Much better!

I decided to give this app another go because I missed being able to switch between thesaurus and dictionary easily.
Ian glad to report that the new updates since I have last used his app have much improved the experience. Thank you for listening and removing the annoying features, and improving on existing, beneficial ones. Rock!

Old review:
The recent updates are terrible. The app is super slow, you no longer have the option of going back to previous words, and to top it all off, the adds purposefully get in the way of where you are about to tap. There are buttons along the bottom of the app screen that are moved up by adds. They take just long enough to load that, by the time you have finished typing, instead of tapping the synonym or origins button, you tap the advertisement which opens up a web browser. This is not effective advertising! Not only that, but you have lost a customer. Goodbye.

App Forces Reinstall for those who had the Offline Dictionary before the Update

I among other people had this app installed along with the offline dictionary functionality. Then somehow, it started crashing. Had no choice but to delete it and reinstall. Then I find out that now I have to pay to get the offline dictionary again.
Honestly, I cannot remember if I already paid for this since it's been years since I started using this app. But if this was done on purpose, I don't know what to think.
It seems I'm not the only one who has this problem from reading the reviews. While $3 is nothing, I will not purchase it just in case the issue reoccurs and the app starts crashing again.
Despite this, it's still a good app so I can't give this review one star.

Can't live without!

The upgrade has great new features like the dictionary and thesaurus toggle on main screen. Personally I love the word of the day image grid! Best way to memorize new words and the previous ones I liked. This app really helps me in expanding my vocabulary. This in turn helps in communicating with articulate personnel. Thank you! Keep up the good work! Dictionary & Thesaurus
