Hearing Test by Tinni vs HalfCaff

Hearing test and tinnitus relief — two powerful tools in one app. Screen your hearing with a clinical-style audiogram, find your tinnitus frequency, and mask it with layered sounds for better sleep. Complete tone generator, binaural beats, and sleep sounds — every sound generated in real time, no downloads required. HEARING CHECK Curious about your hearing across frequencies? The Hearing Check screens your sensitivity at 8 standard audiometric frequencies (250Hz–8kHz) in each ear using a modified Hughson–Westlake staircase with silent catch trials. Get your Hearing Number — a single better-ear score — plus an indicative ASHA tier and an audiogram with the WHO disabling-loss band shaded. Your tinnitus frequency is overlaid if you've matched one. Track your hearing over time in the history view, share a one-page PDF audiogram with your audiologist, and sync results to Apple Health. A screening tool, not a clinical test. FIND YOUR TINNITUS FREQUENCY Stop guessing what pitch you hear. The Frequency Matching Wizard sweeps from 200Hz to 16kHz so you can pinpoint the exact frequency of your ear ringing. Save your profile for personalized sound masking and therapy sessions. TONE GENERATOR & FREQUENCY GENERATOR Generate pure sine, square, sawtooth, and triangle waves from 20Hz to 20,000Hz. Precise frequency control for tinnitus therapy, audio testing, or sound design. BINAURAL BEATS THERAPY Dual-frequency stereo therapy designed for brainwave entrainment (headphones required). Choose your target state: • Delta — deep sleep • Theta — meditation • Alpha — relaxation • Beta — focus SOUND MIXER & COLOR NOISE Layer up sound sources to build your perfect sound masking environment. Mix color noise, tones, and real environmental recordings: • White Noise — full-spectrum masking for ringing in ears • Pink Noise — balanced, natural sound • Brown Noise — deep, low rumble for sleep and focus • Environmental Sounds — campfire, ocean waves, rain, river, waterfall, thunder, wind, and more SLEEP SOUNDS & SLEEP TIMER Tinnitus is often worst at night. Build your perfect sleep sounds mix and let the Sleep Timer fade everything out gradually — your audio disappears before you do. Full lock screen and background audio support keeps it playing all night. NO ACCOUNT. NO INTERNET. NO TRACKING. Everything runs on your device. No account needed, no internet connection required, no data ever leaves your phone. All sounds are generated in real time through pure audio synthesis — no bulky files to download.
