This is the first Monero application I managed to clearly understand from just the first glance. It has a very intuitive UI in comparison to any other wallets: the UI is very clear and readable, with no any extra features or rubbish. However, it also has some useful features like a build-in exchange which helps you to convert your XMR to some other cryptocurrency or vice versa. Amazing! I also really liked the color scheme.
Been using this application for a few weeks, so can't honestly say that it works without any issues: two weeks is not the point of judging. Yet, no lags seen. Hope, this fact would be helpful :)
What else? The fees here are quite low and what is the best fact about it, there's no fee between Freewallet users. It already makes me wanna stay.
