Did your phone get wet, or is your speaker sound muffled? Speaker Cleaner pushes trapped water and dust out of the speaker grille with sound waves — then the speaker test lets you hear the result yourself. HOW IT WORKS The app plays sound in pulses. Each pulse drives the speaker diaphragm outward and ejects water, while the short silence between pulses stops the water from being pulled back in. A steady tone can't do that — it sucks the water back. THE CLEANING PROGRAM (4 STAGES) - Pulsed Water Ejection: Short bursts of sound push water out of the grille. - Resonance Sweep: Scans the frequency band where your speaker vibrates most, loosening stubborn droplets. - Vibration: Shakes the phone to dislodge whatever is left. - Waveform Tour: A final pass through four different waveforms. FEATURES - Full Clean: Bottom speaker, earpiece, or both — pick what you want to clean. - Speaker Test: Play each speaker separately and hear which one has a problem. - Stereo Sound Test: Check left-right balance. - Manual Mode: Generate a continuous tone at any frequency, with 4 waveforms and amplitude control. - Decibel Meter: Measure ambient noise in real time — live dB readout, average/min/max and history. Measure the before/after difference. - Safe to Use: Automatic cycle limits and cooldown periods protect your speaker. - Step-by-Step Guidance: Speaker selection, volume check and a phone-position guide. SUBSCRIPTION INFO - A subscription is required to use the cleaning and test features. - Start with a 3-day free trial. - Payment is charged to your Apple account when the free trial ends. - The subscription auto-renews unless canceled at least 24 hours before the end of the current period. - Manage or cancel anytime in Settings > Apple ID > Subscriptions.

OtoKarnem keeps your car's whole record in one place. Log your mileage, fuel, service and expenses; OtoKarnem remembers your insurance and inspection dates for you. REMINDERS • Get notified before your traffic insurance, comprehensive cover (kasko) or vehicle inspection expires. • Haven't logged your mileage in a while? You'll get a short reminder, at most four times, never pushy. • Every notification stays in the Notifications screen; swipe to mark it as read or delete it. RECORDS AND EXPENSES • Mileage history: see how far your car has gone. • Fuel log: litres, price per litre and station. • Service and maintenance log: when, at what mileage and what was done. • Expense summary: a monthly chart of fuel, service, insurance and other costs; share the report with one tap. YOUR DOCUMENTS, ALWAYS WITH YOU Add photos or PDFs of your registration, policies and other papers to your car. Open them on your phone whenever you need them, and share them if you have to. ACCIDENT REPORT Fill in the accident report step by step on your phone. Party details, accident location and damage photos all in one place. Draw the sketch by dragging and dropping ready-made roads, junctions and vehicles, or draw it freehand. PARKING AND STATIONS • Save where you parked with its location, a note and a photo. No account needed. • See fuel stations and EV charging points near you on the map. SHARE YOUR CAR Keep track of the same car with your partner or family. The owner creates an invite code, and whoever enters it sees the car in their own list. People you share with can add and edit records and get the reminders too. Only the owner can mark the car as sold or remove people. WHEN YOU SELL YOUR CAR Mark the car as sold. When the new owner adds it, they take it over with its mileage, service and inspection history. Your fuel, insurance and kasko records, documents and photos are not shown to the new owner. The same car can't be added to two accounts: if someone tries to add it before the owner marks it as sold, the owner is asked to approve. WARNING LIGHTS GUIDE What does that dashboard light mean? Step-by-step guidance for oil pressure, overheating, brakes, the check engine light, ABS, tyre pressure, glow plugs and more. Each light is marked "Stop now", "Get it checked" or "Info", and the guide works offline. MORE THAN ONE CAR Add all your cars. Each car keeps its own records, documents and reminders. PRIVACY • Your records are tied to your account, so they stay with you when you change phones. • Your location is used only while you use the app, for parking, the accident address and nearby stations. • You can delete your account from the profile screen at any time, and your personal details are deleted. Cars you share pass to the people you share them with. For your other cars, the mileage, service and inspection history stays with the car and may be passed to a future owner who adds it. • The app shows ads. Note: the app interface is currently in Turkish.

Verdict
The clearest difference is in-app purchases: OtoKarnem at none against Speaker Cleaner's 5. OtoKarnem also leads on device support (3 vs 1) and iOS requirement (15.1 vs 17.0). Speaker Cleaner's advantage is ads (none vs shown). On price and update cadence there is nothing between them.
