未完成的诗 vs dB Meter

This is a deeply personal product that I created out of my own necessity. I often use quiet piano pieces as background music while working and greatly enjoy browsing through serene, beautiful images. I wanted to combine these elements into a single product, which also includes a diary feature. All data is stored locally and never uploaded, with the option to export as CSV files. It's perfect for capturing your daily inspirations.
