## What is M91?

M91 is a real-time incident management app built for on-call teams, DevOps engineers, and SREs. Get instantly alerted when critical incidents occur, take ownership, and resolve issues — all from your phone.

REAL-TIME INCIDENT ALERTS
Receive high-priority push notifications the moment a critical incident is triggered. Alerts come through even when your app is in the background or closed, so you never miss an outage.

ONE-TAP ASSIGNMENT
Assign incidents to yourself directly from the push notification or the incident detail screen. No need to open a laptop or switch contexts — respond in seconds.

FULL INCIDENT LIFECYCLE
Track every incident from triggered → acknowledged → assigned → resolved. See who's handling what, when it was accepted, and when it was closed.

SMART ESCALATION
If a push notification isn't acknowledged in time, the system automatically escalates via voice call. This ensures someone on your team always responds to critical issues.

SEVERITY-BASED PRIORITIZATION
Every incident is tagged with a severity level — Critical, High, Medium, or Low — so your team can focus on what matters most and triage effectively.

RESOLVER GROUPS
See all team members assigned to each incident. Know exactly who's in the resolver group and coordinate your response.

DETAILED INCIDENT VIEW
Get full context at a glance: source, category, description, owner, timestamps, assignment history, and resolver group — everything you need to understand and act on an incident.

SHARE INCIDENTS
Quickly share a formatted incident summary with your team via WhatsApp, Slack, email, or any messaging app.

OFFLINE SUPPORT
Queue actions like assign and resolve even when you're offline. They automatically sync when connectivity is restored, so you're never blocked.

SECURE AUTHENTICATION
OTP-based phone login with automatic token refresh keeps your session secure and persistent. No passwords to remember.

Whether you're managing production systems, monitoring infrastructure, or running an on-call rotation, M91 keeps your team responsive and your systems reliable.

Built for teams that can't afford downtime.


## Version history (last 5 releases)

### 1.2.1 — 2026-08-26

• No more phone calls for alerts you've already seen.
• Search your alerts, and filter by how urgent they are.
• Long lists load faster.

### 1.2.0 — 2026-08-14

Respond your way
Alerts now carry the response options chosen by whoever sent them. Take an alert on
behalf of everyone so the rest of the team stands down, or answer just for yourself
without silencing anyone else.

Decide who can alert you
Organisations now have to ask before they can reach you. Accept or decline from
Invitations, and change your mind at any time from Organisations.

A clearer alert screen
The response someone took is now front and centre, with who took it and when.
Recipients are easier to scan at any size, whether an alert went to three people
or three hundred.

Also in this release
- A new alert sound
- Fixed alerts that could not be closed
- Fixed duplicate screens when opening an alert from a notification
- Fixed a startup loop that could leave the app stuck loading

### 1.1.1 — 2026-08-05

Faster sign-in
When you're on mobile data, we can now confirm your number with your mobile
network in the background — so you often won't need to type a code at all.
If that isn't available, we'll text you an OTP as usual.

### 1.1.0 — 2026-08-01

Sign-in has changed. M91 now uses a one-time code sent to your phone instead of a password. If you're already signed in you'll stay signed in — no action needed.

Alerts now reach you on iOS even when the app is fully closed. Previously an alert could be missed if M91 wasn't running in the background. Alerts also arrive with a distinct alert tone so they're never mistaken for an ordinary notification, and break through Focus modes.

Assign straight from the notification on iOS. Take ownership of an incident without opening the app.

Android lock screen improvements. An incoming alert now wakes the screen and shows the full incident on the lock screen, instead of forcing the app open over it. The alert tone repeats so it's harder to sleep through.

Fixed: an expired session showed an error screen instead of returning you to sign-in.

### 1.0.2 — 2026-05-17

UI changes and bug fixes
