## Description

DoubleTune is an advanced tuning app created by professional musicians. It supports tuning a wide range of string instruments—guitars, ukulele, bass, violin, cello, mandolin, viola and more—and helps players learn new chords while refreshing existing ones. It offers a comprehensive set of tuning presets and modes, including Standard and Popular tunings (6 and 12 strings), Open, Modal and Lower tunings, Drop and Chromatic tuners, plus Auto and Manual options. Tune Guard is a safety feature that warns if a string is too tight and highlights the string to help prevent breakage.

In addition to tuning, DoubleTune provides educational games for chord practice and ear training, designed for beginners and seasoned players alike. The app is designed to be fast, simple and accurate, with an intuitive interface and cross-instrument support. Subscriptions unlock PRO features across all instruments and games, with a variety of plans and free trials; billing is handled via the App Store.

## Review summary

Users generally praise the app as a reliable, fast, and easy tuner for guitar/ukulele, but the sentiment is dominated by pricing complaints. A short free trial gives way to a weekly subscription that many view as steep, with frequent reports of auto-renewals and difficulty canceling. Free access has diminished, and many tunings are paywalled or require ads, leading to frustration and uninstallations. Some feedback mentions update-related compatibility issues. Overall, the tuner works well, but the costly subscription model drives most negative sentiment.

### Pros

- Reliable, simple tuner that works well for guitar and ukulele
- Fast to tune and easy to use
- Informational and useful for players across skill levels (beginners to advanced)

### Cons

- Steep weekly subscription after a short free trial (around $7.99–$8 per week, up to ~$400/year)
- Auto-renewal and difficult-to-cancel billing, with reports of charges after attempting to cancel
- Free access largely removed; most tunings are locked behind paywalls or require a subscription
- Billing and privacy concerns, including charges without explicit ongoing permission and trouble removing the app
- Occasional issues after updates (compatibility) and occasional ads or paywalls for extra tunings
