I have used two other envelope products: YNAB and Neobudget.
I loved Neobudget for it's simplicity. However it was too simple and I wanted something more robust.
I then used YNAB. The concepts were good but the user interface was way too confusing. Looking at 3 months of budgets and how the money flowed between them was a headache. Not to mention the rollover balance to next month by subtracting from grand total. I found myself spending too much time at the end of month just getting it prepared for next month. It was just too much to grasp.
Then I found you guys, Goodbudget. The interface was simple to use. The web screen is 'clean' and uncluttered. The android version is beautiful and my wife can totally follow along. At the end of the day the user has to be comfortable in using the product. I am now at my one year anniversary and I am sticking with you guys.
Thank you so much for a great product.
