Concerns raised over UK Covid-19 contact tracker app performance.

Dorset firm design QR code app claiming NHS bluetooth app will be unreliable.

In May 2020, the UK Government plans to release an app to track people reporting COVID-19 symptoms.

The app is designed to track when people come into close contact with each other using bluetooth connections. When a user inputs coronavirus-like symptoms to their device, phone alerts would be sent to people they've been in close proximity with, and telling them to self isolate.

But a computer company in Poundbury, Dorset has told Βι¶ΉΤΌΕΔ Radio Solent reporter Laurence Herdman that the Government-backed app is "fundamentally flawed", because it relies on bluetooth.

Poundbury-based Deane Computer Solutions claim bluetooth diminishes distance accuracy, performance and security. The company has designed an alternative Covid-19 tracker app that uses QR codes. Managing Director Darren Scott says there is no personal information, and therefore it can't be exchanged between users, and it's not at risk of data breach.

The NHS says it has a way to make the software on its app work "sufficiently well".
