Polar is having a major outage
Check the number of user-reported issues over the past 24 hours, grouped into 20-minute intervals. It's normal to see occasional reports, which may be due to individual user issues rather than a broader problem. We only consider an issue widespread if there are multiple reports within a short timeframe.
 
    IsDown has tracked 118 incidents since started monitoring Polar status in February 2021. We collect data from 4522+ services, and normalize the data to give you a clear picture of the impact of the outage. It will show official Polar outages and also issues that we're started by a spike in crowdsource reports.

Users are monitoring tens of services with IsDown. Here are some that are monitored together with Polar. With IsDown you can get a bird's eye view of all your dependencies and how they are performing.
Polar offers a suite of fitness tracking and management tools, including mobile applications, web services, and APIs for syncing with third-party devices.
Monitoring Polar since February 2021
Tracking 16 Polar services and regions
12 incidents in 2025
IsDown is a status page aggregator that monitors if Polar and all your dependencies are experiencing issues. We combine the status of all the services you dependent and provide a clear view of all your vendors health in one place. We not only monitor official information but also crowdsourced reports. That means that even when Polar, per example, doesn't report an outage, you will still be notified if other users are experiencing issues.
Every few minutes we go to the status page of Polar (and 4,522+ other services) and check if they are experiencing issues. We collect the status and outage information of Polar's 16 components. Also, we not only monitor official sources but also user reports. Sometimes or a lot of times vendors take some time to report an incident, so by monitoring user reports we're able to alert you early.
Not only you will get notified, but IsDown offers notification filters, so you can choose which issues you want to be notified about. This way you avoid getting all the incidents from Polar and other services.
 
            IsDown checks Polar official status page for major/minor outages or downtimes. A major outage is when Polar experiences a critical issue that severely affects one or more services/regions. A minor incident is when Polar experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a Polar outage, we send you an alert and update your dashboard and status page.
Polar and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.
IsDown collects all information from the outages published in Polar status page to provide the context of the outage. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.
Polar publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.
IsDown monitors Polar and all their 16 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.
Our tool was build to be the best way to monitor all your external dependencies in one place. IsDown not only will help you monitor Polar but also 4,522 other services. Your team and customers will have a clear view of all your dependencies and their status, making it easier to identify and resolve issues.
Add all your dependencies to your dashboard. IsDown will monitor them in real-time and send you alerts when there is an issue. You can also create a status page for a bird-eye view and share it with your team.

Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.
IsDown and DownDetector help users determine if Polar is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information instead of just relying on reports from users. The integration allows us to provide more details about Polar's Outages, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.
