This is the most trustworthy wallet of all I have ever tried for Monero. Well, I got not only XMR in my portfolio, but I've always preferred mono wallets to multi-currency ones. And because of it, there's a huge collection of wallets on my phone.
This particular wallet captured my attention with its intuitive user interface presented on the promo screenshots. I really enjoyed the simplicity of it.
Then, having installed it, I was able to realize all the security measures to protect my account. Most of all I'm fond of a finger-print log in as well as the required 2FA.
I also like the idea of a cold storage: it makes me think that my Monero are reliably stored.
