Store screenshots supplied by the developer.
Optimized for iPhone Duo. Built with the latest SDK, the app fills the entire inner display and automatically adjusts its layout whether the device is folded or open.
Lumi Weather tells you in one glance whether now is a good time to go outside, what to wear, and whether you need an umbrella or sunscreen.
Instead of reading temperature, UV, rain chance and wind one number at a time, you get an outing score from 0 to 100 and a short verdict, from a great day to go out to a day that is nicer spent indoors. Tap the score to see how feels-like temperature, UV, rain and wind each shaped it, so every answer is easy to understand and easy to check.
Plan your day around the weather

No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured

lumi-weatherWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
