REN can work partially with Suunto, but there are a few important limitations.
What works
If your Suunto workouts sync to Apple Health (HealthKit), REN can import those activities from HealthKit.
REN can currently import:
Distance
Time
What doesn’t work (yet)
REN cannot push workouts to your Suunto device.
REN currently does not import heart rate from Suunto via HealthKit.
Imported data is limited, so you’ll see average pace/tempo, but not heart-rate based metrics.
Still required: your feedback in the app
Even with an imported activity, REN still relies on you to log:
How the run felt
Your self-evaluation (RPE / session feedback)
This feedback is an important part of how REN adapts your training.
What’s next
We’re planning to add more device integrations in 2026, alongside Apple Watch and Garmin support.
