Good Expense Tracking, Even Greater Budgeting.
I've been using some Expense Tracking app (which is available in Google Play) - with export data features and creates my own Spreadsheet to mess around with the data using PowerPivot features.
And I thought I'm already on the right track. One thing I realized after I found YNAB is - I've been doing it wrong. Well to be fair, not 100% wrong but definitely not doing the best I could (for my personal finances).
I have been just doing EXPENSE TRACKING and REACTING to the end results of my tracking, and that's it. Nothing more, nothing less. I know where I overspent, but does not have proper PLAN to action against it; and that's how limited "Expense Tracking" could bring you to.
After finding out about YNAB, I realized that I could do better - instead of track & react, I should be planning, tracking, and take corrective actions; a.k.a "Budgeting". With this software, it combines everything that I currently have (Android App + Custom Spreadsheet) PLUS bonus features - which I could not replicate in my Custom Spreadsheet. If you haven't give it a try and are looking for personal finance app/software, you SHOULD give it a try.
