Welsh Christians will now have access the Scripture Union game which already has 140,000 users.
Funds totalling £30,000 were raised in just nine months after the idea for a Welsh translation was suggested.
Named Arwyr Ancora when translated in Welsh, it has all the same features as the English version and features Welsh television channel S4C's flagship children's presenter Martyn Geraint.
Aled Davies, Arwyr Ancora Project Manager 'We are really excited about launching Arwyr Ancora and have been encouraged by the level of support we have received from the churches in Wales to see this happen. This will not only be the best Christian app for children in Wales, but will be by far the best Welsh app for children in general'.
Arwyr Ancora was launched at the largest national children's and youth conference in the UK, Urdd Eisteddfod in Eisteddfod.
