Echobell turns a webhook, an API call, or an email into a notification you can't miss — including a real phone call that rings through Silent Mode and Focus. HOW IT WORKS Create a channel, point any service at its trigger URL or email address, and pick how urgent it is: a normal push, a Time-Sensitive alert, or a phone call. FEATURES - Phone call alerts. An automated voice call reads the message aloud. It rings on your iPhone and natively on your Apple Watch, even when the app is closed. - Trigger from anywhere. Webhook, API, or a unique email address — Grafana, TradingView, IFTTT, Zapier, Home Assistant, or your own script. - Templates. Build the title and body from the payload your service sends. - Conditions. Notify only when it matters, like status == "error" or price > 50000. - Channels and subscriptions. Share a channel with your team; everyone picks their own urgency. - Direct keys. Fire a one-off alert without setting up a channel. WHO IT'S FOR On-call developers watching servers, deploys, and CI. Traders following price and strategy alerts. Anyone who needs a specific email or smart-home event to actually reach them. Premium unlocks phone call notifications, unlimited channels, and unlimited direct keys.
