Drying Day

Some days the clothesline does a full load in two hours. Some days everything hangs damp until dark, and some days the rain gets to your laundry before you do. Drying Day answers the only laundry question that matters, before you press start on the washer: is it worth hanging outside today? A verdict, not a weather chart No radar to squint at, no humidity graphs to interpret. One clear answer in plain words — great drying day, good day to line-dry, drying will be slow, risky with a chance of rain, or better dry indoors — with the reason in one warm sentence underneath. What you get • An estimated drying window for today, with suggested times to hang out and bring in: "9 am – 3:30 pm." • How fast the line will work — roughly when a full load should be dry. • A suggested bring-in time, and why: forecast rain, or dusk. • The next three days as laundry advice, with the best laundry day tagged — so "do a load today or Saturday?" takes one glance. • Quiet, useful alerts (all optional): a heads-up the evening before a good drying day, a nudge when the window opens, and a reminder to bring the laundry in before forecast rain. • A "play it safe with rain" switch for people who'd rather rewash nothing, ever. • Wind in mph, humidity as a percentage, times that follow your clock setting. • A last-checked note when you're offline, so you always know how fresh the advice is. Honest about forecasts A forecast is a guess, and Drying Day says so. It hedges where hedging is honest, tells you the main risk out loud, and leaves the final call where it belongs — with the sky over your own clothesline. Built for people who line-dry Whether it's a backyard clothesline, a retractable line on the porch, a rack on the balcony, or a drying rack by the window on the days the sky says no — if you hang laundry to dry, this is for you. Made in Australia, where a good drying day is a genuine household event, and it works anywhere in the world there's weather and wet laundry. Quietly respectful No accounts, no tracking, no laundry log. Your location is used to fetch the forecast and show your area’s name, and we run no servers of our own — the privacy policy explains the rest, including the single ad. Free with a single unobtrusive banner; one small one-time purchase removes it forever. No subscriptions, ever. Weather data by WeatherAPI.com. Drying Day is an informational tool — it reads forecasts, it doesn't control clouds.

Verdict
The clearest difference is in-app purchases: 知雨天气 at none against Drying Day's 1. 知雨天气 also leads on ads (none vs shown). Drying Day's advantage is update cadence (fortnightly vs every 5 weeks) and device support (3 vs 1). On price there is nothing between them.
