Redbox Instant (iOS|Android) lets you manage your rentals from your smartphone or tablet and offers instant movie streaming, but the streaming catalog is not on par with other services like Netflix.
To get started, you'll need to be a subscriber or you'll need to create an account with Redbox using your credit card for access (just like Netflix); the good news is you get a one-month free trial to see if you want to stay on board.
Once you're set up, the home screen for the Redbox Instant app is laid out a lot like Netflix's, with thumbnails of movie posters sorted by category. Across the bottom of the screen are buttons to navigate to each section. You can browse movies by using a drop-down menu in the upper left to switch between genres and Redbox-curated collections. You can look at the My Redbox section, where you'll see your viewing history, movies you've bookmarked to watch later, and previous purchases. A locations button pinpoints all the Redbox locations in your area. There's also an account button where you can see how many rentals you have left for the month and a preferences section to restrict content if your child will be using the device.
