Noctra is an ad-free white noise & sleep sounds app for iPhone and Android. An on-device room-sound scan listens to your space and suggests the sounds that mask it best. Mix white/brown/pink noise, fan, rain, thunder, ocean and forest layers with individual volumes, set a gentle fade-out timer, and keep playing in the background or on the lock screen. Starts instantly, works offline. Free to start, with intentionally cheap monthly/yearly plans. iOS: apps.apple.com/app/id6786351292

Hi Product Hunt, I built Noctra because I wanted an Android sleep-sound app that starts quickly at bedtime and does not interrupt tired users with ads. What makes it different: - No ads or loud interruptions during playback - Offline white/brown/pink noise, rain, fan, ocean, nature, focus and baby sounds - Layer mixer, favorites, recent sessions and soft fade-out timer - On-device ambient room-sound scan that suggests audio matching the room - Optional monthly/yearly premium is kept very low-cost for extra sounds and routines I would love feedback on the first-session flow, the tagline, and whether the adaptive room-sound idea is clear from the listing.

Feature spotlight: Sleep Winddown, rain that slowly turns into brown noise

Hi everyone, Khoa here. A quick look at a Noctra feature that's easy to miss: one-tap routines.

Sleep Winddown (60 min)

Starts with soft rain while you settle in
Gradually shifts into deep brown noise, with no hard cut between the two
Fades out and stops after 60 minutes
One tap on the home screen, no mixing needed

Which sound should Noctra add next? Blue noise, cat purr, washing machine or shower

Hi everyone, Khoa here.

I'm working on four new sounds for Noctra. Each one needs a clean loop that doesn't click or jump when it repeats, so I'd rather polish the one people actually want first.

The candidates

Blue noise: a brighter, hissier cousin of white noise
Cat purr: a low, steady purr
Washing machine: the rhythmic hum of a running machine
Shower: steady falling water, softer than rain

I launched my sleep app here with 3 upvotes. 3 months later, here's what I got wrong.

Hi PH, Khoa here, solo Flutter dev from Vietnam.

In June I launched Noctra (sleep sounds, no ads). It got 3 points. Fair: I pitched features, not a problem.
