Nimbus turns 47 weather models into one honest answer for your day. Loved by 412k commuters and 1.4M weekend planners.
No vibes. No 'partly cloudy.' Times, percentages, action.
Not 'partly cloudy.' Nimbus tells you to leave by 17:24 because rain at 18:08 is a 78% bet.
ECMWF, GFS, HRRR, and ICON blended at 1km. 47.2% more accurate than your default app.
Lightning within 12 km, hail within 28 km. We notify before the sky tells you.
Pick a window. Nimbus tells you the best 4-hour stretch this week. 1.4M weekend plans saved.
An app for people who actually need to plan around weather.

A weather app that finishes the sentence.

Pro pays for itself in one avoided soaking.
We blend 47 weather models, weighted by recent local performance. Average 24-hour MAE on temperature is 1.4°F; precipitation skill score 94.6 of MOS baseline.
1km grid resolution. Your park can have a different forecast from the road outside it. Useful when a thunderstorm is 4 km wide.
By default, only severe weather (lightning, hail, flash flood) within your radius. You can dial in custom rules — 'tell me when chance of rain in next hour > 47%' — without leaving the app.
Only when you check the app. If you opt into commute alerts, location is used briefly at your set times — never continuously, never sold.
Releases roughly monthly. Driven by storm season requests.
