How In-App Notifications Work in Ninety

Ninety's notification system keeps you informed about important updates across your Rocks, Milestones, To-Dos, and Issues. With the in-app notification feed and push notifications for web and mobile, you'll never miss critical assignments, comments, or @mentions from your team.

 

Ninety's notifications bell is on the top right of each page in the web platform. Click it to open up a list of your notifications.

 

 

Which Actions Trigger Notifications

Ninety automatically creates a notification for you when:

  • Someone assigns you a Rock, Milestone, To-Do, or Issue.
  • Someone comments on an item you own or follow.
  • Someone @mentions you in a comment thread on a Rock, To-Do, Issue, or Milestone.

 

How the Notification System Works

Ninety provides three primary ways to stay informed about your work:

  • In-App Notification Feed
  • Mobile Push Notifications
  • Web Push Notifications

Ninety's Web App Notification Feed

The notification feed is your centralized hub for all activity updates in Ninety. Access it by clicking the bell icon in the top navigation bar. The bell displays an indicator when you have unread notifications.

 

 

Accessing Your Notification Feed

To view your notification feed on the web app:

  1. Click the bell icon in the top navigation bar. The bell displays a red indicator when you have new notifications since your last time opening the feed.
  2. Review your notifications, they're organized by recent activity. The red indicator will clear automatically when you open the feed.
  3. Click any notification to open the item's detail panel and view the full context. Clicking a notification card marks it as read.
  4. Mark notifications as read or unread using the buttons on each notification card.

The notification feed displays activity across Rocks, Milestones, To-Dos, and Issues. Each notification includes the item name, who triggered the update, and when the activity occurred.

 
 

Push Notifications for Web and Mobile

Push notifications alert you instantly to assignments, comments, and @mentions, even when you're not actively using Ninety. These notifications work on both your web browser and mobile device. You can click or tap them to navigate directly to the relevant item, which will also mark the notification as read.

Both web and mobile notification channels are enabled by default for all users. You can disable either channel at any time without affecting the in-app notification feed.

 

Best Practices for Using Notifications

  • Reduce notification noise — Unfollow items that are no longer relevant to your work to keep your notification feed focused on what matters most.
  • Use @mentions strategically @Mention team members when you need their specific input or when you need their attention. Avoid overusing @mentions in comments intended for general awareness.
  • Check your feed daily — Make checking your notification feed part of your daily routine to stay aligned with your team and respond promptly to assignments and comments.
  • Customize delivery channels — If you prefer fewer interruptions during focused work, disable push notifications and rely on the in-app feed. If you need instant alerts, keep both web and mobile push notifications enabled.
  • Keep your browser updated — Ensure your browser of choice is kept up to date.

 

Understanding @Mentions

Type "@" in a comment or text field to open a list of contacts from your Directory in Ninety.

@Mentions allow you to bring specific team members into a conversation by tagging them in a comment. When you @mention someone, they receive a notification and are automatically added to the item's follower list.

Who Can @Mention Others:

  • Owners, Admins, and Coaches can @mention any active or invite-pending user on any item.
  • Managers and Managees can @mention any user who has access to the item.
  • Observers cannot @mention others or receive @mentions.

 

How to @Mention Someone:

  1. While writing a comment on a Rock, Milestone, To-Do, or Issue, type the @ symbol followed by the person's name.
  2. Select the user from the dropdown list that appears.
  3. Finish your comment and post it.

The mentioned user will receive a notification and will be able to follow the item's updates going forward.

 

@ mentions only works in comments, not in other text fields in Ninety.

 

 

Following and Unfollowing Items

Following an item means you'll receive notifications about comments and activity related to that item. You're automatically added as a follower when:

  • You're assigned as the owner of an item.
  • Someone @mentions you in a comment thread on a Rock, Issue, or Milestone.
  • You create the item.

To manually follow or unfollow an item:

  1. Open the item's detail panel (Rock, Milestone, To-Do, or Issue).
  2. Click the "Follow" or "Unfollow" button at the top of the panel.

Following items strategically help you stay informed about work that matters most while reducing notification noise.

 

Viewing Notifications on Mobile

While the in-app notification feed is currently available only on the web app, push notifications work seamlessly on both iOS and Android devices:

  1. Receive a push notification on your mobile device.
  2. Tap the notification to open Ninety's mobile app.
  3. The app navigates directly to the item's detail panel where you can view the update and take action.

Mobile push notifications keep you connected to your team's work even when you're away from your desk. Learn more about Ninety's mobile app.

 

Managing Mobile Notifications

To enable or disable mobile push notifications, you need to check two places:

  1. Device Settings: Ensure notifications are enabled (or disabled) for the Ninety app in your device's system settings.
  2. In-App Settings: Within the Ninety mobile app, navigate to Settings and toggle mobile push notifications on or off according to your preference.

Both settings must be enabled for you to receive mobile push notifications.

 

User Roles and Notification Permissions for Notifications

Different user roles have access to different notification features:

Role In-App Feed Push Notifications @Mention Eligibility
Owner Yes Yes Can mention any user on any item
Admin Yes Yes Can mention any user on any item
Coach Yes Yes Can mention any user on any item
Manager Yes Yes Can mention users with access to the item
Managee Yes Yes Can mention users with access to the item
Observer No No Cannot mention or be mentioned

Observers do not receive notifications or have access to the notification feed, as their role is designed for viewing-only access without active participation in work items. Learn more about user roles and permissions.

 

Troubleshooting Notifications

Not Receiving Push Notifications

  • Verify your browser or device allows notifications from Ninety.
  • Check your notification settings in Ninety to ensure the web or mobile channel is enabled.
  • On mobile, ensure you've granted notification permissions to the Ninety app in your device settings.

Missing Notifications in Your Feed

  • Confirm you're following the item. Notifications only appear for items you're following or when you're @mentioned.
  • Check if you have the appropriate user role. Observers do not receive notifications.

Too Many Notifications

  • Review the items you're following and unfollow those that are no longer relevant.
  • Adjust your email notification settings if you prefer to receive updates only through the in-app feed or push notifications.

Notifications stopped working

  • If you've recently cleared your browser data, switched browsers, or reinstalled your browser, your Ninety.io notification subscription has been reset. 
  • Visit app.ninety.io and opt back in to re-enable them.

Notifications not working

  • Disable browser extensions temporarily. Certain browser extensions can interfere with push notifications. 
  • Try disabling them for app.ninety.io to see if that resolves the issue.

Firewall preventing notifications

  • Check your VPN or firewall. Corporate VPNs or strict firewalls can sometimes block push notifications. 
  • Try disabling your VPN temporarily to test, or ask your IT team for assistance.

Never wanted browser notifications or already tried to deny browser notifications

  • We'll offer web push notifications up to three times. If you select “Not now” each time, we'll fully block these types of notifications in your browser after the third try.
  • If you block notifications via your browser settings (see above), we won't prompt you again.
