How we picked

Every app on this page is ranked by a quality score that combines its Google Play star rating with how many people have actually reviewed it — so widely-trusted, highly-rated apps come first, and a perfect score from a handful of users can't game the order. We then sanity-check each pick against the theme of the collection and surface the key facts (price, size, ads, age rating) up front so you can decide at a glance.
