Mint. Adaptu. HelloWallet. All great budget and spending apps.
I will still keep all my physical receipts, manually input my expenses, and plan out my budget through the good ole Excel spreadsheet.
Why though? Why make an extra step in your weekly routine to do book-keeping?
Because I want to literally be hands-on with my money when I keep tapping my cards. Apps are great because they compile everything for you in a nice diagram to see where you are spending the most. However, when handling receipts and logging it in individually yourself, this truly gives you the pain of how every little purchase adds up.
When everything becomes digitized, it is much easier to be disconnected from your cash flow. Looking at every receipt from my purchases that week forces me to revisit regretful purchasing decisions and think before another impulse buy. Editing my spreadsheet keeps personal finance top-of-mind, and prevents me from having a passive attitude towards it.
