Seventeen best apps for changing music tempo on Android and iPhone.

1. Up Tempo

Cost: Free (Free), Up Tempo Premium ($4.99/month)

Up Tempo is my go-to app for changing music tempo on my phone, blowing away other similar apps with its intuitive design and powerful features. Unlike others that struggle with audio quality, Up Tempo maintains crystal-clear sound even at extreme speed adjustments, thanks to its advanced algorithms. With over 1.8 million downloads and consistently high ratings, its popularity speaks for itself.

2. Music Speed Changer

Download: Android iOS

Cost: Free (Free), Music Speed Changer Premium ($2.99/month)

Music Speed Changer is a fantastic app to change music tempo, offering precise control over both speed and pitch independently, making it ideal for musicians practicing tricky passages or for anyone wanting to adjust audiobook playback speed. While lauded for its functionality and ease of use – users consistently praise it as "the best app right now" – some drawbacks exist, including jarringly loud and intrusive ads (even with personalized ads disabled) that interrupt playback and require a frustrating manual restart of the music. Despite occasional glitches like file upload failures and sudden app crashes, the core functionality of tempo adjustment is powerful and reliable enough that many users, like myself, find it well worth using, even with the ad inconveniences.

Key Features:

• Adjust playback speed without pitch change.
• Alter pitch independently of tempo.
• Save modified audio files.

This allows for effortless learning and practice, as verified by over 150,000 downloads and consistently high user ratings on app stores. I chose Anytune because its superior audio quality, combined with its extensive features like looping and marking, makes practicing music way easier and more enjoyable.

Key Features:
