🔊 Issues With Sound


I’ve noticed after updating my phone 📱 iOS 11, there’s been an issue with the sound lately. If I swipe up to open the control center while watching a video in the app, the audio from the video becomes choppy while swiping up the control center. I’ve also noticed that when I leave the app, and then go back into the app, the audio from previous videos I’ve listened to will be playing, but the sound will be very choppy. The only way I could fix that was to fully close the app, then reopen it. Hopefully soon a new update will be available to fix these issues I’m having. But everything else about the app is working well

This app blows. It claims it has pitch shift on it (which it does) however the function is completely useless. What's the point of incorporating a pitch shift in the app if the pitch shift isn't implemented in the final exported video? Then they make you pay for doing more than one export. So i'm thinking "hey maybe they'll let me change the pitch if I pay $1.99" but that's their scam. The app advertises pitch shift in the title however does not support it which is misleading. I will never download an app from this producer again because he/she is clearly in the app making business for a profit and to scam rather than actually helping and benefiting iPhone users with quality applications.

Developer Response

Thanks for your comment.
We added the function to save to cameraroll corresponding to speed and pitch change.
Please check the latest version.

Good, but needs more convenience


Been looking for an app that could do this for the longest. Only complaint is that it needs to be easier to seek forward & back through the video. I'd recommend adding forward & back buttons at the bottom of the player so we won't constantly have to reach to the top of the screen to do so.
