## Description

**Up Tempo** is an all-in-one music practice tool and audio editor for singers, instrumentalists, transcribers, and producers. Change pitch or speed independently, reverse playback, create precise A/B loops, and save settings for every track. Use the waveform editor to trim audio, add fades, mix tracks, and export in MP3, M4A, or lossless FLAC formats.

With Pro, separate songs into vocals, drums, bass, and other stems directly on your device—without an account or upload. Record audio, apply EQ, reverb, delay, compression, filters, distortion, and other studio effects. The free version includes pitch and tempo adjustment, looping, trimming, fading, two-track mixing, and export, while Pro adds advanced separation, recording, effects, unlimited markers, and multitrack editing with a one-time purchase.

## Review summary

Users praise Uptempo for real-time speed/ pitch control and a feature-rich, ad-free experience with a one-time purchase. However, recurring issues include broken exports, file import/load bugs, and noticeable lag during use. Some reviews note paywalls restricting voice recording. Overall, it’s powerful for editing and practicing with backing tracks, but stability and file-management problems detract from the experience.

### Pros

- Real-time independent speed and pitch control (varispeed) during playback.
- One-time paid version is affordable, has no ads, and includes vocal separation.
- Easy to navigate interface with solid import options (MP3 from iTunes or files).
- Feature-rich editing suite (EQ, delay, reverb) with an interactive waveform and editable saves.

### Cons

- Export functionality is unreliable or broken across updates (exports fail or nothing is saved).
- File import/load bugs: added files disappear, loading from iPhone fails, and occasional file-access issues.
- Significant lag/latency during playback and editing (choppy performance, delays after stopping, issues when the device sleeps).
- Voice recording and some features are gated behind a paywall (restricted behind premium access).
