Canolfan Peniarth will be exhibiting a new, unique app at the National Eisteddfod in Monouthshire this year on University of Wales Trinity Saint David’s exhibition stall.  The main focus of activities on Tuesday 2 August 2016 will be this innovative App, that will be installed and displayed on a 42 inch tablet.  People attending the Eisteddfod on Tuesday will be able to test their ability to mutate accurately, and to see how the app works.

The aim of the app is to help Welsh speakers and learners to check mutations. There are two elements to the app, the first being the search element that includes those words that will cause the immediate word that follows to mutate.  The second element is the revision element and is aimed as a tool to aid revision of the mutation rules.

Since its launch recently, the response for the app has been overwhelmingly positive, with a number of organisations, teachers, students and the general public downloading the app for their daily purposes.  One of those is the Children's Commissioner, Sally Holland. The Commissioner said, "I have to say that I use the app almost every day, especially when I Tweet, as these messages are so public. I have recommended the app to everyone in my team".

Louise Jones was a teacher at Ysgol Gyfun Bro Dinefwr and has been using the app prepare lessons for school children. Louise said, "Ap Treiglo has been a great help to me when trying to write classroom resources in Welsh. The app explains the mutation rules very clearly and is easy to use ".

Jeni Price, Project Manager at Canolfan Peniarth, who led on the development processes of the app said, "Following a successful bid we received funding from the Welsh Government’s Technology and Digital Media Fund to develop this exciting app that will help everyone who communicates in Welsh, whatever their level. Our hope is that it will relieve poeple’s worries and increase their confidence to use Welsh in every aspect of their lives ".

Ap Treiglo is one of five new apps that Canolfan Peniarth has published this year, with three of those apps, including Ap Treiglo, language apps. All of Peniarth’s apps will be displayed on special 42-inch tablet at University of Wales Trinity Saint David’s stand in the Eisteddfid throughout the week where all are welcome to come and experiment.
