| Fact | Centerline | ChromTuner |
|---|---|---|
| Notable limit | All Strings remembers individual readings but does not measure a chord at once; chromatic mode does not cover the full piano range or a bass guitar’s lowest notes. | The maker says full-band rehearsals and noisy stages can make room-microphone tuning unreliable, recommending a wired pickup or audio-interface DI input. |
| Support | Questions or feedback can be sent to [email protected]. | The Mac purchase includes direct email support from the developer, and the FAQ says replies usually arrive within a few hours. |
