Savings Goals is an iOS app that allows you to track your savings goals. If like me you think in buckets of cash i.e. I need to save £100 for new phone, let's set up a savings goal of £100 and gradually add to it. First off the app is optimised for the iPhone 5.
UI isn't revolutionary but it's clear and includes instructions that assist you, although this could be slightly better positioned or a smaller icon used.
As you fill up your pots the number of coins move up the pot to your 'full' level, it's a nice motivator to see how close you are.
The Point: I like this app and there is also a free version that i'd recommend you checking out first.
