Colm O'Regan: There should be an app to spot assholes

Fair play to us. We do like to do our bit. The million downloads of a Covid contact-tracing app is a statement of solidarity in the fight against the virus. Also, it’s clear the Irish will go mad for free stuff. Apps, out of date Mi-Wadi, anything.
There’s only one thing for it: they need to make masks free and then you’ll see the uptake. We’ll wear two to show people the bargain.
