AerAlerts // Signal Operations
Choose from our live feeds: markets, crypto, quakes, storms, launches and more. Scroll down, tap the alerts you want, and activate. Safety alerts are free, most alerts are $1 a month, the bigger ones $2, and you can cancel any time. Alerts arrive through the free ntfy app on iPhone, Android or in your browser.
Tell us what to watch: a product back in stock, your team's final score, a permit filed on your street, a price crossing a line. We'll reply by email to say whether we can build it. If we can, it's a one-time $49 setup fee, then $25/month once it's running.
Tap any alert box to add it. Your monthly total updates as you go.
One monthly subscription covers your whole lineup, and you can cancel any time. Free alerts skip this step.
We email your private ntfy username, password and topic codes right away. They're also shown on screen after checkout.
Install the free ntfy app, sign in, and subscribe to your topics. That's the whole setup.
Tsunami warnings, extreme weather, full and new moons, and holiday and clock-change heads-ups are free forever. Just enter your email, no card needed.
Add every feed in a category and the pack price applies automatically. Add everything and you pay the All-Access price instead. Pack and All-Access subscribers get new feeds in their category at no extra cost when we launch them.
ntfy is a free, open-source push notification app for iPhone, Android and the web. AerAlerts runs its own private ntfy server, so only paying subscribers can read each feed.
No. Every alert a feed produces reaches you, and there's no daily limit on our server. Most feeds are tuned to fire only when something is actually notable.
Yes. Reply to your welcome email with what you want to add or drop, and we'll adjust your subscription. Self-serve changes are coming soon.
