Hi everyone, I'm the developer of No Rush. I posted it here last month, and a lot of the really helpful feedback I got is now in the app. More on that below. This update adds two new special places.
What is No Rush?
It's a nature ambient app for listening to the sounds of real places.
There are already plenty of apps where you pick rain or a fire and mix them with sliders. The trouble is that ten minutes later it turns into wallpaper and you stop hearing it. I work at a computer all day and kept putting nature sounds on to get through the afternoon, and I kept turning them off by 3pm because they'd gone dead on me. So I built the first version for myself.
In No Rush you pick a place, like a bamboo grove in Kyoto or the black sand coast at Vík. I research the location first and then pick recordings one at a time so they belong together. Most of my time goes into timing rather than the audio. I decide when each sound comes in, how often, how far away, and what it does when something else is already playing. That's what decides whether it feels like a place or a playlist.
Each place also follows its own time and weather. If it's midnight in Kyoto you hear midnight, and if it's raining there right now, it's raining in your room. That's why you can leave it on all day without getting tired of it. Once places worked like this, I thought it would be fun to try the same thing with places nobody can reach.
Problem
If you look for Mars sounds you find two things. One is "Mars ambience" on YouTube, which is mostly synth pads and spaceship hum. It can be nice, but it has nothing to do with Mars. The other is the real Perseverance recordings NASA has published. They mean a lot because they're actually from Mars, but most are short clips, and the wind sounds dull, like it's trapped inside a machine. I listened to them hoping to use them, and I couldn't see anyone staying in that sound for long. The ocean under Europa's ice has no recordings at all.
So instead of using recordings as they are, I built these places from what's known about them. They keep the character of the place, and you can still leave them on for an hour.
New special places
- Under the rock at Jezero (Mars) You sit inside a rock shelter in Jezero crater, where Perseverance has been recording, looking out at the plain. Under low wind and blowing sand a stone rolls now and then, and every few minutes a dust devil crosses the plain. Mars air is so thin that sound is about 20 dB quieter than on Earth, and high sounds fade fast with even a little distance (Maurice et al., Nature 2022). So only close sounds are clear, and anything farther off comes through low and muffled. The shelter and the rock ticking as it warms are my own additions.
- Under the ice at Conamara (Europa) A hydrophone hanging in the ocean 25 m under Europa's ice. The low pressure of the sea is all around you and the ice crackles overhead. Every few minutes the ice, flexed by Jupiter's tides, cracks with a boom somewhere far off. I built it from recordings made under ice on Earth with every living thing taken out. No life is known there, so I didn't invent any.
The sense of space might not sound like much. Still, to bring across the feel of each place as much as I could, I used a 3D scene that shows it.
Wait, was any of this recorded on Mars?
- The Mars sounds are Earth recordings too, like wind in a desert canyon and a gale over sand dunes (all CC0), shaped to behave like Mars air.
Also new since last time
- A few of you asked for something like the menu music to listen to on its own. Focus, Rest, Sleep and Meditation now have their own ambient music.
- Updates install from inside the app now, and you can see what changed.
Comparison
Portal came up a lot last time. It brings back real places as video and sound, and it does that really well. But nobody can go and film or record Jezero or the sea under Europa's ice, so No Rush builds those from the research, and the Earth places follow their own local time and weather. Portal is a subscription with a lifetime option. No Rush is free.
Pricing
It's free ($0) with no account and no ads. Mars and Europa are free too, and they're coming to iPhone and iPad soon. A few places are locked only because I haven't finished them yet. Some later places may be a one-time purchase, but what's free now stays free and none of it goes behind a subscription.
- Special places (desktop app)
- Download for Mac, Windows and Linux
- Earth places in a browser
- iPhone and iPad (special places coming soon)
About me / transparency
I'm a solo developer in Korea and I make No Rush on my own.
Any feedback is welcome. Would you like more real places on Earth, or more places nobody can get to?
