What our clients say

We have localized over 1,500 projects and produced 1,000+ videos. Let's make something special for you too!


Nitro is extremely helpful when it comes to localisation for us. Allowing for quick turnaround, with great support, the results are of high quality. It's a core part of our process.

Kasedo Games

Christian Woolford, Producer


We used to work with freelance translators via a crowdsourcing platform, but the process was lengthy and complicated. With Nitro it’s easy for us to translate texts for our games into multiple languages simultaneously: we just copy the text, specify the languages needed, and receive our translated texts within 24 hours!


Ekin Usumi, Community manager


Alex Nichiporchik explains the decision to localize their game into Chinese: "China is a huge market. We have already recouped the localization costs. Our first sales event after completion of the localization project demonstrated that China is now one of our top markets for 'Punch Club.' Over the past two weeks we've had just as many sales in China as in the US.


Alex Nichiporchik, CEO


Nitro has been a fantastic service to use for my localization needs. The accuracy of the translations and the speed that I get them back is very convenient for my day-to-day work loads. Their support staff has also been very attentive to my experience and makes sure they do everything they can to make my user experience easier.

Ziggurat Interactive

Emilio Clancy, Associate Producer


We have been working with Alconost for about six months on the Samedi Manor project. Quick technical support and maintenance. The most suitable for all requirements, including urgency, localization service. We receive positive feedback from users from the target countries about the localization.

Black Caviar Games

Lyudmila Kozlovskaya, ASO Manager


It works great for translating small texts into many languages ​​at once. Instead of running around and searching for translators, you can just copy and paste the text, and in like half an hour, you get an email notifying you that the text has already been translated into 3 languages. It's pretty much a perfect self-service.

Duck Rockets

Alexey Dmitriev, CEO


We tried working with freelance translators, but it was time-consuming and far from efficient. We switched to Nitro completely, because with Nitro the translations are ready quickly — as soon as in 2 hours — and all the questions regarding game-specific details are conveniently handled with a manager in the chat.

Full HP Ltd.

Lidia Musakaeva, ASO Specialist


During our many years of working with Alconost our experience localizing game content has been exceptionally enjoyable and beneficial. I’d like to emphasize how smoothly the entire team works together. Alconost’s managers are positive, focused people who always listen to our preferences.


Alexander Kolychev, producer


I contacted Alconost when I needed to translate a game into ten different languages. The translation was completed very quickly and in a format that was convenient for me. I’d also like to mention their managers, who are very friendly and always willing to help. They were very kind and helpful, and I enjoyed interacting with them. All in all, my experience working with Alconost was extremely positive.

RUD present

Rudolf Lacinov, Games developer


In the year that we've been working with Alconost we've had an exceptionally positive experience: their work has been fast, high-quality, and in strict observance of the deadlines agreed on. We are looking forward to a fruitful partnership going forward.

Vizor Games

Valentin Romashko, Project Manager


The localization of payment interfaces is one of the most important steps for a company entering a new market. Thanks to Alconost's assistance, the company was able to adapt its Xsolla payment interfaces for hundreds of different countries in the shortest possible time. The higher the quality of the translation, the faster users will be able to learn how to use the interface and the more purchases they will make. You cannot underestimate the importance of quality localization.

Is localizing a game worthwhile?

The cost of translation depends on:

  • the volume of text to be localized (number of characters including spaces). Only the text to be translated is billed, exclusive of markup and code.
  • the number of hours spent on localization testing (LQA). We strongly recommend LQA, as it ensures the highest possible quality of localization.

Translation cost varies by language. This is due to different standards of living in the native-speaking translators' countries of residence. You can calculate the approximate cost of localization for your app or game on your own using our price list.

But it's best to submit a pre-order and attach your files. That way we can calculate the cost ourselves, charging for nothing but the text.

Continuous localization workflow

Using online platforms lets us structure the game localization process in such a way that when an app is released it is always fully translated — continuously, at any time. This works approximately as follows:

  1. The developer adds a new string to the game's resources.
  2. The updated resource file is automatically sent to the localization platform (via API or using a command-line utility). The translator immediately sees the new text.
  3. The translator translates the new string.
  4. Before releasing the latest build, the updated translations are collected from the platform - again, automatically.
  5. In this way each time the game is compiled all localizations are 100% ready, and the update is never delayed.

Self-serve platform Nitro for localizing game texts, ads, and updates

If your game contains only a little text or if you plan to localize it yourself, take a look at Nitro - a professional online translation service. You can place an order with Nitro in just a few clicks, any time that's convenient, without involving a manager.

Nitro's service is designed for swift translation of text into multiple languages simultaneously. It is especially convenient for translating sales descriptions for stores, "What's new" texts, and updated strings into several languages at once.

To ensure uniformity of all the translated texts, use a glossary. With Nitro you can create a new glossary or upload an existing one, which is particularly convenient if you are ordering a translation of updates for a previously localized project. To upload your glossary to Nitro, write to us via online chat.

Game localization quality assurance (game localization testing services)

Quality assurance testing takes place as follows:

Once a localized build has been compiled, the translator or native-speaking tester plays the game for the required amount of time and takes screenshots of problem areas (things left untranslated or lines that are too long, improper coding, incorrect text orientation, contextual errors, etc.).

In the developer's project management system (Jira, Trello, Asana) the tester creates a record of all the defects detected and makes the necessary changes to the string resources, either independently or with the help of the developer.

The cost of localization testing is calculated based on the tester's hourly rate and the time required for testing.

We are able to test games created for the following platforms: iOS, Android, Windows, MacOS, Xbox, PlayStation (PS3, PS4), and Nintendo (3DS).

Translation memory and glossary

A translation memory is a database that stores both the original and the translation of each segment of text. A translation memory can automatically translate repeated words, phrases, and sentences.

Translation memory lets you:

  • streamline translation teamwork;
  • ensure uniformity of terms throughout the text;
  • improve translation quality;
  • replace a translator during a project;
  • save on translating repeated phrases.

This means that if your game is available on both iOS and Android, for example, and 90% of the string resources are identical, the matching strings are translated automatically and cost you nothing.

A glossary is a special dictionary with explanations, translations, and sample uses of terms encountered in the text. This kind of dictionary can be imported to an automated translation program, so as to speed up the work and ensure that specialized terms are translated uniformly throughout the text or in all files for translation.

Having a glossary lets you involve multiple translators in the project and switch them out during the course of the work.

If your game does not have a glossary yet, we can help compile one.

Online platforms for game localization management

The cloud platform CrowdIn lets you manage localization projects in real time. You can:

  • upload string resources in any format (.resx, .po, .strings, etc.), either manually or via API;
  • appoint translators and editors;
  • track the translation or editing process of your project online;
  • communicate with translators and editors in the comments as questions arise;
  • create glossaries;
  • organize translation memory creation and usage;
  • export string resources after translation.

Learn more about Alconost's experience working with CrowdIn.

We also work on other localization platforms, such as GitLocalize, Phrase, Lokalise, Memsource, Memoq, Smartcat, Webtranslateit, Transifex, OneSky, POEditor, Trados, and many more.

What languages to localize your game into first

We've analyzed the number of internet users who speak each language, online sales volumes overall, and Google Play revenue in particular for each region. This resulted in the following top 5 languages for localization:

  • English — USA, Great Britain, Canada, Australia;
  • Chinese — China (simplified Chinese) and Taiwan (traditional Chinese);
  • Japanese — Japan;
  • French — France, Canada, Belgium;
  • German — Germany and Belgium.

Extra services

In addition to localizing mobile apps, we can also help you:

  • evaluate your game's name from a native-speaker's perspective;
  • create a trailer for your app's page on the App Store or Google Play;
  • put together a series of short videos in different languages for posting on advertising networks;
  • provide voice-over for your game with the help of professional, native-speaking voice talent;
  • select fonts for new languages.

What languages do you translate into?

We translate into more than 100 languages, including the most popular (English, Chinese, Japanese, German, French, Spanish), and rarer ones, and even dialects. To get a precise estimate of the localization cost, please, request a quote.

We can find a translator in almost any language that the client needs, depending on his product and goals. Sometimes localization into niche languages can offer better prospects than localization into mainstream languages.

In case some rare language is not on the list, we can help with searching and recruiting linguists.

How can you automate my localization workflow?

We have plenty of automation options to streamline the workflow for the localization of your game.

Firstly, if you want to quickly localize a glowing review, test an ad for a foreign market, or adapt ASO for your international players, you can use our human translation platform Nitro that delivers translations by native-speaking linguists within 24 hours. Nitro has a free translation API that's compatible with all programming languages (Python, JavaScript, Java, PHP, etc.) and platforms (iOS, Android, etc.). Once you set up the Nitro API, you can upload and retrieve translations within your own project!

If you’re looking to automate the workflow for the localization of your game on a larger scale, we work with professional translation APIs and Translation Management Systems (TMSs) that help reduce back-and-forth and keep the lines of communication clear and simple. We also work with other translation and localization APIs of your choice on request.
