We are doing our best to keep the price as low as possible. However, we have to redistribute money to copyright holders on a monthly basis for each Chord ai Pro user. Hence we are unable to lower the current price as the app would not be profitable anymore.
If you do not need access to YouTube or SoundCloud, you can try Chord ai’s sister app called MusicMemos (see What is the MusicMemos app?) which is almost identical but much cheaper: MusicMemos
