The Modern Mind Needs a New Kind of Reset In a world that’s always on, your mind deserves a moment to switch off. Whether you are a creative battling a mental block, a professional burning the candle at both ends, or simply someone seeking a moment of peace, SeptaSync is your personal audio sanctuary. How It Works: The Science of SeptaSync SeptaSync is built on seven layered binaural beats and 14 carrier frequencies — a unique formula designed to gently guide your brain toward balance. Think of it as a language your brain can understand. This process, known as brainwave entrainment, encourages neural synchronization, helping to support states associated with relaxation, focus, and rest. The result? A drug-free way to ease daily stress, unwind from burnout, and drift more effortlessly into deep, restorative sleep. The science is in the sound. Any pair of stereo headphones will work. We combine the ancient wisdom of sound with modern neuroscience to create a powerful tool for mental wellness. By simply putting on your stereo headphones, you can step out of the noise and into a state of deep relaxation. Your Journey to Inner Peace Our growing library (currently 17 tracks, with more on the way) offers a soundscape for every state of mind: For Deep Sleep: Let the day fade away as layered frequencies soften your thoughts and slow your pace, guiding you into “Sleepless Rest.” For Focus & Clarity: Break through mental fog and sharpen your concentration, helping you feel as if you can “Dream while you’re awake.” For Stress & Tension: Gently soothe a racing mind, bringing your emotions back into balance and helping wash away the pressure of the day. Designed for You At Virya LLC, we blend neuroscience with compassionate design. We believe true wellness should feel personal, secure, and empowering. That’s why every track is crafted with precision audio engineering to help you reset, refocus, and reconnect with yourself. For the best experience, find a relaxed position, dim the lights, and let the sound take over.“Take a deep breath and let the day fade away.

Verdict

The call

The clearest difference is monetization model: SeptaSync at freemium against Hemi's subscription. SeptaSync also leads on review sentiment (67% vs 32%). Hemi's advantage is rating (4.4 vs 4.0) and ratings volume (2.5K vs 4). On price, update cadence, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Hemi sells 2 in-app purchases, starting at $14.99 per month and SeptaSync sells 6 in-app purchases, starting at $10.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Hemi holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Hemi has 2.5K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 32% of Hemi's written reviews are positive against 67% of SeptaSync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Hemi ships an update every 2 weeks, SeptaSync every 3 weeks. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
