Yes it is nice to go on it.
I have an older phone but it works from time to time ;-) I know also it is in development and i see that they did a lot of improvements in last 2 months.

I hope they will have time to get it better with favorites and things that can ease up the daily user reading and savings.
Eh... try it and see it. I don't think you'll regret it.
Watch also to put your posting key, not the main one. Just like in all external apps, to be safe from the start.
Use your main key or pass only when you need to do transactions.
