Liveaboard + app developer — I built a music player with a proper red night mode, mostly because of cabin life.
Upfront: I built this, so this is a developer post, not a "look what I found." But it came directly out of living aboard, so I'm hoping it's relevant here rather than just spam.
The thing that finally pushed me to build it: I wanted music or a podcast in the evening without a screen full of white-blue light blasting the cabin every time I picked up my phone. At anchor with someone else already turned in, even reaching for the phone to skip a track lights the whole place up. Every "dark mode" I tried is still grey with bright text — better than nothing, but it still kills your night adaptation and it's still glaringly obvious in a dark cabin.
So I built an Android music player (Aether Hi-Res Music Player) with a real red night mode — the whole interface goes red-on-black, not a dark-grey theme with a red tint. The idea is you can change tracks or find a podcast at night without lighting up the cabin or wrecking the dark adaptation you want for a night watch or an anchor check.
It does the normal stuff well too — hi-res audio, equaliser, works offline (no signal at anchor anyway) — but the red mode is the part I think this crowd will actually get.
I'd really value feedback from people currently living aboard, since you'll be testing it in exactly the conditions it's meant for. Is it red enough in a genuinely dark cabin, dim enough, anything you'd change? Not dropping a link unless people want it — happy to point you to it if you're interested, and happy to answer anything about how it works.
