None of the 'crypto-portfolio apps' that I know of are scams? You just help people track and manage their coin related data and not the actual coins right? Never been a fan of portfolio apps but that is the most common niche in this section. We get such apps launched here every week.
Yes, you are right! crypto portfolio apps can only read your portfolio, it can not be a scam
there are plenty of the crypto apps out there, you are right again, but we believed that it can be something, we wanted to benefit the crypto community: )
No, but they could contain malware that steals coins from your wallet on your devices.
OP, is it possible to get your app audited by Google play?
The fact that you've been allowed to the Apple app store is a pretty good sign that it does not contain malware.
Getting verified by Google play would also be a big plus.
When are you going to add it to the play store, instead of just offering the app on your own website?
