Customer Reviews


Constant badgering to upgrade and rate them. I like to download the free versions and get to know them before I decide to buy. When I am hassled every time I turn on the app it's a put off and not only do I not buy but I then delete because the idea of a free version is to give you limited access to the app with a taster of its usefulness not to be hassled.

Good for learner, can be better without push ads

The learner function is very helpful when it comes to understanding the context of each word; however, the push ads sometimes diminish the user experience.

Could be better

I would give this app a 5* rating where it not for the annoying prompts to upgrade. Dictionary & Thesaurus
