Yea I have used Account Tracker and think its also a very good little tool. There are also free ones you can get from your bank, just create an online account (not a bank account) and you can downloads of grrat free tools from them.
There are a number of envelope-based budgeting apps. The one I use is You Need a Budget. It's not cheap to buy but it has paid for itself easily in terms of the savings I've been able to make by understanding my finances better. There's a substantial free trial as well, so you can try before you buy.
This is a thread I had last year comparing some of the alternatives - although it was limited by needing things which would run on a Mac.
Hi I was recommended a budgets envelope app but can't remember what it was! Ideally I want one I can have on my iPhone and iPad which syncs. I like the envelope idea so I can set out my spending in advance. Any ideas? Thanks
