I use excel spreadsheets for tracking information at work, I use the column sum method, positive or negative numbers manipulate the sum column, each column can be a specific component. As you add or subtract, it keep the current sum relevant.
It's easy to do and they probably have some form of spreadsheet on both Android and IOS that is capable of being setup to give you the tracking information you want. If so, it could be synced across multiple platforms and devices using the cloud.
