Water test, speaker water eject, dB meter & device health check.
Did your phone take an unexpected dive? Check Water-Resistant helps you inspect your device after water exposure — quickly, clearly, and safely. WATER RESISTANCE CHECK Use your phone's built-in barometer to estimate seal integrity. A guided, step-by-step flow measures pressure changes when you press the screen and tells you whether the seal looks intact or may be compromised. CLEAN SPEAKER — WATER EJECT Play a precisely tuned low-frequency tone that vibrates trapped water out of the speaker grille. Choose from Basic, Deep, or Ultra presets, watch the live countdown, and stop instantly at any time. SOUND LEVEL METER A simple decibel meter in your pocket: estimated ambient noise in dB with a live chart plus min, average, and max stats. Handy after speaker cleaning or to check how loud a place really is. POCKET BAROMETER & ALTIMETER Watch live air pressure and track relative altitude changes — a real-time altimeter and barometer using your phone's pressure sensor. DEVICE DIAGNOSTICS & HEALTH SCORE A complete health check-up for your phone: touch screen coverage test, speaker tone test, battery info, sensors, microphone, vibration, flashlight, SIM card, and biometrics — each clearly labeled as measured or manual so you always know what was actually tested. Every checkup feeds a device health score with inspection history and optional reminders. TOUCH SCREEN TEST Drag your finger across a full-screen grid to find dead zones and check touch accuracy around every edge. HOME SCREEN WIDGET Live pressure reading and one-tap shortcuts to every tool, right on your home screen. IP RATING GUIDE Confused by IP67, IP68, or IPX8? Pick the two digits and instantly see plain-English explanations of dust and water protection levels (IEC 60529). WATER EMERGENCY FIRST-AID Dropped your phone in water right now? Follow a guided checklist — power off, dry, and eject water — in seconds, with no interruptions. HONEST RESULTS YOU CAN TRUST This app provides estimates based on your device's sensors — it is not a manufacturer or IP certification. Real device info (model, OS level, security patch) is read directly from the system, and every diagnostic is labeled honestly. Download Check Water-Resistant and know your phone better.
