Why would you need to a £40 per subscription to a dictionary? This is a total rip-off and could easily have had a one-time payment with paid for updates, but they went down "we hope you forget to cancel your subscription" model. Please do not support this behaviour and look for alternatives.

Hello. 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.

Incredibly intrusive ads. Subscription model. Since the internet is there for free, I don't see why you'd use this app. I would be happy with a one time purchase as I would like the ability to save words and I'm trying to get better at looking up words I don't understand. I wanted a dictionary app to not distract me from reading my book, but ironically I've ended up leaving this review after a poor user experience.

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

I needed a thesaurus, so I downloaded this. after ten minutes turning off all the cookies and privacy invading "legitimate" interests from third parties, I was greeted with a screen inviting me to enter my personal and payment details to access a 3-day free trial of the service, which I would need to manually cancel on order to not pay £19.99 annually. I immediately deleted this app, and have bought a second hand copy of the Oxford English thesaurus for under £3, and I urge you to do the same!
