I just started creating apps on Blockstack, I would like to request your feedback on my apps, they are still on MVP phase.

StackFolio
The first one is StackFolio, an encrypted crypto portfolio tracker, it allows you to track your crypto portfolio without worrying about being tracked, your data is encrypted to safeguard your sensitive information. We use Blockstack's encrypted storage when handling your data.

Memocards

The second one is Memocards, it is a simple flashcards application that allow you to create flashcards and study it. It is simple but effective for studying to exams. We also did a stats dashboard where you can follow your progress.
