At a rough guess 99.9% of people here either haven't made a decision where to go yet, or are already committed to staying. And since your 'ideal app' depends on your personal preferences and needs, it's likely to be unhelpful to listen to anyone who thinks its the best thing since sliced bread because all they do is use it for shared shopping lists. A google search got me a random collection of reviews and comments, which is (I think) a lot more than you're likely to get here. I don't use it, and although it seems pretty and (probably) harmless, I won't be trying it out anytime soon.
