FAQs

  • The narnar app is designed for iPad Pro (11 inch, 12.9-inch, and 10.5-inch models are supported). We highly recommend the Apple Pencil and Smart Keyboard. The app will still work without them, but you will not be able to fully enjoy the full usability those tools provide.

    How it works:

    • get an iPad Pro + keyboard + pencil,

    • download the free version of narnar app from the App Store,

    • start using the app, let us know at support@narnar.co if you need more help,

    • let us know if you are interested in participating in our beta program.

  • DICOM format is limitedly supported for reading files generated by systems from major ultrasound vendors.

  • Once you have the app installed, simply take a screenshot by pressing the home and power buttons. You will be prompted to submit feedback by email. Or contact us with your suggestions or bug reports directly at support@narnarhealth.com

  • Ask us about our beta program if you are interested in helping us to develop new features.
