Guidance conveyer

I gave this 5⭐️s,I almost gave it 4 only due to the fact that sometimes I encounter words with no 'learners' definition. But I can not be that picky or critical being that this is a free app filled with copious amounts of information and reliability. That being said... I am extremely satisfied with this app!! I can not spell to save my life and have been saved countless times when referencing this app. Also, while working on my latest degree (3rd)(Bsn), I faced a plethora ( just used it to look up this spelling) of papers and discussions I had to write. I referenced this app many times to decide if my word choice fit my sentence or represented my thought(s) appropriately. I really can't complain about the things I don't get from it, being that it is free, I'd rather boast about what it does give me and express my gratitude for all the possibilities I was able to uncover because of it! So thank you!
Yours truly,
Excellent spelleroid (some one who is excellent at spelling... But isn't!)

Apps changed a lot

I used to use this for mpoints cause I love learning new words and had it linked to my reading/ writing app abd I used it ALL the time, thus learning abd getting ALOT of points from a great USEFUL app that I actually used in every day life, which I still do however this app has changed TONS and they just want you to buy more apps and upgrade this one which is "redic" for a dictionary app! And it's more about blogs and slide shows etc which I have not really looked at a lot since I use this as it is, or was, supposed to be, a dictionary, and I got points for it, which was a GREAT GREAT plus! But now I can't even find the mpoints link it pops up at times saying I got a few points though, so I guess that's good, just wish there was still a link!!!!! ALL other apps have the link (a little box to click on or something similar) AND wish this app was easier to use, more simple like it used to be... Anyway good dictionary, best one other than the one linked to my kindle, I guess ...

I am not a good speller and I speak Russian so having the words explained really helps.

I love how it's easy to use. Very easy to understand. The best part is the M points you get to earn when you use the app if you have other apps that have M points it gathers them from all other apps so you can get the points all together. I'm a medical assistant and the medical part of this app helps so much it translates the words for you even some words like LB - pounds. So it's so cool. When I was in collage out teacher told us the get this app and use it because it worked wonder and yes it did it saved lots of my home work assignments. But I truly advise you not to pay for the other app it takes away some things so I have two apps on mine and I use the free one more not as much the one I bought. Take care. Dictionary & Thesaurus
