PONS Dictionary Library is a program that gives you access to word translations, definitions, and pronunciations. This utility might come in handy if you're studying a foreign language or you're simply requiring assistance when translating a piece of text.
You don't need much computer experience in order to use this program as it comes with a user-friendly interface. The words are listed on the left side of the screen and you can use the built-in search tool to find the word definition you need.
Furthermore, you can mark your favorite terms, check the irregular verbs list, and listen to word pronunciations if needed.
Unfortunately, not all content is free of charge. Many words definitions are locked and the only way to get rid of the limitation is by making an in-app purchase. Also, you need to pay in order to have access to additional dictionaries.
Nowadays, when you can find almost any information you need regarding translations on the web. So, I can't find a reason why you should pay for a dictionary app when you can find anything you need online.
