I personally tried the mobile version of this wallet and so far I haven't had any problems - I even used the swap option several times and everything went well. I also had a question for their customer service, which can be contacted directly from the wallet, and I received a response within 1 hour (maybe even less), which is definitely one of the good things.

Another handy thing is the ability to purchase virtual cards and gif cards directly from the app, and availability of course depends on the country you are in. All in all, I have no complaints about this app (mobile version) so far.
