COROS June 2026 update: heart rate recovery, battery health page, and AllTrails integration
COROS’s June 2026 app and firmware update adds airplane mode and rock climbing route detection. Still, three of the features stand out: heart rate recovery between intervals, a battery health page, and a direct connection to AllTrails.
Heart rate recovery
How quickly your heart rate drops after hard exercise is a useful indicator of fitness, but perhaps sometimes difficult to meaningfully record as the end of the material parts of the workout is not always entirely clear, e.g. do you include the run home before measuring the recovery heart rate? A faster recovery generally means your body is coping well with training load. COROS now measures this automatically.
After any tracked activity, the watch records how far your heart rate drops over the next two minutes after you stop. For interval sessions, it also logs recovery between each rest period and adds it to the lap table, so you can see how your recovery changed across a session.
COROS says future updates will add more to this, and there is perhaps some scope for interesting insights between reps. For now, the per-interval data in the lap table is the most useful part: you can see whether your recovery got slower as the session went on, which is harder to spot from a post-session summary alone.
Garmin has tracked heart rate recovery for some time as part of its training readiness scoring. COROS is late to the feature, but the interval-level detail in the lap table is a practical addition. The feature is available on PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S.
Battery health page
Watch batteries degrade over time, and until now, COROS users had no way to see how their batteries were holding up or whether something was draining them faster than expected.
The new Battery Health page shows power use and daily usage trends over the past seven days. More usefully, the watch now monitors its own battery in the background and shows a warning banner if it detects anything unusual, rather than leaving you to wonder why your battery is running low faster than it used to.
This is available on PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S.
AllTrails integration
AllTrails is the most widely used route app for hikers and trail runners. The new integration connects it to COROS in both directions: routes sync from AllTrails to your watch for navigation, and completed activities automatically upload back to AllTrails. If you use AllTrails to find routes and then run or hike them on a COROS watch, the two now communicate without any manual steps.
There is one thing to be clear about: direct route sync requires an AllTrails Plus or Peak membership. Plus costs around $36 per year, and Peak costs around $80 per year. Free AllTrails users can still get routes onto the watch by exporting a GPX file and importing it through the COROS app, which was already possible before this update.
Unlike the other two features above, AllTrails integration lands on every current COROS device, including older models such as the PACE 2, APEX Pro, VERTIX 1, APEX 42/46mm, and the DURA bike computer. It is the broadest feature in the June update. For more on using your COROS watch for hiking and trails, see the hiking technology guide.
Which devices get what

The update is rolling out through the iOS and Android app stores. Once the app is updated, a firmware update will appear for the watch to activate the new features. COROS expects global availability within one week of the 24 June release date.
Quick answers
Which COROS watches get heart rate recovery in the June 2026 update?
PACE 4, PACE Pro, PACE 3, APEX 4, APEX 2, APEX 2 Pro, NOMAD, VERTIX 2, and VERTIX 2S. The DURA, PACE 2, APEX Pro, VERTIX 1, and APEX 42/46mm do not get this feature.
Do you need a paid AllTrails subscription to use the COROS integration?
Direct route sync requires AllTrails Plus (around $36/year) or Peak (around $80/year). Free AllTrails members can still get routes onto the watch by exporting a GPX file and importing it through the COROS app.
What does the COROS battery health page show?
It shows your power use and daily usage trends over the past seven days. The watch also monitors its battery in the background and shows a warning if it detects unusual drain.
