Koch Trainer is a morse code trainer that uses the Koch Method developed by the German psychologist Ludwig Koch in the 1930's. The method basically states that you should learn morse code at the speed you expect to receive, by training your reflexes to respond to code sent at 20 WPM you'll learn the code much faster.
Thank you and 73,

Chords extracted from scale harmonization can now be sorted following the scale's notes order instead of fifths.
You can control this in "Scales Settings", "Harmonization" section.
You can now rotate your device to display scale fingerings in landscape when coming from reverse search or harmonization on iPhones.
I've also fixed a glitch in landscape mode for arpeggios and scale fingerings.
You can now automatically sort all songs in a collection alphabetically when editing it.
Fixes:
Fixed an issue when inserting items into collections.
Fixed an issue when reimporting song with lines starting with spaces.
Fixed collections thumbnails using the wrong tint when using dark mode.
Fixed some buttons with text written with the wrong color.
As always, your feedback is highly appreciated.
If you like Chord!, please rate it in the App Store!
Thank you very much!
