Whoever rated this higher is a shill. DON'T believe them
What ...frightening about it, is it's similarity to a search app(the EXACT same layout, i.e., nothing), and if you see that app (and it's reviews), you'll see itmgot nothing but terrible reviews.
So; how to explain the huge discrepancy in the reviews?
Very simple; don't trust ANYthing which is given nothing but top marks, no flaws - 'perfect'.
There's no such thing as 'perfect', and even for something I've reviewed, and thought was great, I'd never give it 5-stars.
There's always room for improvement, so, when you've got on the one hand some of the best known, best liked apps constantly trying to rethink their app to better it, here comes this bottom feeder - something no one's heard of, and which doesn't work, yet people say it's the best thing ever.
Those are liars. Those are the people who'd sell a used car, and tell you it's not had one prior owner, an elderly women, who only used it to go to church once a week.
You can take these bobble-heads at face value, and try it yourselves, or you can not waste your time, and do something - anything - which is better for your time.
Excellent app
