Need some new features

Great app! I use it a lot for computer programming, hardware components, etc. questions! I really love it!
I’d like some added features on it though, specifically maybe the Word of the Day. That’d be cool! And also maybe add a video that talks about the searched word for the customer.
Also, I’m learning iOS app development right now and I’d really like to contact you to get some help and ideas for other app ideas I have.
Thank you!

This app is amazing I have yet to encounter a word this app does not have! It explains the word precisely and if it has multiple meanings then it has those as well! I am grateful to use this while studying for my A+ and soon other exams. I hope this app continues to update its words!

Much more comprehensive than I expected. I thought it would be only basic terms with basic definitions. Not the case. Tons and tons of terms and the definitions are concise at the top but also include lots of details afterwards. Very well done.
