About this app

When paired with a compatible Garmin Varia radar device¹, the Varia app has the tools you need to ride with confidence. Using the Varia app, you can:
• Be alerted right on your phone when approaching vehicles are within 140 meters behind your bicycle.
• View color-coded alerts based on surrounding traffic: Green means you’re all clear, yellow means a vehicle is approaching and red means a vehicle is coming at you quickly and you should take caution.
• Receive tone and vibration alerts for approaching vehicles even when you’re not looking at your phone.

With a compatible Garmin Varia Radar Camera Tail Light or Garmin Varia Vue Camera Headlight, you can:
• Set the camera in the best position for capturing videos and photos.
• Record videos or take photos and save them while riding with a simple button press on your phone.
• Automatically record videos of incidents and save the video footage with the Incident Recording feature.

With a Varia Vue Camera Headlight, you can:
• Configure light mode configurations for your headlight.
• Add an optional Vault subscription, which automatically backs up your Varia Vue videos and provides easy access in the Varia app for searching, filtering and sharing.

By adding the Varia eRTL615 Radar Tail Light for eBikes, you can:
• Configure and edit light mode configurations for your tail light.

Easy to Use
Pairing your Garmin Varia devices with the app is quick and easy. Once you set them up, the Varia app will automatically recognize your devices.

Even if you already have a Varia device paired with a compatible Garmin device or head unit, the Varia app provides additional awareness and peace of mind while riding.

¹ Compatible devices are the Varia RearVue 820, Varia RVR315 Rearview Radar, Varia RTL515 Radar Tail Light, Varia RCT715 Radar Camera Tail Light, Varia eRTL615 Radar Tail Light for eBikes and Varia Vue Camera Headlight.

In the latest update, the horizontal line tracking approaching cars has disappeared. I have navigation via the Varia app turned on (as freeform window mode), so I used to always see cars on the sides. Now there are only car icons in the middle and I can't see them. It would help a lot if the Varia app itself supported freeform window mode in Android.

To give credit where credit is due, it does alert me to oncoming traffic. I wish that I could customize the audible alerts because the alert for oncoming vehicles is harder for me to hear, especially in the wind, than the sound for vehicles that have passed me. I also wish that the tail light modes would address the time left for each one based on the battery, I don't want it to run out of battery. Oncoming vehicle speed would also be nice.

I love the larger car icons and the red highlights on both the cars and along the vertical edges of my phone when faster cars approach from behind. The only thing I don't comprehend is there is a curved horizontal line across the face of the screen that doesn't serve any purpose as far as I can tell. Software artifact?
