Simple, to the point

I came across this app from TikTok. After the first use, I immediately deleted my Dictionary app. This app is so much more approachable, simplistic and still provides a plethora of synonyms, antonyms and the definition itself; love it! As it progress, I would love to see a flash card setting, where you can randomize words you’ve looked up to help in remembering the definition for the long term. Love the app! Keep up the great work!

Thank you for the suggestion! A flashcard setting is on the horizon for later this summer! I believe flashcards are a great way for people to learn vocabulary and would be an excellent complement to the app. I can't wait to build and share it with you. Thank you for leaving a review!

Fun and useful!

On my first use of the Lekses Vocabulary and Dictionary App, I’m finding that it goes straight to the point of the definition and proper use of a word. What I think stands out most is the ability to find words that rhyme with one quick touch! It’s also extremely easy to find synonyms, antonyms, and options for using a word differently in a sentence structure. This thesaurus aspect will be a treasure in my references. I’m going to enjoy this app!

Developer Response ,

Woohoo! Glad you are finding the app so helpful! You hit the nail on the head for what we designed Lekses to do.
