BetterSleep is a sleep tracking and relaxation app from BetterSleep Health, available for free on both Google Play and the App Store. The download is free, though a subscription unlocks the full content library. Ads appear occasionally in the free version, and in-app purchases are part of the experience. Install numbers sit in the tens of millions, which says something about how many people look for help winding down at night.

Opening the app greets you with a short questionnaire about sleep habits, stress levels, and daily routines. From there, it builds a loose profile and suggests soundscapes, guided meditations, or breathing exercises. Tracks range from rain and ocean waves to piano loops and ambient noise, and most can be layered. A built-in tracker logs sleep duration once you set a bedtime and wake window, then shows a simple graph the next morning. I found the mixer genuinely useful: rain underneath soft piano, with a low-volume hum on top, is my usual setup. The interface stays calm and dark, which matters when you are staring at a screen at 11 p.m.

Plenty of apps do sleep sounds or meditation, but few combine both in one place. Calm leans heavily toward meditation courses, while Sleep Cycle focuses on tracking and smart alarms. BetterSleep sits somewhere in the middle, offering a wide sound library alongside basic tracking and guided sessions. The design feels less polished than Calm in places, yet the sound variety is broader. For someone who mainly wants background audio at night rather than a full wellness program, the focus here is easier to appreciate.

• Sound mixing lets you combine multiple tracks and adjust each volume separately, so the final result feels personal rather than preset.
• Sleep tracking runs quietly in the background and produces a straightforward duration chart each morning, without overwhelming you with data.
• Guided breathing and meditation sessions are short and easy to follow, which suits people who dislike long, slow introductions.
• Compared with Calm, the range of ambient sounds is noticeably larger, though the meditation library is smaller and less structured.

• Falling asleep feels faster on nights when I use a mixed soundscape instead of silence.
• The bedtime reminder is gentle enough that it does not feel like another notification to ignore.
• Having tracking and sounds in one app removes the need to switch between two programs.
• A short breathing session works well as a reset during a stressful afternoon, not just at night.

• Some of the better soundscapes and meditation courses sit behind the subscription, which limits the free version.
• The sleep tracker is basic compared with dedicated devices or more advanced apps; it will not detect snoring or detailed sleep stages.
• Occasional ads in the free version interrupt the calm mood the app tries to create.
• The home screen can feel cluttered once you save many favorites, and finding a specific track takes a few extra taps.
