| 3. | G2 | 98.0 Hz |
| 2. | D3 | 146.8 Hz |

How to tune
- Press “Start tuning” and allow the microphone. The sound stays in your browser and is never uploaded.
- Start with the A string, then D, G and finally C, checking each against the string you've just tuned.
- On the low C string, use a slow, heavy bow so there's plenty of fundamental to measure.
- Hold your phone in front of the instrument at the height of the bridge, not behind it.
- When the needle sits in the green middle zone (±3 cents), the string is in tune. Anything within 5 cents sounds in tune to the ear.
