I think you'll have a better experience in the website than the app. In my opinion, I rather to buy the complete plan for 3 months if you don't want to lead with buying credits. it includes a DET course (5 stars), DET exercises practicing, IA interactive speaking, Mock Test. Buying Arno DET worthy, I consider better than Teacher Luke's at DET. I give a 4 stars to the app since the Arno's website is more complete than the app.

a lot of stupid mistakes in grammar. It is obviously that this app is designed and created by AI with no human quality assurance. Totally useless

Hello! I'm sorry that you didn't have a positive experience with Arno. Yes, we do use AI for our instant feedback on writing and speaking questions, but DET experts on our team spend a lot time checking the quality of the feedback. If you've paid for a subscription and are not satisfied, we will gladly give you a refund: support@goarno.io.

This app is heavily expensive. Each small feedback costs credits. There is no premium version, you have to purchase credits over and over again in order to maintain proper feedback. Without credits you even don't get the information if my answer was right or wrong. Ridiculous! Besides there are a huge amount of bugs as well.
