App of the week:

The newest film in the “S t a r Wa r s ” f r a n c h i s e , “Rogue One,” is out in theaters. Several excellent scie n c e - f i c t i o n - t h e med T V shows are on the air. And there are more sci-fi and fantasy films expected soon.

That means it’s a great time to be a science-fantasy and science-fiction fan. And in a galaxy right here today, a lot of that content is designed for the supercomputer smartphone in your pocket, so you can take your love for the genres anywhere you go.

For s t a r t e r s , t here a re the Lego Star Wars game apps. These have always been excellent — cleverly put together and containing many amusing moments that tie in to the movies.

My recommendation is Lego Star Wars: The Yoda Chronicles, based on everyone’s favorite small, green Jedi knight. As with the other Lego games, this is a 3-D puzzle-solving game that involves the occasional bit of combat. Your characters roam around an environment that fits into the “Star Wars” sto- ries, picking up Lego pieces, smashing objects and using powers to assemble piles of Lego pieces into useful tools that can help get to the next level. The graphics are excellent and the gameplay is satisfying. The app is free for iOS and Android.

For more “Rogue One” content, turn to Disney ’s official Star Wars app.

It has been updated with content from the new movie, including videos and news. My favorite part of the app is the soundboard section where you tap on the screen and are rewarded with sam- ples of speech from your favorite characters or iconic St ar Wars sound effec ts. The app is free on iOS and Android.

Blastr, which is free on iOS and Android, is a different kind of science-fiction app, designed to bring together news about sci-fi matters from across the web. The home page contains many thumbnail images that entice you to read more, along with a few introductory words. Tapping on a story preview takes you to the full article to read inside the Blastr app, or click through to read it on the original website.

This year was also important for fans of another big science-fiction franchise: “Star Trek,” which this year celebrated its 50th anniversary. One of my favorite apps cel- ebrating “Star Trek” is the official TrekMoji app. This $2 iOS and Android download contains many cartoon-drawing-st yle emojis featuring characters and quotes from “Star Trek.”
