5 stars: Wonderful app for practising pronunciation...... Initially you can practise with a free version and after going through all the lessons in the free version you can buy a premium pack. It's highly reasonable; considering it gives you conversation practice and pronunciation feedback at the same time. You can practise a word or sentence until you get above 75% score. Advanced learners should get 90+ score. Go for it!
4 stars: The app seems to work fine and does what it promises. However, the monetization feels really bad and it's not cheap. Elsa is constantly throwing you to other lessons (that you don't need) and locking content that was previously available. With a free account, I don't see anyone moving away from the very basic anytime soon. Not to mention the reminder for the paid version all the time, everywhere. What a shame.

It has a delay since you press until you start talking and especially in exercises that you're requested to talk a phrase after another it's a big nuance!
3 stars: Maybe it's good for beginners. If you have some English background and want to improve it, don't bother. After 10 minutes, I was on advanced level, then never got anything 100% again. Always some inaccuracies. I asked my native speaking friends to try. She wasn't any better than...
