Are there any Apps that are useful to musicians and singers regarding changing or detecting songs etc.?
They are many others which I have not researched, not intend to research, as I am currently happy with these.
| Purpose | App Name | Apple | Android | Free? | Paid | Comment | Link |
| Change the key or tempo of an MP3 file on your device | Anytune | Yes | Yes | $14.99 | Free version should be sufficient | Anytune (Apple) | |
| Anytune | Yes | Anytune Beta (Android) | |||||
| Detect chords on an Mp3 file | The Chord Dedicator | Yes | ? | $2.99 | Not the nicest of interfaces, but it works and shows the chords in a table or dynamically as you replay the song. Supposedly detects from YouTube but I have not tried this. |
The Chord Detector App | |
| Detect chords by listening through your device's microphone | Chord Detector | Yes | ? | $2,99 | Can be useful sometimes but it depends on background noise, closeness to source etc | Chord Detector | |
| Guitar Tuner, Chord lookup, metronome etc | Guitar Toolkit | Yes | Not yet | $2.99 | Very handy for tuning, looking up unfamiliar chords, or hearing the proper timing of a song. I am sure there are many like this also available for android. |

| Decibel meter . for those that would just love to know! ** | Decibel X | Yes | Yes | Not sure of accuracy, but probably useful for relative readings of loudness. | Decibel X (Apple) | ||
| Decibel X | yes | yes | Decibel X (Android) |
According to Centre for Disease Control and Prevention
Sound is measured in decibels (dB).
