Spend Together, developed by Kyrylo Kuzyk, is a free app available on iPhone that helps manage joint expenses with ease. It is ideal for trips with friends, roommates, couples, or any other IOUs. The app eliminates the need for paper bills and saves time spent arguing about who owes whom and how much.

With Spend Together, inputting bill details is all it takes to calculate group debts and suggest optimal payments to settle them up. The app also allows shared access to the group debts and data by sending a personal invitation link to friends. A comprehensive report shows your personal share in group expenses, giving you an overview of where your money goes.

Spend Together supports all currencies and forms reports using up-to-date exchange rates, and all changes made offline are securely synchronized with the server when internet connection is available. The app also has Apple Watch support, allowing users to add expenses and track group debts on the go.

Privacy is a top priority for Spend Together, and no registration or personal data is required. However, an optional paid subscription, Spend Together PRO, is available. It unlocks advanced features such as detailed statistics of expenses, an unlimited number of groups for every life occasion, modifiable exchange rates, and color customization.

Overall, Spend Together is a convenient and efficient app that helps manage joint expenses effortlessly.
