The app has many usability issues. But let's focus on the most urgent. Blocker: one of the fill the blanks via speech, keeps showing me a popup "sorry this isn't an option". Although I tried all options (even the obviously wrong once). Very annoying: most exercises are made of multiple parts. If you yoi don't finish them all, no progress is saved for that exercise and yoi have to start it over next time.

The idea of the app is great. But it doesn't work well. For example, when i record my voice for vocabulary words even if it checks it as done when i get back to the menu it shows me that i still have vocabulary activity not finished. I have to do it 5 times minimum for it to finally register it. It is so annoying and it happens to other activities too! Please fix this!

Can't believe this is a paid service! The app doesn't fit the screen size properly. Sometimes you can't see the answer you need or you only see part of it. Also, the grading is ridiculous. Many times it's OK to use or not use a subject in Spanish. Not according to this app! If you're supposed to be learning verbs, but add an extra space to your sentence - WRONG! It's too inflexible and frustrating, which is the enemy of language learning. My job pays for this. If it's your own money don't get it
