Reful vs Hygrometer

Reful tells you what the wind is doing right where you're standing — in plain language, without the clutter. Open the app on the coast and you'll see the current wind speed, where it's coming from, and its name. A friendly compass points in the direction the wind is blowing, so you can feel what's around you at a glance. Reful is made for anyone who spends time by the sea — whether you're on the beach, at a café, walking the promenade, or just curious why your hat keeps flying off. WHAT YOU GET • Live wind conditions for your exact spot on the coast • Forecast for the days ahead, so you know what's coming • The names of local Adriatic winds — Bora, Sirocco, Maestrale and others — so you learn what's blowing and why • A simple scale that tells you when it's calm, breezy, or too windy to stay outside • Speed shown in whichever unit you prefer • Beautiful dark interface, easy on the eyes • Available in English, Croatian, Slovenian, Montenegrin, Italian, and Albanian BUILT WITH RESPECT FOR YOUR PRIVACY • No accounts, no ads, no tracking • Your location is used only to fetch the weather — nothing is stored on our side • No analytics, no data collection

Mold does not grow because a room is humid. It grows on the one surface that is colder than the rest — a corner, a window reveal, the wall behind a wardrobe. The air touching that surface can sit at 97% while the middle of the room reads a comfortable 55%. Hygrometer works out what is happening on that surface, and tells you the humidity to keep the room under. WATCH A ROOM • Add the cold surface you are worried about: a corner, a window reveal, an uninsulated wall, single or double glazing • See the humidity at that surface, not just in the room • Get the limit for the room, worked out from the surface temperature and the weather outside • That limit moves with the forecast — the same wall tolerates 73% on a mild day and 41% in a cold snap THREE WAYS TO GET THE NUMBERS • A HomeKit humidity sensor, read automatically — Eve Room, Aqara, SwitchBot, Netatmo and others • Typed in from your own hygrometer, whenever you check it • Or neither: Hygrometer estimates the likely range from the outdoor conditions and how the room is used, using the EN ISO 13788 humidity classes. Shown as a range, never as a measurement of your room WARNINGS THAT ARRIVE IN TIME • Mold risk when the surface reaches 80% humidity, which is long before anything looks wet • Condensation when the surface falls below the dew point • And before either: a colder forecast tonight pulls the limit down, so the warning comes before the surface turns, not after SHOULD YOU OPEN THE WINDOW? The answer relative humidity gets backwards. Airing out only dries a room when the outdoor air carries less water in absolute terms. In winter it nearly always does, even at 90% outside. On a warm humid day it often does not, and opening a cool room makes it damper. Hygrometer compares both sides in g/m³ and names the driest hour of the day. THE OUTDOOR INSTRUMENT • Outdoor relative humidity on a 0–100% analog dial with comfort bands • Dew point, absolute humidity in g/m³, mixing ratio, pressure and conditions • 24-hour humidity chart • Home Screen and Lock Screen widgets, which fetch their own reading rather than waiting for you to open the app ALSO • Follow your location, or search any city worldwide • °C / °F throughout • Eight languages • No account, no tracking, no ads Outdoor readings come from Apple Weather. Indoor readings come from your own sensor or from you — iPhone has no humidity sensor, and this app never pretends otherwise. Weather data provided by Apple Weather.
