From the guys who brought you Mystery Science Theater 3000, RiffTrax makes movies FUNNY! Our hilarious commentaries turn some of the biggest blockbusters (and cheesiest B-movies) into comedy hits.

“The RiffTrax app syncs everything up perfectly.” - CNET

“Rifftrax app takes the guesswork out of syncing jokes to film. It’s easier than ever to sync MST3K-like commentary. The app uses your device’s microphone to listen for a movie and automatically syncs Rifftrax playback to the film. It’s simple and easy...” - Engadget

“The app can recognize movies from Netflix, iTunes, Amazon Video, DVDs, Blu-rays, your TV, computer, and other streams.” - High-Def Digest

“Video content (VOD) coming soon!” - RiffTrax Team

Using the app, you can download these "riffs" on blockbuster films like Twilight, Jurassic Park, Star Wars and more! The app listens to the movie, using your device's microphone, and automatically synchronizes the commentary to play along with perfect timing. Presto! That movie is now a comedy smash.

I have enjoyed a RiffTrax since 2008. So, when I saw this app last week, I had to download it especially to try out the microphone syncing. Well, being the new year, I got $10 to spend from RiffTrax. So, through the app, I purchase a riff I don’t have. Well, alas, it’s not quite obvious that the app uses iTunes account to purchase even though I was signed into my RiffTrax account. I’ll have to chalk this up to my own stupidity but it would have been nice to know at least like with in app purchases like some apps prominently display in the app description or to at least give you a choice.

Developer Response ,

Hi there! Apologies for the issue. Unfortunately this is in-app purchase behavior in all app platforms; they require you use your app store billing information for the actual purchase. That being said, as long as your signed into the app, it should still sync with your site account/Library. However, we're always looking to improve, and we'll work to find a way to make this more clear throughout the app.

Some Rough Spots But Still a Gem

This is one of the most underrated apps in the App Store. It may not be perfect interface-wise but syncing the riffs is a perfect use case for the tech. Also, the content is good and incredibly cheap. A few dollars to turn an otherwise unwatchable movie into a good comedy? Count me in. I think Apple should feature it.

Re-reading my own review I realize this actually sounds like a fake review! So let me just say this: watch the movie 300 with the rifftrax going. You will 100% agree that it is the definitive version of this movie. There aren’t many apps that possess the ability to utterly transform and elevate the quality of what is already considered premium content. That’s why I think Apple should promote it..

Love RiiffTrax but the app needs help PLEASE!

My family and I have been watching you guys for years as MST3K and RiffTrax. When we stumbled upon the jokes to sync with our movies OMG we kids in a candy store. Our kids couldn’t wait to listen to you Riff their movies. The issue is that the app does not allow for syncing through any Bluetooth device. Is there a reason that you may know of? We tried quite literally every single Bluetooth speaker in our home and then even tried to do it the old fashion way and bypass with plugging in an aux cord but alas nope. The app will not play any sound unless it’s directly from the phone. It would be great if this feature could be fixed/updated so the Riffs could be heard for one and all.
Thanks and again you guys are awesome!
