What is assetdash – crypto portfolio tracker for iPhone & Android?

I'm curious to learn more about Assetdash, a cryptocurrency portfolio tracker for iOS and Android devices. Could you elaborate on its key features and how it differs from other similar apps? Specifically, I'm interested in knowing if it offers real-time price updates, the ability to track multiple cryptocurrencies in one portfolio, and if it has a user-friendly interface. Furthermore, I'd like to know if it supports security features such as encryption and multi-factor authentication. Finally, is Assetdash available globally, or are there any region-specific restrictions?
