I was too busy with work to get started, but recently I listened to the lectures and created an app in just about 8 days. I haven't done Android yet since I don't plan to release it, but for iOS, I've already submitted it for App Store review. The deployment section was so kind and detailed, which was great. I'm still waiting for the review, but I hope it passes. As you mentioned, I'm planning to try releasing as many apps as possible. Thank you for creating such a good lecture. I recommend it. Highly recommend!
