Good

Good, except there is no way to change app to english. It is always in spanish, and they removed the function to test the app as well
CAcute but lots of ads

Eficaz

La aplicación es fácil de utilizar y de entender si tienes un buen servicio de datos o de Wi-Fi. Usualmente recibes los mensajes con anticipación he probado algunas otras y esta es de las que funcionan mejor.

Leaves notifications that I can’t clear

For an entire week there’s been a notification that won’t go away. Deleting this app didn’t even fix it. Deleting for good now
