Remember the bad old days of ordering food? You needed takeout menus, knowledge of the terrain ("will they even deliver out here?"), cash, and faith that the person jotting down your order got it right. Seamless takes care of all that, even letting you pay via credit card from your Android. The only drawback? It's not available in every city (or even every state), though it has expanded its range dramatically since it was first included on this list. Android App

There's both a light and dark theme and tons of layout content customization options to try out, even if you don't opt for the paid version. Better yet, there are no ads in either version or RIF and its overall performance is extremely quick. New Droid Apps

Shows such as Black Mirror, Stranger Things, and The Crown (the most expensive TV show ever made) are often the conversation topics of the day.
