I was really excited to get LearnSpanishwithEasyTen and loved the trial so much that I downloaded the full premium version. Unfortunately I was a little disappointed...
I paid to have two languages but cannot learn two languages at the same time which is quite frustrating given that I paid for the full version. You have to switch between languages and can only have one per day. Additionally, as a near fluent speaker, I find the lack of words annoying. There are many words I want to learn but cannot. There is not even a way to add them yourself. Also for French, there are no articles which makes telling the gender of words difficult at times. The pronunciation for many words is the wrong word, so the tests are frustrating. Also crashes occasionally, especially when switching languages.
I like having the words for your (only one!) language selected for the day show up as often as you want on the lock screen though, that's neat.
UPDATE:
Garbage app. The pausing of new words does not work and the selection is very poor and limited. You cannot simply go back and look at your words from other days before being forcefed 10 new words for the day. Horrible if you want to focus on certain words and ignore their useless word choice system. Do not buy.
Also devs are not responsive to my questions or complaints.
