It used to be that in order to get discount tickets, you'd have to get up early and camp out in front of the theatre for rush tickets. Now, all you need is a smartphone and an internet connection. Here are some apps you can use to get discount tickets. Most are available on Google Play for androids and the App Store for iPhones.
You can use the TodayTix App to buy advanced tickets to show or to get lottery and rush tickets. First, select your location (New York, Boston, Chicago, Connecticut, Dallas + Fort Worth, Houston, London, Los Angeles, Melbourne, Philadelphia, San Francisco, Seattle, Sydney, Toronto, or Washington DC). Then, there are multiple ways to use the app. You can search for the show you want to see and see what prices and discounts are available. Or you can search by date you want to see a show or genre. You can also see all shows offering lottery and rush tickets.
You probably know about the TKTS booths in Times Square and other locations that sell discount day-of tickets to Broadway and Off-Broadway shows. There is also an app for that. You can't buy tickets through the app, but you can use it to check what is available at the booths. You can also use it to create lists of shows that you want to see so you can get notified when tickets are available.
This one is only available in the Apple App Store. You can also use it to search for discounts for Broadway and Off-Broadway shows and you can buy tickets through the app. In addition to searching for tickets, you can read Q&As with Broadway actors and other articles on the Daily Scoop on the app.
Use this app to enter the Ham4Ham lottery to win $10 tickets to see "Hamilton" on Broadway, on tour, and anywhere else the show is playing. If you're a "Hamilton" fan, you can also use the app to play trivia, sing karaoke, and take photos with "Hamilton" backgrounds.
The Goldstar App offers discount tickets for shows in New York as well as all over the country. In addition to theatre tickets, there are also offerings for comedy shows, sports, nightlife, concerts, and other events. Sometimes there are even free ticket offers, with an added fee.
