Google Translate remains, by far, the most used translation application in the world in 2024. Its download milestones on the Play Store surpass those of all its direct competitors. However, this ranking by installations masks a more nuanced reality: the boundary between standalone applications and integrated translation features is quickly fading.
Massive installations versus active usage: what the Play Store milestones don’t reveal
The Google Play and App Store listings display download milestones for each translation application. Google Translate dominates this metric, followed by Microsoft Translator, DeepL, and Reverso. However, these raw figures can be misleading.

A download does not equate to regular usage. Reports from mobile analysts published between 2023 and 2024 indicate a growing divergence between total installations and actual usage time for utility applications like translators. The frequency of use is declining in favor of features integrated directly into messaging apps or browsers.
Platforms like Data.ai or Sensor Tower publish rankings by DAU (daily active users) and MAU (monthly active users), category by category. These data, rarely cited in mainstream comparisons, are the only ones that measure actual usage. Most articles simply state that an application is “popular” without utilizing these indicators. To identify the best translator according to Au Top, one must cross-reference installations, retention, and frequency of opening.

Translation integrated into operating systems: the invisible competition of Google Translate
Since 2023, Apple, Google, and Samsung have integrated translation engines directly into their systems. Apple Translate works natively in Safari, iMessage, and iOS settings. Google itself offers translation in Chrome, in the Messages app, and in the Gboard keyboard, without the user needing to open Google Translate.
Samsung has deployed its real-time translation feature during phone calls on the Galaxy S24 range. Microsoft integrates Translator into Edge, Outlook, and Teams.
This native integration poses a measurement problem. A user translating text via the Chrome address bar does not appear in any Google Translate statistics as an application. The underlying engine is the same, but the usage escapes the store counters.
We observe that this trend mechanically reduces the number of sessions attributed to standalone applications, without the overall volume of translations decreasing. On the contrary, it is increasing.
Google Translate, DeepL, Microsoft Translator: comparative technical positioning
The three dominant applications do not target the same usage. Their architecture and functionalities diverge on structural points.
- Google Translate covers more languages than any other consumer tool. Its voice translation, text recognition via camera, and offline mode make it the most versatile tool for travelers or casual users.
- DeepL prioritizes translation quality over a smaller number of languages. Its neural engine produces results perceived as more natural for European language pairs. DeepL Pro offers enterprise-oriented features: custom glossaries, API integration, translation of entire documents with preserved formatting.
- Microsoft Translator integrates into the Office 365 and Azure ecosystem. Its strength lies in multi-device conversational translation and API access for developers. Real-time voice translation in Teams positions it in the professional segment.
Reverso, often cited in French-speaking comparisons, occupies a different niche. Its main asset remains the contextual dictionary and usage examples in context, particularly useful for language learning rather than for raw translation.
Output quality and post-editing
Neural machine translation (NMT) remains the technical foundation of these applications. Language models (LLM) are beginning to play a complementary role, particularly at DeepL and Google, to refine the register and textual coherence on longer passages.
In professional contexts, none of these applications eliminate the need for human post-editing for published content. Machine translation with post-editing (MTPE) remains the standard for companies that require publishable quality.
Criteria for choosing a translation application in 2024
The choice depends on the use case, not on a universal ranking. We recommend prioritizing three technical criteria before comparing interfaces.
- The language coverage: Google Translate dominates if you work with rare languages or unusual pairs. DeepL and Microsoft cover major business languages.
- Integration ecosystem: a user embedded in Office 365 will save time with Microsoft Translator. A developer looking for a quality translation API will turn to DeepL Pro or Google Cloud Translation.
- Offline mode: Google Translate offers downloadable language packs. DeepL only works online. For travel use without a connection, this point is decisive.
Voice and camera translation
Camera translation (OCR + NMT) and real-time voice translation have become expected features. Google Translate remains the most advanced in these two areas, with character recognition that works on non-Latin alphabets in real-world conditions.
Microsoft Translator offers a multi-participant conversational translation that has no direct equivalent at Google or DeepL. This feature, designed for multilingual meetings, connects multiple devices in the same translation session.
Google Translate maintains its leading position by user volume and the versatility of its features. DeepL is rapidly advancing in the qualitative segment. The real shift of 2024 is occurring elsewhere: translation is migrating from applications to system layers, making the very notion of a standalone application less and less relevant for measuring the actual usage of machine translation.
