Great designs! very high quality work, I appreciate all the efforts you have put into creating this!

I would suggest two improvements: 1-You need to include Admin portal and dashboard to keep track of students’ progress, names, and show Realtime data charts about all these variants. Another developer has already done that you can find it here to get an idea: https://codecanyon.net/item/study-flutter-courses-admin-client-template/49870769# So far they only have one sale more than you, but I am sure this will increase the sales for your product.

2- Definitely include the images/graphics! I am sure they will help increase your sales. If you don't own the copyrights, replace them with other images which you can create using AI. You made all that effort to create the app/product so don't let that only thing hold your clients back from purchasing your product.

To be honest, I am thinking of going with the other product I just shared its link just because of the Admin and Dashboard features. I am not in a rush though, so if you can and want to make these changes, please let me know. I would love to go with your product instead! Cheers,
