There are five alternatives to Evangelizo for a variety of platforms, including iPhone, iPad, Android, Kindle Fire and Google Chrome. The best alternative is Chant Tools, which is both free and Open Source. Other great apps like Evangelizo are iBreviary, Liber Pro, Breviarium Meum and Universalis.
It is mostly intended to be useful for containing the Gregorian Mass propers as well as the Gregorian Mass ordinaries as found in the Liber Usualis, and transcribed on GregoBase (http://gregobase.selapa.net) and there may be some mistakes in the chant.
Universalis Publishing was started in 1995 with the aim of harnessing computer technology to help in enriching the spiritual life of Christians, specifically by making the liturgical and devotional resources of the Catholic Church available on the new electronic media.
