Wampy, interface addon for Linux-based Walkmans
Wampy is an interface addon for modern Linux-based Walkmans, which allows you to switch between standard interface and custom one using hardware Hold switch. The project was born out of handful of standard UI nitpicks and "can I make a prettier UI?". There is no Rockbox port for my device (NW-A55), so I did a UI myself, unlocking and adding various features along the way, such as: - Winamp 2 skin support - Custom cassette skins - Digital clock skin ported from iPod Nano 7g - Audio amplification table editor for S-Master HX - All audio filters are available regardless of firmware - Per-song…

i wanted to change the habit of reaching for my phone in the morning and doomscrolling away an hour so i built an app to help me. now i have to literally touch grass before accessing my most distracting apps the app is built in swiftui, uses the screen time apis provided by apple and google vision to recognise grass or not i'd love to get your thoughts on the concept.
