Viltri

The forecast follows your route.

Most weather apps answer “what’s it like here?” Viltri answers the question you actually have before a trip: is this a good window to go?

Sailors, pilots and climbers call it a weather window — the stretch of favourable conditions you plan a trip into. Viltri builds your itinerary, then puts real conditions against every stop and every leg of it, so the decision is in front of you instead of scattered across six forecast lookups.

What it does

Trips, not just locations

Multi-stop itineraries with dates. Each stop carries its own live forecast, and each leg between them gets a warning appropriate to how you’re travelling.

Five ways to travel

Flight, drive, walk, transit and cycle. A cycling leg is judged on wind and rain; a transit leg is judged on delay risk at the origin. They are not the same question.

Advice for what you’re doing

Motorcycling, golf, boating or hiking. Each has its own thresholds — open water gets unsafe well before the same wind feels bad on land.

Severe alerts that say something

Official National Weather Service alerts for home, every trip stop and any place you’re watching — with real expiry timing, and no invented urgency.

Animated radar

A real precipitation timeline you can scrub through, covering recent history and the near-term nowcast.

Share with anyone

Send a trip to someone on Android, on a desktop, with no app and no account. The whole itinerary travels inside the link — it never touches a server.

A shared trip link won’t open

The trip is stored in the part of the link after the #. Some messaging apps trim long links when they preview them. If a link arrives broken, send it again as plain text, or paste it directly into a browser’s address bar.

My trips aren’t syncing between devices

Syncing uses iCloud, so both devices need to be signed into the same iCloud account with iCloud Drive turned on. Trips are stored on the device first, so nothing is lost while sync is off — turning it on brings them together.

Alerts aren’t arriving

Check that notifications are enabled for Viltri in the iOS Settings app, and that alerts are switched on in Viltri’s own Settings. Alerts come from the National Weather Service and only fire for genuinely new severe or extreme events — a quiet week is usually just a quiet week.

How do I cancel a subscription?

Subscriptions are billed by Apple, so cancelling happens in iOS Settings → tap your name → Subscriptions → Viltri. Cancelling stops the next renewal and you keep access until the current period ends. I can’t cancel or refund on your behalf — only Apple can.

What data does Viltri collect?

Less than you’d expect: there’s no Viltri server. Trips live on your device and optionally in your own iCloud. See the privacy policy for exactly what goes where.
