Decibels vs Laundry Drying Time Calculator

Decibels is a sound level meter that remembers what you measured. Point it at the noise, press start, press stop — and the reading stays. Average (Leq), maximum, minimum, duration and the full level trace, saved automatically, every time. No account, no subscription, and nothing leaves your phone unless you send it. MEASURE • A-weighted (dBA) or unweighted, per IEC 61672 • Fast (125 ms) and Slow (1 s) time weighting • LCpeak for impulses — alarms, slams, machinery • Live level trace with a ten-second window • Calibration offset for matching a reference meter KEEP • Every measurement saved automatically • History with the full trace of each run • CSV export carrying the settings it was taken under Decibels stores your measurements on your device and nowhere else. It records no audio — only the level — and asks for no location, no account and no identifiers. A note on accuracy: a phone microphone is not a calibrated instrument. Decibels is honest about that. Use the calibration offset against a reference meter for absolute readings, and treat it as an excellent relative instrument otherwise.

How long will your laundry take to dry? DryTime estimates the minutes until a wet T-shirt, towel or other washing is dry — indoors, in the shade or in the sun — from the live temperature, humidity, wind and sunlight where you are. Splashed water on your shirt to cool off in the heat? DryTime estimates how many minutes until it dries — and how long that cooling effect lasts. Pour a cup over your head, soak a towel, wet your hair: enter how much water and where, pick cotton or synthetic, sun or shade, and DryTime does the evaporation math from the live temperature, humidity, wind and sunlight at your location. Indoors, in shade, or in front of a fan? Every reading auto-fills from the weather at your spot, and you can nudge any value by hand — then tap "reset to live" to snap back. Start a timer to watch the minutes tick down on your Lock Screen as a Live Activity. Estimates only, shown as a guide.
