“Nitro was a pleasant find for me”
A simple and at the same time very powerful service for localizing your content. Simple registration, transparent price, a huge number of languages, and fast order fulfillment.
“This is my favorite service for translation into several languages at once.”
I translate phrases of my android app into five different languages. It is a small size, and some new terms appear from time to time. It would be challenging to look for freelancers for such goals, so the choice fell on this service. And I like it.
“I had fast and good results for my localization project.”
We have worked with the company several times. Each time we returned to them for a new localization of our product. We have done French, Spanish, and Portuguese localization and always had great results.
“Good service for good money for your all translation needs”
It doesn't matter If you need to translate either couple of words via Nitro or a localization file Alconost will do that for you promptly. I do a fintech platform and use the solution to localize my product for global customers to speak to them in the same language.
“Translation of in-game texts and metadata for the Google Play & App Store for Action RPG and Simulation games.”
We translated in-game texts and descriptions for the app stores in US, UK, DE, FR, SP, IT, PT (BR). Translations were done quickly, edits were made, communication with translators was fast.
“I searched among many services and settled on this as it works with all my 30+ languages.”
If you need to translate quickly and efficiently a small number of words or large volumes of text, then this is probably the best solution. Besides, everyone knows about them. Excellent support in your native language excellent prices. You can translate even one word for a couple of cents, which will not take more than a couple of hours. This is what I need.
“Fast translation service in multiple languages with an intutive interface and responsive support”
I like the way I can get translations in a variety of languages. Whether it is a short sentence or something longer, I am sure I will get text within 24 hours. But what is more, it comes much faster. This does not create bottlenecks in my workflow. The support team responds promptly. I had an isssue with which I appoached them in a live chat. It took no more than 1 minute to respond and that issue was fixed. Overall, I am glad with the service and continue working with them.
“Fast and professional translation service with great support and constant improvements”
As a mobile app developer which publishes worldwide, we require professional translations for many languages. We think that Alconost probably is the best solution for our needs - it has everything: speed, quality, low price. They also constantly add new languages and improve Nitro by adding new useful features, for example, you can upload screenshot with text, so that translator would have more context. We highly recommend this service for everyone who needs fast and professional translations.
“I have translated several mobile apps using this service into multiple languages”
I have translated several mobile apps using this service into multiple languages. It was both long sentences and short phrases. I also added screenshots so that the translator could understand the context.
“Project managers were a pleasure to deal with. Communication was good overall and they finished the work quickly and asked good questions.”
Alconost Inc. provided translations for a game project. They were flexible and willing to go the extra mile to not only provide what I was asking for but also check the previous translations. I would use them again on future projects.
“Tailored approach to the customers need when it comes to translation services.”
We started working with Alconost from January 2022. The communication was good from the start & they really thought along with us. The communication goes really well via a linked slack channel & they are very flexible when it comes to how payment is done, but also which translation tool is used. They support all the 9 languages we need & deliver usually within 2 business days.
“Excellent professionals”
I have been working with Alconost since 2015. During this time they translated hundreds of thousands of characters for me and helped launch dozens of projects. For me, this is not just a cool service, but also great people. During this time, several managers have changed: Stas, Dmitry, Nadezhda, Yana, Evgenia ... Only the quality manager Vladimir and the soulful attitude towards me remained unchanged. Each of them did a little more than he was obliged to do: laughed at my jokes, helped to compose texts, filed appeals to the arbitration system, sent me photos of their pets, congratulated me on the holidays... And of course... Solved any problems with the translation of my texts into dozens of languages. RTL? Hieroglyphs? Rare file format? No comments? No difference. The text will be translated with high quality and on time. Do the translators have any questions for me? The manager has already translated them into my language and sent them by mail. Thank you for being. I would gladly recommend Alconost to anyone who needs a quality translation. Good luck!
