Take care, a phone has a lot of vulnerabilities when compared to best practices. Use with burnable amounts. But ya, it's an awesome app. I've been used to using mymonero.com for such purposes, and this much easier and more convenient. Add a hardware wallet for topping up, you are safe and versatile. SoonTM
Actually an Android phone is probably mores secure that a Windows PC because it runs all apps in a virtual machine. Of course though there's always the risk of your phone being stolen and went through if you don't have a password or gave the password to the person who decided to go through your phone.Well that goes without saying. Windows is self described as malware, if you read the fine print. Nowhere will you find Windows included in ''best practices'
But who knows what that app you downloaded to put monkey lips on pictures of your family? you gave it file access. Maybe it will just grab any wallet . dat files etc. too.
Who can realy call any phone safe?
