Important ECG App Note

Garmin says that moving forward, beta software for Venu 4/4S will have the ECG feature disabled. If you prefer to keep the ECG App accessible, Garmin recommends not participating in the Public Beta program.

Garmin also says the ECG App feature is expected to become available again in beta software toward the end of quarterly beta cycles, and it remains available with Live software updates on compatible watches.

Why This Update Matters

Major Voice and Training Additions

Venu 4 Beta 18.12 is more than a maintenance patch. Voice commands, a quick running workout, and XC Ski Indoor expand what the watch can do in daily fitness use.

Better Reliability Across Activities

The reset fixes cover strength workouts, golf, power-down behavior, Saved app usage, and software installation. Garmin also addresses workout flow issues such as suggested multisport workouts and structured repeat intervals.

ECG Tradeoff for Beta Users

The ECG note is important. Users who need the ECG App should consider staying on Live software instead of joining this beta branch.

How to Get the Update

To download Venu 4 Beta 18.12:

Open the Main menu
Go to Settings
Select System
Choose Software Update
Tap Check For Updates

Only watches enrolled in the Garmin Public Beta program will receive this beta.

Conclusion

Garmin Venu 4 Beta 18.12 is a substantial beta update with voice commands, new workout and activity options, and broad reliability fixes. The ECG App limitation is the key caveat for Venu 4/4S users considering this beta.
