It's an interesting app, although it hasn't got an update in a while (almost a year now). There are still some issues on the UX/UI spectrum, and inside the app is not that fancy (and at times clunky) but it gets the job done. What I don't like is that I have tried again and again to make payments for the monthly and yearly options, but I'm unable to, and support hasn't been as fast on the responses. This is the main reason I got to type this down.
If they were to maintain the app updated (and had speedy responses to me in that area) I'd give it a 4.5-4.7 stars, because they solve a need and the ongoing updates help them gain ground in the 5-star vicinity.
