Better when it worked

I can login to the regular RiffTrax app, no problem. This one? It doesn’t work. Same credentials. Login Failed every time. It used to work a few months ago. It’s a bummer because I bought twenty or so “Just the Riffs”, and now they’re stuck behind a non-working app. 2026 sucks. All the shorts and videos I purchased work in the main app. For some reason there are two apps.

Worked perfectly

Downloaded a riff track and the app began audio playback automatically, zero problems. I did have to wait for dialogue in the film (it wasn’t able to sync until the characters began talking) but that wasn’t really a problem. Love this so far.

Wow. Other Reviewers are A-Holes!

Some of them are all “I absolutely LOVE this but it has one small flaw, so….3 stars. Maybe 2!” Absolutely hilarious. And so much fun! Connected from the iPad right to Alexa (like having smartasses in the living room)! And put a bunch on our wish list. Easy to use and sync! So much fun.

Don’t be a db and pirate. Support these guys!

This needs to integrate Rifftrax Friends

That way everyone could subscribe and use this app or perhaps a separate dedicated Rifftrax Friends app that’s the only way I’ll resubscribe.

love rifftrax but…

the devs are non-responsive and several of the titles have sound or sync issues. Speaking on sync issues, the mechanism to match up your film with the riff seems pretty outdated. Archaic almost. Great riffs, super funny mostly but the tech issues are a bummer.

EDIT: Emails were sent to support prior to my review. No response was received and no, it’s not any simple user error thing you mentioned. The other riffs have been fine. The file for the riff in question is corrupted. Fan shouldn’t have to stay on you about these encoding issues for paid riffs. Check your email and follow along with ur iPhone if you like. You’ll see the issue and hopefully fix it. Can’t imagine it being harder than just formatting it again for this app.

Response from developer

Hi there, could you please submit a ticket at rifftrax.com/help so we can work with you directly? If there is a sync issue, most likely the reason is because the movie you're watching is different than the one we recorded to. Please drop us a message (use the app's "Report a problem" option to submit a log file, if you can) and we'd be glad to look into it!
