Robust dictionary and thesaurus with a suite of helpful resources
Overall, this is a great app for its ease of use and simple navigation between dictionary and thesaurus. There are a lot of blog-style articles with quick and entertaining info related to words, grammar and language. One thing I feel would be a helpful improvement would be a dedicated section under a searched word that displays all forms of that word. The app does display “Other words from ______” but a lot of the time it only shows the word with different prefixes or suffixes, or slightly different words that contain the original word. I’m constantly searching a word just to check all the different forms of a specific word and it’s just not available a lot of the time. Also, even after disabling WOTD and SOTD notifications in the app, I still get daily notifications for both.
