Attachments Attach a photo, PDF, audio or video when you answer an alert, or paste a link to one, if the file is already somewhere. Whoever sends an alert can ask for a note, a file, or both before a particular answer can be given — and each answer asks only for what it needs. Attachments are shown in the alert, not listed. Images appear inline; swipe between them when there is more than one. Alerts that escalate An escalating alert has its own sound, so you can tell a new alert from one nobody has answered yet. It replaces the earlier notification for the same alert instead of adding another to the tray. Sending Set up M91 with a coding agent: copy one prompt, paste it in. The send link and cURL are under "Setup manually". Links in an alert's title or description are tappable. Pick a country code from a list when adding people. Fixes Alerts sent without response options now ring, instead of arriving as a quiet notice. Opening an alert stops the escalation calls. The same alert no longer arrives twice when you open the app. A settled alert's notification clears instead of staying in the tray. Dismissing one alert's notification no longer clears others. Buttons at the bottom of a screen were sitting under the system navigation bar and couldn't be pressed. The keyboard no longer covers what you're typing.

M91 now works around channels — a group of people alerted together. • Sign in with your phone number, nothing else to set up • Create a channel, invite people, get a link that alerts all of them • Paste that link into anything that can call a URL — no code • Send a test alert with one tap and watch your phone ring • Give someone else permission to send; they get their own link

M91 is now built around channels. A channel is a group of people who get alerted together. Create one, invite people by phone number, and you get a link that alerts everyone in it. No account setup, no API keys, no integration work — paste the link anywhere that can call a URL. • Sign in with your phone number. Nothing else to set up. • Create a channel for anything you need watched, and invite the people who should be woken. • Each channel has its own alert link. Open it in a browser, put it in a cron job, a monitoring tool, or a spreadsheet — anything with a "URL to call" field. • Give someone else permission to send. They're invited, they accept, and they get their own link. • Send a test alert with one tap and watch your phone ring before you wire anything up. Fixes • Alerts sent without response options now play the M91 alert sound instead of the default notification sound. • Tapping an alert notification now opens the alert, including when the app was closed or in the background. • You no longer get an escalation phone call for an alert your phone already received. • Channel names, member counts and the send controls no longer flicker while a channel loads. • Searching no longer leaves you on a screen with no way to clear it.

A fresh look for M91. • New app icon — the M91 mark, now matching the design used inside the app • Refreshed launch screen with proper light and dark versions

A redesigned M91, and no more calls for alerts you've already seen. Critical alerts used to ring your phone even when the notification had already arrived. That's gone. Alerts you respond to or close now clear from your notifications straight away. NEW LOOK Every screen has been rebuilt. Alerts are easier to scan, severity is clearer at a glance, and a critical alert shows you how long until it calls the team. FINDING ALERTS • Search across every alert • Filter by organisation, urgency, or a date range • Filters now apply when you tap Apply, so you can set several at once ALERT DETAIL A single activity log showing what happened and when — who was notified, who answered, who closed it. Long descriptions collapse so the important parts stay visible. Sharing an alert now includes the full detail in plain text.

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

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

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.

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.
