Use Without Internet

We have partners across the world who are using Butterfly iQ in low resource settings to create sustainable healthcare. Since access to internet and other luxuries may be limited in such environments, we want to ensure you are able to use the Butterfly iQ successfully. 


To use Butterfly iQ, you need to download the Butterfly iQ App to your mobile device, create an account, sign in, and register your iQ while connected to the internet. For instructions on using your iQ for the first time, click here.

The Butterfly iQ is built to last a traditional shift of 10-12 hours with intermittent scanning, or for two hours of continuous scanning;.

The Butterfly iQ's charger is dual voltage. The voltage of the battery is 4.5 V. Removing or changing the battery is not possible.

Scanning Without Internet

The Butterfly iQ can be used without internet for several days. When scanning offline, all studies are stored locally in an outbox. You cannot upload studies to the cloud or share them between users without an internet connection. After an internet connection is made, all of the studies are uploaded to the cloud. Depending on the number of studies that must be uploaded and the strength of the connection, this might take anywhere from a few seconds to several minutes.

While scanning without internet, images are temporarily stored on the device until it is able to upload to the Butterfly Cloud. Please note that individual images taken with the Butterfly iQ are between 500KB and 1MB, and videos are 1-2 MB per second of recording. The Butterfly iQ app is less than 1GB. 16GB of free space should be sufficient to hold thousands of images and videos prior to internet connection.

Regular Updates

After the app has been downloaded onto a mobile device, the account has been created and the user has logged in, Butterfly iQ can be used without the internet.

Please note that Butterfly iQ app must connect to the internet every 30 days to upload studies and update its version of the Butterfly iQ app. These regular updates include firmware for the probe and security fixes for the device. If your device does not connect to the internet for 30 days or more, you will be unable to scan until connected to the internet.

If you require the ability use the Butterfly iQ for more than 30 days without internet access, please click here to contact Butterfly Support.

Viewing and Sharing Studies

We store your ultrasound data remotely in our secure Butterfly Cloud and do not use local image storage for uploaded studies. As a result, viewing and loading studies requires an internet connection. Upload to a PACS system, sharing studies with colleagues, or downloading a study requires an internet connection.

Multiple Devices

In some scenarios, it's possible that multiple users might be using the same probe or group of probes. Each of these users' mobile devices will need to connect to the internet every 30 days or less to continue using the probe.

When the Butterfly iQ Mobile App is updated, it includes firmware that will be installed on the probe when it is first plugged in following the update. This firmware update does not require internet access and can take between 15-90 seconds.

If two mobile devices have different versions of the app, the probe will need to update firmware every time it switches between the two devices. 

In the case of remote use, having one dedicated device associated with the Butterfly iQ might be preferred. In that scenario, you can control the probe and mobile device's app versions, and connect them to the internet on a regular schedule.
