ChronoWeather — Support

ChronoWeather shows you the weather along your driving route at the exact time you will be at each point. Enter an origin, destination, and departure time, and the app colors your route in real time — green for clear, yellow through red for increasing rain, blue for snow, purple for sleet. Scrub the timeline to fly through your journey hour by hour and see conditions update at every mile.

Features

• Color-coded route map — Each segment of your drive is colored by precipitation type and intensity using Apple WeatherKit hourly data.
• Timeline scrubber — Drag the slider to move through your journey and see the weather card update in real time. The slider color matches the weather at your current position.
• Forecast by Location — A city-by-city breakdown shows temperature ranges and conditions at each town along the route. Tap any city's date to shift your arrival time; the change cascades to every later stop automatically.
• Departure picker — Change your departure time at any point and the entire forecast recalculates.
• Wind arrows and temperature labels — Overlaid on the map along the route.
• ChronoWeather Pro — Extends the forecast window from 2 days to 10 days, and unlocks Saved Favorites and Journey History. One-time purchase, no subscription.

Frequently Asked Questions

How do I plan a route?

Tap the search bar at the top of the screen. Enter your starting point in the From field and your destination in the To field. Use the Departing picker to set your departure date and time, then tap Go.

Can I use my current location as the starting point?

Yes. Tap the blue location icon to the right of the From field. If prompted, allow location access. The app uses your location only to populate the origin field — it is never stored or transmitted.

Why does the forecast show question marks or gray segments?

Gray or dashed segments mean the forecast data for that part of your route falls outside the forecast window. The free version covers 48 hours from your departure time. If your route extends beyond that, those segments will appear as unknown. Upgrade to ChronoWeather Pro to extend the window to 10 days.

Some segments show an exclamation mark. What does that mean?

An exclamation mark means the weather fetch for that segment failed, usually due to a network error. Tap the icon to retry all failed segments.

How do I change the arrival date for a specific city?

Expand the Forecast by Location section at the bottom of the screen. Tap the date shown below any city name and choose a new date from the menu. The change will cascade forward to every city after it on the route.

How do I shift the entire departure time?

Expand Forecast by Location and use the Departs picker at the top of that section.

What does ChronoWeather Pro include?

Pro extends the forecast window from 2 days to 10 days, adds Saved Favorites (name and save your most-traveled routes for one-tap replay), and adds Journey History (automatically keeps your last 10 routes). Pro is a one-time purchase with no subscription.

How do I restore a previous Pro purchase?

Tap the three-dot menu in the top right, then tap Upgrade to Pro. On the upgrade screen, tap Restore Previous Purchase. Your purchase will be verified through your Apple ID.

Is my data sent to any server?

No. All data — saved routes, journey history, preferences — is stored locally on your device using iOS. Weather data is fetched directly from Apple WeatherKit. Nothing is sent to any third-party server.

Why does the route weather take a moment to load?

ChronoWeather fetches individual hourly forecasts for each point along your route from Apple WeatherKit. Depending on the length of your route and your connection speed, this typically takes 5–15 seconds. Segments color in progressively as each fetch completes.

Does the app work without an internet connection?

An internet connection is required to fetch weather data and compute routes. Once loaded, the weather data is cached for 30 minutes, so brief connectivity interruptions during a session will not clear your forecast.
