid in another currency, shoppers buying from foreign stores, or anyone handling expenses across borders. Paying once is a straightforward trade for that group.

It also fits users who value a screen they configure themselves. Fifteen slots is enough to keep the currencies you actually use in view and ignore the rest. The search filter keeps the longer list manageable when you need to add or swap one.

The narrower fit is someone who wants analysis rather than conversion. There are no charts or historical trends here, by the developer's own framing, and the app is built around the immediate question of what something costs.

With a 5.0 average from 972 ratings and more than 10,000 installs, the audience is not enormous, but it is clearly a settled one.

A focused buy for frequent converters

Currency Converter Plus is worth considering if you want a converter that opens straight into your own set of currencies, updates as you type, does quick arithmetic and keeps working without a connection. The ability to add a custom currency code means an unusual rate is not a dead end.

I would point it at travelers, cross-border shoppers and anyone whose work involves regular currency math. If you want charts or historical data, this app's design choices point elsewhere, and that is a fair thing to know before spending $2.99.

For the specific job it was built for, the feature set lines up well: 15 currencies on one screen, instant conversion, a calculator that converts its own result, cached rates for offline use and a choice of update sources. That is a coherent package rather than a pile of extras.
