Envy is a free iPhone app developed by Chimpanzee LLC in the category of Business & Productivity, specifically under Finance. It aims to simplify budgeting by digitizing the cash envelope system. With Envy, users can create unlimited envelopes to organize their budget and manage their money easily.

One of the key features of Envy is the ability to quickly deposit funds into all envelopes with just one click. Users also have the option to exclude certain envelopes from this feature. Envelopes can be renamed and their budgets can be updated without losing any transactions. Additionally, users can easily move transactions from one envelope to another, start envelopes with negative balances, and view all transactions in one place outside of each category.

Envy offers a user-friendly interface, allowing users to enter and edit transactions in under 5 seconds. Users can also export their transactions as a CSV file and sort them by date, transaction, amount, name, deposit, and color. The app is based on the user's local currency and is developed by a dedicated solo developer who responds to emails.

The app also offers a free version that provides limited envelopes and viewable transactions, allowing users to try out its functionality and ease of use before making a purchase.
