TL;DR: Most wind apps notify you the same way Twitter does — and Twitter doesn’t wake you up when your phone is on silent. WindUp uses iOS time-sensitive critical alerts (and the Android equivalent) so the alarm rings even when your phone is on Do Not Disturb. You set the wind, we wake you up.
You set up your wind app. You picked your spot. You configured the threshold. You went to sleep. The wind blew at 7 AM, perfectly. You missed it.
This is the most common complaint riders have about every wind app on the market: the notification fired, but my phone was on silent. And so it didn’t ring. And so I missed the morning.
There’s a reason almost every wind app has this problem. There’s also a reason WindUp doesn’t.
Why your other wind app failed to wake you up
When a normal app sends you a notification — Instagram, Twitter, your weather app — iOS treats it as a standard interruption. That means:
- Do Not Disturb silences it. Set a sleep schedule? Notifications mute.
- Silent mode silences it. Phone face down with the switch flipped? No sound.
- Focus modes filter it. Personal/Work focus on? Almost everything muted.
This is by design. Apple doesn’t want every app to be a 3 AM alarm clock. The default experience is quiet.
For a wind alarm, that default is broken. The whole point is to wake you up at 6 AM when conditions hit. If your app inherits the same silencing rules as your group chat, it can’t do its job.
The two-tier notification system most apps don’t use
iOS has a separate, premium tier of notifications called time-sensitive notifications and critical alerts. These are reserved for things like:
- Medical alarms (insulin pumps, AED notifications).
- Public emergency systems (Amber Alerts).
- Real-time, time-bound events the user opted into.
When an app sends a time-sensitive or critical alert, iOS treats it differently. It can:
- Bypass Do Not Disturb.
- Bypass Silent mode (with the right entitlement).
- Cut through Focus modes you’ve set.
- Ring at full volume even when your phone is face-down.
It’s the layer between “regular notification” and “screaming alarm clock”. Used right, it’s the perfect fit for a live wind alarm.
Most wind apps don’t use this layer. They send standard notifications. So when you set them up before bed and your phone goes to silent at 11 PM, you don’t hear them at 7 AM.
How WindUp uses it (without being annoying)
We treat the wake-up alarm like the medical-grade tier it is. Here’s the rule:
- You decide which alarms are critical.
- You decide the time window.
- You decide the wind threshold and direction.
- We make sure that when those conditions hit, you wake up.
We’re conservative about it. The default for new alarms is a normal notification — not critical. You have to opt in. We ask you for permission once, you grant it, the alarm respects it.
That’s the difference. Other apps treat the alarm like a marketing push. We treat it like the reason you installed the app.
Real moments this solves
We hear these stories every week:
- “I set the alarm at 5 AM for the morning glass-off. My phone was on silent because my partner was asleep. The wind ramped up at 6:15 AM. I woke up at 9. The wind was gone by 8:30.”
- “I drove an hour to my home spot at 11 AM because the forecast looked good. The actual wind died by 10:30. The live station knew. My phone didn’t tell me.”
- “I missed three consecutive Saturdays of perfect kite conditions because Do Not Disturb silenced the alerts. I almost gave up the sport.”
Each of these is preventable. The wind was there. The phone knew. The notification just didn’t break through.
Setup, in 90 seconds
If you’ve been burned by a silenced alarm before, here’s how WindUp handles it:
- Open WindUp, pick your spot from any of 10,000+ live stations.
- Set your wind range — minimum, maximum, and direction filter.
- Set your time window (most riders use 6 AM–8 PM).
- Tap “Use critical alerts” in the alarm settings.
- Approve the iOS permission prompt — this is the one that lets us through Do Not Disturb.
- Sleep.
Done. We watch the station, you ride.

Why no other wind app does this
It’s not a technical mystery — Apple has documentation, the entitlement is available. The reason is mostly cultural: most wind apps are forecast tools first, alarm tools second. They built the alarm as a feature on top of a forecast app, and the forecast app’s notifications were never designed for wake-up.
WindUp is alarm-first. The forecast is a side dish. So we treat the notification stack like the main course.
The promise
Set an alarm at your spot. We’ll get through. You’ll never miss the wind again because your phone was on silent.
FAQ
The most common question: “Will it really ring at 6 AM when my phone is silent?” Yes — if you set the alarm window to include 6 AM and you’ve granted critical alert permission. That’s the entire deal.
