Risks and disadvantages of translator apps

Translator apps are practical whenever you’re in a hurry and offer valuable help in conversations with locals, especially when traveling. However, they do not even come close to the performance of a professional translator or interpreter.

It is advisable to employ a professional interpreter, especially in direct dealings with international customers or business partners, e.g. during negotiations and at events. In this way, you can make sure that you and your business partners understand everything exactly so that no costly misunderstandings occur.

At EHLION we offer you interpreters for all languages. Find out more about the various interpreter services and languages which we offer here.

Anyone who uses an app to translate technical terms or requires flawless translations of precise technical terminology or legally binding formulations also should be careful and should preferably hire a professional to perform the corresponding translation.

Data input also involves certain risks since, once entered, your information remains stored on the provider’s server and hardly can be removed. Your data are thus located in the public sphere.

Comparison of translator apps

Finding the translator app that is right for you is not so easy. There is a wide range to choose from and the many different functions of the available apps make it hard to choose. Popular allrounders such as the Microsoft Translator app, Google Translate or PROMT convince with a great diversity of languages, a wide range of functions and constant updates and improvements.

The Microsoft Translator is popular especially due to its many technical features. The iTranslator even makes it possible to select between various dialects. A special app with a well-functioning voice output such as Waygo or Pleco is above all practical for travelers. The translator apps are recommendable for English-German translations.

Such an app cannot replace a professional translator or protect users against translation errors. However, the app is very practical when traveling and will provide you with “language first aid” whenever your own language skills prove inadequate.
