6 Best Free Sleep Apps (2026) — No Subscription
Most sleep apps lock their best features behind a subscription. We found the ones that actually let you sleep well for free - plus the ones with one-time purchase options so you never see another renewal charge.
Quick Comparison
| App | Free Tier | Paid Option | Best For |
|---|---|---|---|

| Dark Noise | No free tier | $5.99 one-time (iOS only) | iOS power users, Shortcuts |
The Subscription Problem
Sleep apps have a subscription problem. Calm costs $70/year. Headspace costs $70/year. BetterSleep charges a subscription for its full sound library. Over three years, that is $210+ for an app you use at bedtime to play ambient sounds.
The alternative is apps that either have genuinely usable free tiers or charge a one-time price. They exist - they are just harder to find because subscription apps dominate the marketing budgets on the app stores. For a broader look at paid and free options, see our best sleep apps roundup.
1. Momental - Best Free Sleep Sounds App
Momental is a focused sleep soundscape app with 60+ ambient sounds covering nature sounds, white/pink/brown noise, and solfeggio frequencies (174-963 Hz). It is designed for people who want to fall asleep to calming sounds without navigating courses, social features, or subscription prompts.
The free tier is genuinely usable - many sounds are available without paying, and all core features work (timer, session modes, sleep tracking). Premium unlocks the full library via a one-time purchase. No subscription. No recurring charges. No annual renewals.
What makes it stand out: advanced timer with warmup periods and interval bells, four session modes (sleep, relax, focus, meditate), streaks and a sleep journal, and cross-device sync across iOS and Android.
2. Insight Timer - Largest Free Meditation Library
Insight Timer has the largest free meditation library of any app - over 100,000 guided sessions from teachers around the world. Its sleep content includes sleep music, yoga nidra, body scans, and ambient soundscapes.
The free tier is remarkably generous compared to competitors. You get a customizable meditation timer, community features, live events, and most of the library without paying. The premium tier ($60/year) adds offline access and structured courses.
The trade-offs: the sleep sound selection is not as deep as dedicated sleep apps, the interface can feel cluttered, and the community features are not for everyone.
3. myNoise - Donation-Based Noise Generator
myNoise runs on a donation model - core generators are free with no ads, and donations unlock the full library of 200+ noise generators. Each generator has individual frequency sliders for precise customization.
It is the most customizable option on this list. The calibration feature adjusts output to your hearing profile, and animation modes prevent habituation. It lacks sleep-specific features (no timer, no tracking) but is excellent for pure sound generation.
4. White Noise Lite - Free with Ads
White Noise Lite is one of the longest-running white noise apps on the app stores. It is fully functional for free - 40+ ambient sounds, a mixer, alarm integration, and background playback. The only cost is banner ads, which you can remove for $1.99.
The interface is dated but reliable. It does exactly what it promises with minimal battery drain. For people who just want white noise with no frills, it works.
5. Sleep Cycle - Free Sleep Tracking
Sleep Cycle is primarily a sleep tracker, not a sound app. But its free tier includes basic sleep tracking with a smart alarm that wakes you during light sleep. It monitors sleep phases using your phone's sensors and provides morning reports on sleep quality.
The premium tier ($40/year) adds detailed analytics, snore detection, and historical trends. If you want data about your sleep rather than sounds to fall asleep to, Sleep Cycle is the best free option.
6. Dark Noise - One-Time Purchase (iOS)
Dark Noise is not free, but at $5.99 one-time it is worth mentioning as a subscription-free alternative. It offers 50+ sounds with deep iOS integration - Shortcuts, widgets, Siri, and iCloud sync.
iOS only. No Android version.

| Headspace | $70 | $210 | $350 |
