Calmo is a functional app that uses the VR experience to reduce anxiety and pain during procedures. Designed and developed during NHS Hack Day 2018, Cardiff.

How to use Calmo

You will need:

  • A smartphone (only android is supported at this time)
  • A viewer (eg: these viewers)

You can then use the supplied calmo.apk to test out the app.

"We have future plans to publish to both Apple App Store and Google Play Store for free."

The Problem

Having blood taken can be an experience filled with anxiety and pain. The thought of this procedure can put people off having this simple procedure, which in turn can potentially lead to a delay or cancellation in treatments, affecting the patient's health outcomes and an inefficient use of clinicians' time.

Studies show between 3.5-10% of people have needle phobia.

The accessibility of VR technology introduces a new avenue of procedural distraction through VR.

User stories

As a clinician...

  • I want to be able to easily extract blood from the patient inflicting minimal pain and anxiety.
  • I want to extract blood from the patient within an average timeframe of 5mins
