Hertzly is a speaker cleaner and audio toolkit for iPhone. Play cleaning tones, check speakers, generate test signals, and measure approximate sound level — all on this device. WHAT YOU CAN DO • Clear — play a high-frequency cleaning cycle intended to help shake moisture or debris from speaker grills. Results vary. It does not repair hardware and does not guarantee water or dust removal. • Speaker Test — play a test sweep and see an on-device frequency-response estimate. For personal reference only, not a lab measurement. • Generator — sine, sweep, square, triangle, sawtooth, white/pink noise, and burst, with frequency, volume, left/right output, and an optional auto-stop timer. • dB Meter — approximate sound-level readings with the microphone. Informational only, not a calibrated meter, and not for safety, workplace, or legal use. • Presets — built-in test tones plus custom presets saved on this iPhone. TRY EACH TOOL ONCE Each tool includes one complimentary use: one cleaning cycle, one Speaker Test, one Generator playback, one dB Meter session, and one custom preset. After that, that tool requires Hertzly Premium. HERTZLY PREMIUM — IN-APP PURCHASE (OPTIONAL SUBSCRIPTION) Hertzly Premium is not included with the free download. It is an auto-renewable Weekly or Yearly subscription sold separately through Apple. Premium unlocks unlimited use of every tool, extra generator options, custom presets, and background playback. Microphone is used only while Speaker Test or dB Meter is running. Audio stays on this iPhone, is not uploaded, and is not saved as a recording. Hertzly is not a medical device and is not a professional sound-level meter. Start at a low volume. Do not hold the phone against your ear during playback or cleaning. SUBSCRIPTIONS Hertzly Premium is available as an auto-renewable subscription: • Weekly • Yearly Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless you cancel at least 24 hours before the current period ends. Your account is charged for renewal within 24 hours before the period ends. Manage or cancel in iPhone Settings → Apple ID → Subscriptions. Any unused portion of a free trial, if offered, is forfeited when you buy a subscription.
