I initially started this project for personal use only. However, I soon realized that more people had requested Spartial's functionality as a native Spotify feature.
This led to me researching about whether I could publish this app in the App Store and Play Store (Without having to manually enter the client ID). To my disappointment, this wasn't possible due to restrictions in the Spotify developer policy.
However, I still wanted to publish my work, even if it's just for educational purpose.
