Pocket is as simple and straightforward as it gets in terms of finance apps. It allows you to create as many budgets or expense trackers as necessary, and have them recur on a weekly, monthly, or custom basis. Transactions are able to have notes and photos attached for reference. The app also includes the ability to use emojis as budget and expense icons, and add past and future transactions.
All you need is a way to track where your money is going.
