On-call alerts for one person
Most on-call tools are built for a team: a rota, schedules, escalation policies, and a price per seat. If you are the only person who gets woken — a solo founder, a freelancer looking after a client's servers, the one engineer at a small company — you pay for all of that and use none of it.
Call Me If is on-call for one person.
The whole setup is a sentence
"Ring, then call me if the checkout API goes down."
You write it in the app and choose what it does:
- Notify, never silence — a notification Do Not Disturb cannot mute.
- Ring — full screen and an alarm sound, once.
- Ring, then call me — rings, rings again two minutes later, then phones your own number, then reaches your backup person.
You acknowledge once, on the phone or by pressing 1 on the call, and everything stops.
Where alerts come from
Anything that can send an HTTP POST with a key: Grafana,
UptimeRobot, a cron job, a script, curl. Each source gets its own key,
and replacing a leaked key never breaks the sentence behind it.
The backup person
The one thing a team gives you that a single person lacks is somebody else. On Pro you can add up to three backup people. Each one is invited, agrees, and is only reached after you have not answered — and the app always says truthfully whether anybody is covering you.
It tells you when it fails
Your phone checks in every fifteen minutes. When it goes quiet we say so, and what probably caused it — usually a battery setting the phone's maker turned back on after an update. No alerting product reaches a hundred percent; the useful thing is knowing before the night that matters.
What it does not do
- No rotas or hand-offs. When you grow into a team that shares a pager, a team product fits better.
- Android only.
Three sentences are free, forever, with no card — enough to put it behind the alert you care about most. See pricing.
Call Me If is not for medical, emergency or life-safety use.
