## What is Boomerang by Illuminated Bits?

Boomerang leverages Google Translate to provide translations between over 100 languages. Translating isn’t always perfect though, and can lead to embarrassment. To help avoid this, Boomerang translates from one language to another and then back again so that you can verify the translation is what you intended. If needed, you can also try adjusting your statement to get a result closer to what you want to say.

Boomerang is helpful for translating and checking text when communicating to a friend who speaks another language. It’s also handy when travelling, or can be used just for fun to get some purely comedic results.

Note: As Boomerang uses machine translations available from Google Translate, accuracy cannot always be guaranteed. Additionally, while back-translation hasn’t proven to be a 100% reliable method for checking translations, it’s still a useful method.

The app is free to use with a limit of 5-free translations per day. An optional premium subscription removes ads, unlocks unlimited translations and pronunciation for supported languages. You can choose from a monthly or annual subscription. See the details below.

### 1/5 — 400% renewal price increase! $1.99 to $9.99

*2021-03-07, version 2.0.2*

The 400% renewal price increase is outrageously high! Went from  $1.99 to $9.99 now.  This app was okay for me but not perfect.  I did not mind the $1.99 renewal fee.  Between this app and Google Translate (Free App) I was able to use both together to get a translation. I could not use the voice/audio feature because the language I am translating (Filipino/Tagalog) is not supported.  For the amount of money they want now ($9.99 annually) I will “NOT” renew and add my name to there growing list of unsubscribers.  There are other apps I can use with Google Translate and achieve the same results.  If the developers of this app ever decide to lower the price of this app to a realistic price increase then I might reconsider.  400% is not a fair realistic price increase in my opinion. The 1 star giving by me is a fair rate because of how much they increased the annual renewal fee amount.

### 1/5 — Shallow and terrible

*2020-07-04, version 2.0.2*

Terrible app. Imagine offering a free service with a great premise: you get to double-check your translations, but here’s the catch: NOW YOU ONLY GET 5 FREE ONES A DAY. YOU HAVE TO SUBSCRIBE?! What a terrible decision, app developers. You have lost all my respect and I have deleted this app. I will be spreading the word as well. Having to pay for this service, not to mention monthly, when it was, for one, previously free, and secondly isn’t anything special. Get rid of your ego and greed and actually be a good developer. Disgusting and shallow.

### 5/5 — Love this app

*2020-06-24, version 2.0.2*

This app is very well made. I use it all the time to check translations while emailing other countries or anytime I need a quick translation.

### 1/5 — Total App Fail!

*2019-03-06, version 1.08*

It doesn’t work at all. You’ll see English➡️Spanish, you can’t change either language because the app crashes. Even if you try to use it to translate English to Spanish, the app still crashes. It’s supposed to have 100 (I think that many) languages. It’s last update was a year ago. It was listed in the App Store in March 2019 with other translation apps. Did no one check before promoting this piece of junk??? Really disappointing!

### 3/5 — usable but could be improved

*2019-02-27, version 1.08*

Pros:
Cool service.  I wish i didn't need a separate app to have this service (Google translate web has it but the app doesn't) but alas.

Cons:
・App doesn't remember any of the languages you frequently pick, and the list of languages is looooong.  This is ameliorated somewhat by having a search box in language selection, but I'd rather it just remember.

Criticisms:
・The settings menu holds no settings.
・If you visit the "settings" menu, you are greeted by a lovely attempt at guilt tripping for money.

### 5/5 — C’est parfait !

*2019-02-05, version 1.08*

i use this application to translate french and anybody that has used other translators knows that french translators are hard to find. this application is perfect. i have used this app to translate professionally and informally. this translator has never given me an incorrect translation. it even corrects your phrase and helps translate. shows you what you said, what it translates to in french and then it translate what it translates to in french. definitely recommend this to anyone that can not find a proper translator. i use this app at least once a day.

### 5/5 — Seems really good.

*2019-01-15, version 1.08*

The translations seem very good. As someone learning the language, it would be very helpful if you also provided pinyin like Google Translates does.

### 5/5 — Translating the translation

*2019-01-13, version 1.08*

Very good concept and more powerful than a normal one direction translator.

### 1/5 — Needs a lot of improvement

*2018-01-08, version 1.08*

I was looking for an alternative to google translate. So far looks like no one can beat them. Why would I want to use this app if I have a limited amount of characters I can input, and adds pop up everywhere? If anyone wants o be google then try making an app without adds that’s capable of translating an entire paragraph. Inoltre, non penso sia appropriato che uno sviluppatore di app insulti un consumatore perché si è lamentato del suo prodotto. Apparentemente non è per tutti. Tuttavia, non ho alcun uso e cose migliori da fare con il mio tempo che passare tutto il giorno a passare da un'applicazione all'altra per tradurre la stessa frase 50 milioni di volte.

**Developer response:** Thanks for your feedback. Our goal isn't to beat Google. In fact, the translations we provide are powered by Google. Our goal is to provide a convenient way to double-check a Google translation. We do have character limits, but 95% of our customers don't come within 20% of that limit.

### 5/5 — So clever in its elegant simplicity

*2017-12-27, version 1.08*

When you need to use Google translate, but don’t totally trust it, you need this. Boomerang automates a series of steps I used to do manually all the time. Translate something and then translate it back to English and  so you can confirm that the translation didn’t get mangled in the round trip and is reliable. Highly recommend this very useful tool if you look up translations even just once in a while.

## Frequently asked questions about Boomerang by Illuminated Bits

### What does Boomerang do?

Boomerang is a utility app that leverages Google Translate to help you verify the accuracy of translations. It works by translating your text from one language to another, and then translating it back to the original language. This back-translation process allows you to see if the meaning has been preserved.

### How does Boomerang ensure translation accuracy?

Boomerang uses a back-translation method. You input your text, it translates it to a target language, and then translates that result back to your original language. This allows you to compare the original and the back-translated text to ensure the intended meaning is conveyed. You can also adjust your original statement to refine the translation.

### Is Boomerang free to use?

The app offers a free tier with a limit of 5 translations per day. For unlimited translations, ad removal, and pronunciation features, there is an optional premium subscription available on a monthly or annual basis.

### What languages does Boomerang support?

Boomerang supports translations between over 100 languages, powered by Google Translate. The premium subscription also unlocks pronunciation for supported languages.

### When would I use Boomerang?

Boomerang is useful for communicating with friends who speak other languages, for travelers needing to confirm messages, or even for fun to explore comedic translation results. It's designed to help avoid misunderstandings caused by imperfect machine translations.
