Hush Noise

Features
Read full description

Meet Hush - a tiny, elegant sound studio for focus, relaxation, and sleep. No recurring subscription or in-app purchases. Tap Play for a great default mix, or open Studio to fine-tune every detail: beat rate, base tone, and the exact “color” of noise from Brown to Violet. Headphones recommended for binaural beats. Why you’ll like it • Press play, done. A balanced Focus/Unwind/Sleep preset starts instantly. • Smooth by design. Every change ramps in—no clicks, pops, or jumps. • Dial it in. Set beat rate (0.5–35 Hz), base tone, and tone/noise mix with fine control. • Headphone-smart. Detects headphones and offers a friendly mono preview when they’re not. • Set and forget. 5/15/30-minute or ∞ timers with a gentle fade-out at the end. • Comfort first. Optional safe-volume cap keeps listening easy on the ears. • Made to feel right. Big Play button, haptic detents at meaningful values, clear labels. • Always ready. Works offline—no account, no sign-in, no distractions. Hush can play two things at once: 1. Binaural beat - two nearby tones (one per ear) that create a perceived beat at their difference. 2. Colored noise - white/pink/brown/blue/violet shaped to sound darker or brighter. Mix them to taste, save your vibe, and let the timer handle the rest. Notes • Binaural beats require stereo headphones to function as intended. • Hush is for relaxation and focus only. It is not a medical device and makes no health claims.

FlowStudy is a focus timer designed specifically for ADHD brains. Unlike traditional pomodoro timers that interrupt your flow with rigid breaks, FlowStudy respects your hyperfocus and helps you work with your brain, not against it. DESIGNED FOR ADHD Traditional timers force you to stop when you are finally in the zone. FlowStudy lets you keep going. When your session ends, simply tap "Keep Going" to extend your focus without losing momentum. START SMALL, BUILD MOMENTUM Task paralysis is real. That is why FlowStudy features a prominent "Just 5 Minutes" button. Starting is the hardest part, and 5 minutes is all you need to get going. Most people keep going once they start. VISUAL TIME FOR TIME-BLIND BRAINS A large, calming progress ring shows exactly how much time remains. No more guessing, no more time blindness. The ring changes color as you approach the end: blue for active focus, yellow for wrap-up, and teal for completion. GUILT-FREE BY DESIGN No streaks. No shame. No punishment for missed days.
