Amazing music! *2026-02-02* Spindles has been a game changer when it comes to my workouts each morning! The Focus album has helped me reach a whole new level of concentration. ⭐️⭐️⭐️⭐️⭐️ **Developer response:** Thank you User CSR for your support of the Spindles organization. :) ### 5/5 — 5 stars all around *2025-12-09* Spindles has been incredibly impactful when it comes to helping me fall asleep at night. It is truly an amazing tool with a wide variety of quality tracks to choose from. Would highly recommend! **Developer response:** Yay! Glad you find it useful and thank you for the kind words. 🙏🏻 ### 5/5 — Worth it *2025-12-08* Really cool app obviously made by a real artist. Not like other music apps because of its uniqueness and diversity. I originally got it for sleep but now I also use it for that flow state jam mode, when I’m journaling, working on a project, taking walks, or just craving a nice vibe to add to the moment. You should try it!!!!!!!!! **Developer response:** Wow, thank you so much for the kind words. Makes me happy that it connects! Cheers, BR ### 5/5 — We love this app! *2024-11-20* I’ve been using spindles to help my boys focus during homework and to help them relax and fall asleep at night. The quality and effectiveness of the sounds is unlike any other soundscape app I’ve used. There is a wide variety which is really nice. The boys love it and so do I. We highly recommended Spindles. **Developer response:** Thanks for the insights on how you use Spindles and thanks for the review. 😉 ### 5/5 — Lovely tunes *2024-11-13* Great ambience to work and study to. ### 5/5 — Highly Recommend for Focus Tracks *2024-11-06* I use Spindles for studying, work, and to relax. I am impressed with the quality and variation of tracks. There is a feature that allows a soundscape to play on top of the track, which is very unique. The soundscapes are original and enhance the listening experience. While I mostly use it for focus, I have also enjoyed it during working out, everyday listening, etc. I highly recommend Spindles! **Developer response:** Thanks, buddy (I just figured out how to respond to reviews, haha!) -BR ## Frequently asked questions about Spindles ### What is Spindles?

Version 2.8 also introduces a redesigned Home screen that brings Focus Collection, Sleep Spindles, and the full catalog into clearer view. ### 2.8 — 2026-08-10 Focus is fragile. Sleep is elusive. Analog & acoustic music, natural soundscapes, and custom noise — informed by research on attention, sleep, and sound perception. Now with a Home Screen Widget and one-tap access to rotating Today's Atmospheres. Focus Collection is Spindles’ dedicated focus system, offering three distinct paths to sustained attention. Harmonic Fields provides distraction-free expansive atmospheres, Melodic Focus offers evolving melodies and gentle motion, and ADHD Beats delivers rhythmic structure for restless minds. Together they form a handcrafted approach to deep work built from analog synthesis, vintage instruments, custom noise profiles, and natural recordings. Rather than looping a single texture or shuffling tracks, these listening environments are designed to support concentration gently and sustainably — helping you drop into flow and stay there. Sleep Spindles is a dedicated sleep system designed around the full arc of a night’s rest. Rather than playing a single track on loop, Sleep Spindles moves through three intentional stages: a calming introduction to ease you toward sleep, a deep overnight listening environment to keep you there, and a gentle Wake Transition to bring you back gradually. Every sound is chosen and sequenced with the same analog and acoustic care that defines the rest of Spindles. Beyond Focus Collection and Sleep Spindles, Spindles opens into an extensive sound environment spanning ten listening contexts — Sleep, Focus, Calm, Meditation, Yoga, Movement, Morning, Soundscapes, Tinnitus, and Acoustic. Explore purpose-composed music, immersive field recordings, custom noise profiles, binaural beats, and a curated collection of classical and contemporary piano repertoire recorded on a concert grand piano in a softly reverberant space. Together they form a flexible toolkit for focus, sleep, calm, meditation, and everyday listening. Analog Craft.
