Oak - Meditation & Breathing

Oak has been quietly doing its job since 2017, and a March 2026 update shows Nyllon still cares about the product. The app covers guided mindful and loving-kindness meditations, sleep meditations, unguided sessions stretching from five minutes all the way to 24 hours, and dedicated breathing exercises. It lets you pick your instructor gender, dial in session length, and layer in background sounds or pure silence. Nothing here feels bloated, which is either a strength or a limitation depending on what you bring to it.

The Unguided Range Is the Real Draw

Most meditation apps treat unguided mode as an afterthought, but Oak lets you run a session anywhere from five minutes to a full 24 hours. That upper ceiling is genuinely unusual and makes the app useful for experienced practitioners who just want a timer with ambient sound rather than a narrator. Pairing that flexibility with selectable background tracks like bells and blocks means you can shape the environment without switching to a separate app.

Where It Stays Conservative

Oak does not appear to offer body-scan sessions, movement-based content, or anything beyond its defined meditation and breathing categories. At 170 MB it is a reasonably sized install, but users expecting a broad content library may find the scope narrow. The free tier structure is not fully transparent from store materials, so potential in-app purchase costs remain a question mark before you commit to building a streak here.

Who Actually Fits Here

Oak suits someone who wants a clean, low-friction entry point into meditation without the social feeds and gamification layers that crowd rival apps. The choice of male or female instructor and the five-to-30-minute guided range covers most casual-to-intermediate needs. A 32,000-rating average of 4.84 across eight years of active use suggests the core audience keeps returning, which is a more honest signal than any launch-week spike.
