Polar Flow is down in a widespread outage affecting the mobile app, web service and third-party syncing. Polar has confirmed the disruption and says that user data remains safe.
Is Polar Flow down?
Yes. Polar confirmed the outage through its official service status page at 08:17 UTC on July 16, 2026.
The company says all of its online services are down while its technical team investigates the problem. It has not disclosed the cause or provided an estimated restoration time. Polar.com, the company’s support website and its online store continue to operate normally.
The outage appears to be on Polar’s side rather than a problem with an individual phone, watch or internet connection. Reinstalling the Flow app or repeatedly trying to pair a watch is therefore not going to fix it.
Polar Flow acts as the main hub for most Polar devices. It stores training sessions, activity data, sleep information and recovery insights. The company has been working through a wider Flow app and web overhaul, so changes to the software are incoming.
Which Polar services are affected?
Polar lists major outages for the Flow mobile application and Flow web service. Polar Beat is also down, along with Polar accounts, Polar Club, Team Pro and GoFit.
The disruption extends beyond Polar’s own apps. Its API and third-party syncing service are marked as suffering a major outage. This prevents data transfers to Strava, TrainingPeaks, komoot, Nike and MyFitnessPal.
Users may see failed login attempts, empty or outdated dashboards, workouts stuck on a watch or sessions that appear in Flow but not in a connected service. These symptoms all fit the current outage.
Is Polar workout data safe?
Polar says all data is safe. There is currently no indication that stored account information or previous training history has been lost.
A workout recorded on a Polar watch will normally remain on the device until it can transfer to Flow. Users should leave the session in place and wait for Polar to restore its services. Removing the watch from the app, deleting the app or carrying out a factory reset could create extra work without addressing the server problem.
Workouts waiting for Strava or another connected platform may transfer automatically once Polar restores the API. Polar has not confirmed how it will handle the backlog, so it is worth checking for duplicate or missing activities after the outage ends.
When will Polar Flow work again?
Polar has not given an estimated time for restoring Flow or its connected services. Users can follow the latest updates on Polar’s official status page.
The disruption follows yesterday’s Google Health outage, which prevented Fitbit devices from syncing and pairing for several hours. Polar users can continue recording workouts on their watches, but syncing, account access and transfers to connected services may remain unavailable until the company restores its platform.
This article will be updated when Polar provides more information.
