User Reviews

Perfect Tempo provides strong tempo control for practice and learning, plus an easy, elegant UI and support for local files and looping sections. It’s popular for teaching and routine practice. However, recurring issues include broken Apple Music integration after updates, missing autoplay, audio distortions at tempo changes, bugs in features like pitch/loops, and mixed value for the price. These themes appear across multiple reviews.

Pros

Precise tempo control that enhances practice and learning of songs and solos.
Very user-friendly, simple, and elegant UI that stays out of the way.
Supports local files and easy management of playlists/setlists for practice.
Ability to loop or repeat sections for focused practice.
Used by teachers and choreographers for teaching and practice.

Cons

Apple Music compatibility and playback are broken by updates, making Apple Music songs inaccessible or unusable for many users.
Lack of autoplay or reliable automatic progression to the next track in a playlist.
Audio quality distortion or compression when tempo is adjusted (especially at low or higher tempos).
Bugs and glitches affecting features like pitch shift, loop start/end, and setlist behavior after updates.
Mixed perceived value for the price, with some users feeling it’s worthwhile and others feeling it’s not worth the cost given the issues.

[2026.01.31] fully blind user 8+ years using this now for a few months and love it, only tiny complaint is no song lookup by artist, and it’s understandable but I wish there was one like in Apple Music, instead of search

I like the app but it doesn’t suit my needs. I can understand and overlook the slight change in sound when the tempo is adjusted. I can work with that. What I thought it could do was sync the whole playlist to the same tempo. I wanted to use it for a fitness class. But I will just go back to the way I was doing it and live with the slight changes in tempo for each song. If you ever add that feature, I would use it all the time.

Overall these reviews are harsh and don’t seem fair so I wanted to counterbalance. Perfect Tempo has always worked great for me and does just what it says it will do. I do wish it had the ability to transpose as well, but otherwise it works flawlessly and I’ve used it to teach music, practice my own music, and more! Big fan!
