Monefy (Android)
La use un par de meses en versión free y es totalmente funcional. Ahora compre la versión premium y anda joya. Si o si tenes que tener disciplina para anotar todas las transacciones, si no no te sirve de nada.
>If you usually pay for things in cash or you don’t want to allow these apps to access your transaction history, you can enter all the expenses manually, or even just list them in a spreadsheet or a notebook you always carry with you.
I recommend this instead, I've been using it for months myself. Carrying something extra just for budgeting is a sure way to get someone discouraged from even trying. Plus it has the occasional eye candy to trick our monkey brains into being happy.
You might find this app useful if it's available in your country and have a compatible device. I've found it to be the nicest looking and easiest to use app for keeping track of expenses so far.
