Has to be the worst dictionary app ever conceived. The free version is so ridiculously useless, I couldn't possibly evaluate whether it is worth a purchase. immediately upon opening it, before even selecting which of the dictionaries to use, the screen is filled with an ad that has no visible way to close it. After five minutes of struggling to even access the app itself, I un-installed.

Hello Brendan . The free version includes full dictionary access with ads. Premium removes ads and unlocks offline use, audio pronunciations, thesaurus, examples, and more. We’re always working to improve and appreciate your input.

Oxford dictionary $3 a month sub review I have bought Oxford dictionaries in the past and I don't understand why I can't purchase this app, I can lease it for $3.50 a month. I have got enough monthly payments coming out of my checking account already, and at this rate it looks like the only smartphone apps I can use for free are Waze, Google maps, and various shopping apps.

This app is unusable unless you sign up for their subscription. I refuse to pay a subscription for a dictionary, that's absolutely ridiculous. I want a one-time payment for very basic access to a complete digital dictionary and thesaurus, just like if I were to purchase hard copies at a bookstore. Edit: Since I can't respond to the response - your product is unusable with ads. That implies that the paid version is also poorly coded with a lot of bugs. I'm just going to buy a real thesaurus.

Hello Grace. To maintain a completely free-to-use app while offering advanced paid functionalities, we rely on two support methods: ads and the cost of the paid version. If ads are bothersome, please consider upgrading to Premium for an ad-free experience and access to the full feature set.
