BLOOM⁴³ app now available in Macmillan's Cancer Support App Library
July 22, 2026 — Plexāā are proud to share that the BLOOM⁴³ app is now in the Macmillan Cancer Support App Library.
Macmillan Cancer Support is one of the UK's largest cancer charities, providing information, guidance, and emotional support to people living with cancer and their families. As part of that work, Macmillan partners with ORCHA (the Organisation for the Review of Care and Health Apps) to run a curated library of digital health apps, giving patients a single, trusted place to find tools that have been independently checked for safety and quality.
Every app in the library, including BLOOM⁴³, has been independently assessed by ORCHA for safety, usability, privacy, and security, so people living with cancer can find trusted tools with confidence.
For patients preparing for or recovering from breast surgery, particularly those navigating a cancer diagnosis, this means BLOOM⁴³ now sits alongside other Macmillan-vetted resources as a tool they can turn to with reassurance, whether they're based in the UK or discover it through Macmillan's wider reach.

The BLOOM⁴³ app is free to download from the App Store or Google Play.
About Plexāā
Plexāā is a pioneering UK MedTech company focused on improving surgical outcomes through innovative solutions. Their flagship device, BLOOM⁴³, enables patients to supraphysiologically precondition their skin, potentially reducing the risk of wound healing complications such as infection and skin necrosis, which affect 1 in 3 women undergoing breast surgery.
BLOOM⁴³ is the world's first fully wearable device worn next to the skin before breast surgery. By gently warming the area, it stimulates the release of Heat Shock Proteins (HSPs), naturally occurring proteins that trigger the release of carbon monoxide into the tissue. This vasodilates the blood vessels and improves blood flow to the skin, priming it to heal, an effect shown to help prevent wound healing complications in proof-of-concept clinical trials.
