About

Clearwhen

Features
Read full description

Weather apps answer the wrong question. "Rain today" — because of a 1 AM shower you'll sleep through. Clearwhen shows the weather for the parts of your day that actually matter. Set up your windows — Commute 7–9, Workday 9–5, Dog Walk at 6 — and get one honest answer per window, per day, across the whole week. • YOUR SCHEDULE, NOT THE CALENDAR'S — up to five custom time windows with names, icons, and per-weekday scheduling (no commute row on Saturday) • WORST-CASE WINS — if it rains at all during your commute, your commute shows rain. No averaging away the downpour. • TAP TO TRUST — any cell unfolds an hour-by-hour strip so you can see exactly when • A WEEK AT A GLANCE — 7 days across, your windows down, one bubbly icon per cell • HOME SCREEN WIDGET — today's windows without opening the app • YOUR PLACES — current location plus saved cities Free. No ads. No accounts. No tracking — your location never leaves your device except to fetch the forecast. Powered by Apple Weather with a National Weather Service fallback. Made with by Demers Design and Development.
