Echobell

A push notification is easy to sleep through, and some alerts deserve a ringing phone. That's Echobell's pitch. You create a channel in the app, and it comes with two things: a webhook URL and a dedicated email address. Send a request to the URL, or forward an email to the address, and the alert lands on your phone as a normal push, a time-sensitive notification or a phone call.

The site's examples are the kind you'd expect from an on-call tool: a server outage, a failed CI build, an App Review status change, a trading alert. One of its guides covers phone call alerts from CloudWatch alarms without setting up Lambda or Twilio.

Alerts are organised into channels, and a channel can be shared. You send teammates a subscription link and they receive the same alerts, which makes it a light way to keep a small team informed.

Raw webhook payloads are rarely readable, so there's a template feature that turns them into a proper message using variables, expressions and conditions.

Getting started looks quick too. The App Store listing describes the 2.0 release as adding a guided start: you send yourself a test alert in one tap, then connect a webhook or an email address.

Echobell is on iOS, including iPad and Apple Watch, and on Android. The iPhone app requires iOS 17 or later. There's a free plan with core features, per the site. The paid plan is $1.99 a month, or $1.66 a month on the annual plan, and adds unlimited channels, unlimited subscriptions and phone call notifications. Both paid options show a Start Free Trial button, though the site doesn't state how long the trial lasts.

The App Store names the developer as Dippod LLC. According to the privacy policy, effective May 26, 2026, the service collects the webhook and email content you send to it, along with device names and push tokens, and it doesn't sell or transfer personal information for marketing or advertising. Bear that in mind before forwarding sensitive email into a channel.

The terms of service are less finished. They say the agreement is governed by the laws of "[Jurisdiction]" and that disputes go to "[Arbitration Organization]", placeholders that were never filled in. If you're the one who gets the call when a server goes down, the free plan is an easy place to send yourself a first test alert.
