When something happens far from home, the first question is often the hardest: who do I call? The emergency number changes from country to country, and that is almost never the moment to find out by searching online. Global SOS exists so you never have to search. We have gathered the emergency contacts of countries around the world in one place, organized in a simple and direct way. In just a few seconds you can find the number for the police, the ambulance, the fire department, and the general emergency number for wherever you are. The idea is for the app to be useful exactly when every second counts. That is why the search is fast and the screen is clean, with no distractions. You open it, find the country, and the information is right there in front of you, no detours. Global SOS was designed for people on the move, whether for work, tourism, an exchange program, or the digital nomad life. It is worth a look before you board and, above all, the moment you arrive somewhere new. Knowing these numbers in advance brings a peace of mind that makes a difference for the entire trip. Keep in mind that Global SOS is a reference and lookup app. The numbers are provided for informational purposes and may change over time, so in a real emergency, always confirm the valid local number. The app is a support tool, not a substitute for the official guidance of each country's authorities. Download Global SOS and travel with greater peace of mind.
Water Eject & Clear Wave

Water trapped in your speaker makes everything sound wrong — muffled music, quiet calls, crackling audio. Water Eject pushes it out with sound, then proves it worked. HOW IT WORKS A precise low-frequency sweep moves your speaker's diaphragm, helping trapped water escape. We sweep 120–180 Hz instead of holding one fixed tone, because the most effective frequency varies between devices. Synced haptics add real physical vibration on top. WHAT MAKES THIS DIFFERENT Every other app plays a tone and leaves you guessing. We measure. Before you start, Water Eject plays a frequency sweep and listens with your microphone to read how your speaker is actually responding. After the session, it measures again — and shows you the change, with both response curves drawn on the same graph. You see exactly what came back. CLEANING MODES • Water Eject — sweeping low tone that pushes trapped water out • Dust Eject — rhythmic percussive bursts that shake loose dust and lint • AirPods Eject — clears the speakers on your connected AirPods • Deep Clean — a longer session across both speakers ALSO INCLUDED • Per-speaker results — find out whether it's the top or bottom speaker • Targeted ejection — clean only the speaker that needs it • Tilt coach — holds you at the right angle so gravity helps • Live output level so you know when it's too loud • Full history — track your speaker's clarity over time • Dry-check reminders, because water can take a while to fully clear • Offline emergency guide — what to do first when your phone gets wet AN HONEST NOTE Sound genuinely helps move water that's sitting in or near the speaker grille — the physics is real and the effect is measurable. But no app can reach water that has already got deeper into your device, and none can reverse corrosion. If a check shows no improvement across several sessions, the problem probably isn't water, and we'll tell you that instead of pretending otherwise. PRIVACY Your microphone is used only to measure your speaker. Audio is analysed on your device and is never recorded, saved, or sent anywhere. No account required. SUBSCRIPTION Water Eject is free to try. Pro offers a weekly auto-renewing plan and a one-time lifetime purchase; the exact price is shown in the app before you buy.

Verdict
The clearest difference is in-app purchases: SOS at none against Water Eject & Clear Wave's 2. SOS also leads on iOS requirement (17.0 vs 26.0). Water Eject & Clear Wave's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads and device support there is nothing between them.
