Vesper Sky is an editorial iOS weather app that replaces the standard grid of numbers with a sentence about the sky — the kind a thoughtful friend would write after stepping outside.
It is the work of iSimplifyMe, an independent studio in Chicago with over 15 years of design and product work behind it. The thesis is simple: weather writing is the product; weather data is the raw material.
The app is organized around five surfaces.
The Today tab leads with the editorial brief — two to three sentences written to be read in under ten seconds.
The Sky tab overlays live radar on a custom dark map with a plain-language editorial card explaining what the atmosphere is doing.
The What to Wear surface presents three silhouettes with biometric-accurate outfit recommendations, each fabric chosen for the day's actual feels-like, humidity, and wind.
The Sunset Verify feature predicts sunset quality on a 0–100 scale from live atmospheric data, then lets users rate the sky they actually saw — building a personal accuracy track record over time.
The Journal stores every rated sunset, every outfit, and every brief that meant something, saved locally and never uploaded.
The platform work is unusually deep for an indie launch. Seven widget kinds ship across every Home Screen size, with configurable widgets through App Intents. Live Activities and Dynamic Island support countdown through golden hour on supported devices. All six Apple Watch complication surfaces are implemented with native SwiftUI. WeatherKit powers the underlying forecast data, routed through the right system APIs throughout.
Vesper Sky is a paid iOS app with a 3-day free trial on monthly ($2.99) and annual ($24.99) subscriptions, or a one-time $59.99 lifetime purchase. It launches on the iOS App Store on May 12, 2026.
