Best app ever for readers-Edit- don't buy

I have had this app for almost a year, in that time I have used it on more then one occasion when I come across a word I don't see very often, and the medical upgrade has helped with that tremendously. One of the best apps I have ever paid for.
Edit: with the new update I am just upset over the fact that I have spent quite some money on this app just for it to now be "free" with all the upgrades. What about all the people that have poured money into it?
Edit2: I tried to email the company yet there is no information on how to do that so I will leave it here as well as the Facebook page, my app now also crashes. So after all the money I spent in the past to get everything (including the translation they will be stopping) I can't even keep the app open longer the 10 second. The longer I have this app the more I regret it. It use to be my favorite.

Dictionary Ease of Usefulness

I love this dictionary/thesaurus because it fits right in my purse, pocket, or backpack. Which is extremely helpful for me as I am in a wheelchair. It is just the right size to have with me whether I am doing school work, or reading for pleasure. It's extremely complete for my needs, and it takes just minutes to find the word I am looking for and I can get right back to what I was doing, without having to carry a 5 pound dictionary with me every place I go. Definitely a 5 star 2 thumbs up ap.

Losing value; no feedback capability

The original program I purchased allowed me to translate. As of 30 April 2017 that function is now gone.

Also, I was looking up the word "hoplophobia" and discovered it unavailable. I think it looked it up with an Internet search and found the definition. I assumed that I would now present this to the writers of this app and let them in to her the word so that it would be available. It appears there is no easy functionality to make a recommendation for a word. Dictionary & Thesaurus Premium
