Weather forecasts beside sensor tiles on the open Duo
Does Weather Ultra work on iPhone Duo?
Yes, the developer says so: Weather Ultra adapts to both Duo displays, with forecasts beside sensor tiles when open and wide, and a full-width layout in portrait.
- App Store confirmedJonathan Clarke, the developer, on the app's product page and in its App Store release notes, which claim layouts for the Duo's closed and open displays. The notes for version 2.8 (released October 19, 2026) say the app is fully updated and optimized for iPhone Duo. The product page's picture shows an open, wide phone with forecasts beside sensor tiles and controls at the right edge.

Forecasts beside sensor tiles
Open and wide, the hourly forecast sits beside the weather sensor tiles, with controls along the right edge. Held upright, the layout runs the full width.
About Weather Ultra
Weather Ultra combines forecasts, weather-station readings and activity planning. The Now screen shows live conditions at a glance, the 10-day forecast has hourly and daily detail with sunrise, sunset and moon phase, and an on-device planner finds the best days for running, gardening or the beach. Davis WeatherLink users get real-time sensor data.
The developer shows a wide Duo layout with hourly forecasts beside sensor tiles, and describes a compact layout for the cover.
