Mae ehangu’r ap yng Nghymru’n cyd-fynd ag ymgyrch genedlaethol o ran sut gall pobl yng Nghymru gefnogi’r rhaglen Profi, Olrhain, Diogelu GIG Cymru yn y ffordd orau, gan gynnwys dim ond cael prawf os ydynt yn dangos symptomau; hunanynysu pan fo angen; a gweithio gydag olrheinwyr cysylltiadau lleol os cysylltir â hwy.
The roll-out of the app in Wales coincides with a national campaign around how people in Wales can best support the NHS Wales Test, Trace, Protect programme, including only getting  a test if they are showing symptoms; self-isolating when required; and working with local contact tracers if they are contacted.
