The Metrônomo CCB Free is an Android app designed to aid in the study of the correct tempo for the execution of Hymns contained in paragraph 5 of the Christian Congregation of Brazil. This app was developed by AMORAESDEV.COM and is available for free.

With this app, users can easily adjust the tempo and time signature to match the Hymns they are studying, helping them to learn and practice at the correct pace. This app is not for profit, and the revenue generated from ads is used to fund the maintenance costs of the app as well as the MTS Mobile application.

Overall, the Metrônomo CCB Free is an excellent tool for anyone looking to improve their performance of Hymns in the Christian Congregation of Brazil's Hinário nº 5. It is worth noting that this application was developed by personal initiative and has no link with the Christian Congregation of Brazil.
