Heii On-Call is $32 per month total for your team — not per user. https://heiioncall.com/ (Full disclosure: part of the team building it)
We use iOS “Critical Alerts” and similar on Android that breaks through any Do-Not-Disturb settings. https://heiioncall.com/blog/better-alerting-for-heii-on-call... Would you be willing to give that a shot? It wakes me every time :)
(It’s configurable too; we have vibrate-only or silenced modes. Think old-school beeper.)
In the rare case that it doesn’t wake you, we have configurable escalation strategies to alert someone else on your team after a configurable number of minutes.
I usually do not respond immediately to phone notifications, which I can handle async. Phone calls are by definition sync.
Heii On-Call will keep alerting you with these “Critical Alerts” until you’ve manually acknowledged. (Or until it escalates to a teammate and they acknowledge…)
And at least on my phone they sound nothing like normal phone notifications, which I personally always have on vibrate and/or DND anyway.
Give it a try and I think you’ll like it.
With SMS, Phone Calls and Critical Alerts / DnD override.
We're 5 USD/user.
We try to build as close to our users as possible. Happy for any new try outs! :)
