Marius Royal, Content and Community Manager


During the rapid growth phase of any startup, you appreciate anything that saves you time. And with a growing international user base, translation quality affects the way people feel about the reliability of your company.
With Alconost + Crowdin we loved the way translation is guaranteed to be accurate and context-appropriate. Above all, we valued having the same team working with us over time - it’s important when you have a lot of industry-specific words. They can speed your work up the same way they did ours.

App In the Air

Timur Akhmetgareev, Co-Founder


Given the volumes we need to translate weekly and the number of languages we localize our website and apps into, Alconost offered us the best solution in terms of flexibility, pricing, and quality among the translations agencies we were considering. The quality of the translations is quite high with the proofreading service that Alconost provides. Our Alconost manager is one of the nicest people I've ever met. They always pay attention and try to meet our translations needs in the best way possible. They were especially helpful during our transition to Lokalise for app localization, so we were able to build and maintain a consistent and reliable localization process.

Movavi Software Limited

Natalia Bogorad, Head of Editorial


We have been working with Alconost team for many years and never had an issue and with the time the quality of localization services only increased.

Matt Kryvashein, CMO


Our experience with Nitro has been nothing but positive. Your service has been a true life-saver! Translations into 32 languages are oftentimes ready in just one business day, and we can quickly add the option to the app without a release. We also appreciate that we can submit even a single word for translation.


Alexander Lozitsky, CEO and co-founder


Nitro is our favorite go-to service when we need to quickly translate various interfaces into multiple languages ​​at the same time. It has a really cool feature where you can provide the translator with comments and screenshots, which is so important for obtaining an accurate translation.

Your one-stop application localization service

App localization platforms and continuous localization

Using online platforms, you can arrange the localization process so that your app is always fully localized at the time of each release, regardless of your release cycle or even the time of day. This works approximately as follows:

  1. The programmer adds a string to the file containing the string resources and publishes the changes, for example, to Git.
  2. The file updated by the programmer is sent to the localization platform using a special command-line utility. The translator sees the new string immediately.
  3. The translator translates the new string.
  4. The updated file containing the string resources is fetched from the platform using the same command-line utility before the next build of the project is compiled.

Thus, when you are ready to release your app or game, all localizations will be 100% ready and will not delay your release.

For continuous localization projects we usually recommend the cloud-based translation platform Crowdin, which allows localization projects to be managed in real time.

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

Professional translation and project management

With Alconost, your localization project will be handled by a dedicated project manager. Your project manager is your “single point of contact,” who will help you resolve any and all your questions regarding the project. The project manager:

  • Studies your material and the unique features of the text in depth
  • Works out the price, taking repetitions into consideration
  • Selects a team of translators and editors with the requisite specializations
  • Oversees deadlines
  • Supervises the quality, formatting and consistency of the completed translations
  • Maintains the glossary and translation memory
  • Organizes linguistic testing
  • Prepares all required accompanying documentation (agreement, invoice, PO)
  • Is available practically 24/7 to answer any of your questions

광범위한 분야의 전문성을 갖춘 원어민 전문 번역사 약 700명이 Alconost 팀에 소속되어 있습니다. Alconost는 프로젝트에 항상 전담 번역사 1명 이상을 배정하여, 지속적으로 해당 번역사와 작업하기 위해 노력합니다. 주기적으로 업데이트되는 대규모 프로젝트나 일관된 용어 사용이 필요한 작업을 수행할 경우 혹은 특정 번역사의 스타일이 마음에 드는 경우 전담 번역사 제도는 매우 유용합니다. 또한 어떤 사유로든 전담 번역사가 바뀔 경우 새로 프로젝트를 맡게 된 번역사에게 용어집과 번역 메모리를 제공하여 향후 업데이트 시 용어와 스타일의 일관성을 보장합니다.

Mobile app localization testing

After the localized version of the app has been compiled, a localization specialist tests the build on the relevant local version of the OS. During linguistic testing, the tester takes screenshots of problem areas (untranslated text, strings that go off screen, wrong encoding or text direction, wrong context) and works with the developer to make changes to the resource files. Our linguistic testing service is available to you even if you have already translated your app yourself or through an outside provider. Learn more or order localization testing for your mobile app.

Translation of short in-app texts, app store descriptions, and updates

If you need to translate a few short texts, or if you are planning to manage the translation on your own, consider Nitro — our professional online translation service.

What can be translated with Nitro:

  • Short in-app texts and updates
  • App store descriptions
  • Materials and website texts

You can place an order with Nitro in just a few clicks, without involving a manager. You can request swift translation of texts into several foreign languages simultaneously, within 2-24 hours. To ensure consistency, you can create a new glossary or upload an existing one to Nitro.

Creation of videos for apps, localization of video and audio content

App localization cost and pricing

The cost of localization depends on several factors

  • Amount of text to be translated (number of characters including spaces)
  • Languages
  • Cost of subscribing to the localization platform
  • Cost of proofreading (if any)
  • Cost of localization testing (if any)

What languages should I translate into first?

We’ve analyzed the number of native speakers who are Internet users by native language, the total volume of online sales, and Google Play revenue by region. This resulted in the following top 10 languages for localization:

  • English – United States, United Kingdom, Canada, and Australia
  • Chinese — China and Taiwan (Simplified and Traditional Chinese)
  • Japanese — Japan
  • French — France, Canada, and Belgium
  • German — Germany and Belgium
  • Russian — Russia
  • Korean — South Korea
  • Spanish — Spain, Mexico, and Argentina
  • Portuguese — Brazil

Ultimately, the choice of languages depends on your product type and business objectives. For instance, localization into niche languages can sometimes offer better marketing prospects than mainstream locales. So always keep your product in mind.

Alconost는 가장 인기 있는 언어(영어, 중국어, 일본어, 독일어, 프랑스어, 스페인어) 및 소수 언어, 방언을 비롯한 100개 이상의 언어로 번역 서비스를 제공합니다. To get a precise estimate of the localization cost, please, request a quote.

고객사의 제품과 목표에 따라 고객사에서 요구하는 모든 언어의 번역사를 찾을 수 있습니다. 사용자가 적은 언어로의 현지화 작업이 주류 언어로의 현지화보다 더 밝은 전망을 제공하는 경우도 있습니다.

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