xWind is an easy to use tool to assist pilots in evaluating wind conditions with respect to head, cross and tailwind limitations. Once setup, the xWind app provides all information in one single screen, requiring minimal user interaction during high workload phases of flight, displaying: - Current wind direction and speed - Runway course - Cross and head or tailwind components - Currently applied wind limits - 'Forbidden' wind angles based on the current wind speed - Maximum wind speed table based on current wind limits Reference wind, runway course, as well as wind limits, can all be adjusted on the main screen by either dragging the wind arrow, course rose or wind limit lines. A settings button at the bottom presents a popup screen where both the units for wind speed (Kts or Mps) and the default values for wind limits can be specified. In addition to the general setting for wind speed units, the user can select the alternative units for only the current wind, wind components and maximum winds table by double tapping the wind display at the top of the main screen. When operating from a Kts country into Mps territory, this option allows to set the current wind and see the maximum allowed winds in Mps, based on limits that are still set in Kts. Or vice versa.... xWinds supports iOS darkmode.

Verdict
The clearest difference is update cadence: xWind at fortnightly against Zulu Time's every 3 months. xWind also leads on chart position (#195 vs unranked) and iOS requirement (12.0 vs 17.6). Zulu Time's advantage is rating (4.8 vs 4.6) and ratings volume (2.6K vs 554). On price, review sentiment, ads and in-app purchases there is nothing between them.
