Yap is realtime AI voice translator for real conversations. It automatically detects the language being spoken and translates it into your native tongue in real time, with translated voice and live captions. Traditional translation apps make you choose a language, record a clip, wait for processing, then read or replay the result. Yap is built for the moment itself. Start a live session, choose your native language, and listen naturally. Yap detects foreign speech as it happens so you can understand what someone is saying while the conversation is still moving. Use Yap to understand people live: - Automatically detect the spoken language - Hear foreign speech translated into your native language - Read live captions when audio is hard to catch - Follow conversations at shops, restaurants, hotels, taxis, events, and meetings - Keep up without stopping the moment to type or replay clips Use Yap to speak back: - Talk in your own language and output translated speech - Communicate with people who do not speak your language - Ask questions, clarify details, and keep the exchange natural - Practice real phrases with spoken translation and captions Yap is useful for travel, international work, language learning, daily errands, family conversations, appointments, and any moment where typing into a translator slows everything down. Features: - Automatic spoken language detection - Real-time voice translation - Translated speech output - Live captions - Conversation history - Fast language switching - Phone and room microphone modes - Secure sign-in and account controls Supported target languages include Spanish, Portuguese, French, Japanese, Russian, Chinese, German, Korean, Hindi, Indonesian, Vietnamese, Italian, and English. Yap is designed for live spoken exchanges where timing matters. Open the app, pick your native language, tap to start, and understand foreign speech as it happens. AI translation may not always be perfect and should not be relied on as the only source for emergencies, medical advice, legal advice, or safety-critical communication. Download Yap and carry a live AI interpreter in your pocket.

Clear water. Test your speaker. Verify the result. Crisp uses targeted sound frequencies to help eject trapped water and dislodge dust from iPhone and iPad speakers. Then it listens with the microphone to compare real Before/After dB measurements—so you can check the result instead of guessing. NO ADS. NO ACCOUNTS. 100% OFFLINE. Is my data private? Everything runs on your device. Nothing leaves your iPhone or iPad. No accounts, no analytics, no ads, no tracking. How do I get started? 1. Place your device face down on a soft surface 2. Set volume to maximum 3. Tap Start Eject and wait 3 minutes What can I do with it? - Eject trapped water using a 165Hz tone, or switch to Dust mode to shake out lint and debris - Choose Normal, Turbo, or Deep intensity for a faster or more thorough clean - Find your phone's exact speaker resonance point with Resonance Finder for a stronger clean - Compare a real Before/After dB reading, not just a guess, to confirm the cycle worked - Generate any tone from 20Hz to 22kHz — up to 30kHz in Ultrasonic mode — with sine, square, triangle, or sawtooth waveforms - Test speaker frequency response with bass (80Hz), mid (1kHz), and treble (8kHz) presets - Run stereo balance (left/right) tests on stereo-capable devices - Check your microphone for blockages with a one-tap diagnostic - Measure ambient sound level with the built-in dB meter - Sweep frequencies automatically to dislodge stubborn dust particles - Take a structured hearing test across the audible range and save your audiogram - Save your favorite frequencies for one-tap recall - Set a cleaning reminder and track your streak over the past 7 days - Ask Siri to eject water, hands-free - 100% no ads, ever — most speaker-cleaning apps are free with ads until you subscribe; Crisp never shows one What devices does it work on? iPhone or iPad running iOS 17 or later. The same audio principles work on any built-in speaker. Why use Crisp? Speaker grilles trap moisture from sweat, rain, pool splashes, and humidity. Dust and pocket lint accumulate over time. Crisp uses sound vibration — the same technique built into Apple Watch — to physically dislodge particles without opening your device or using cleaning tools that can damage internal components. Does it really work? Sound vibration ejection is a well-documented technique. Results depend on how much water is trapped and how recently. For best results, run the cycle within an hour of water exposure, repeat 2 to 3 times, and keep the device face down throughout. How much does it cost? Download free. Optional Crisp Pro plans and any eligible introductory offer are shown in the app using your local App Store price. You can manage or cancel subscriptions anytime in Settings.
