This has been life changing! And I think a must-have (at least in concept, not necessarily this app) for all international service workers. The function of the app is lay out a budget, that can only be "budgeted" as the money is in hand. Then, as you buy your groceries, fuel or pay your rent, you immediately place the expense in the app. This in theory (and has been very close) gives you the real time money in your account so you don't overspend money that you don't have. It synchs between devices, so Adam and I will also have each other's account information on our own devices. This has allowed us to be more proactive and prospective about our spending to guarantee that we are living within our means and within our budget, as opposed to looking at our spending at the end of the month (after we have already spent it).
It is all these small details that will be so important in the next season of life.
