instatab

instatab is a web-based platform designed to simplify the process of tracking and splitting shared expenses among multiple participants. It is aimed at groups such as friends traveling together, couples managing household costs, or families and colleagues attending events, providing a straightforward way to ensure that expenses are divided fairly.

The platform allows users to open a new tab for each group activity or event, add participants, and log expenses as they occur. Each expense can be assigned to any participant on the tab, and the tool maintains a history of all transactions. instatab features an algorithm that optimizes tab settling by calculating the minimum number of transactions needed for all participants to settle up, which is particularly useful when there are multiple people involved. The service also supports multi-currency expenses, enabling users to set a default currency for each tab while allowing individual expenses to be recorded in any currency; conversions are handled automatically.

Users can invite others to join a tab via a generated share link, making collaboration quick and easy. The platform generates charts based on the tab data to help users analyze and better understand their spending patterns. For those who wish to conduct further analysis, expenses can be exported as a CSV file with a single click.

instatab is accessible through any web browser and is optimized for use on all devices, including mobile phones, without requiring an app installation. The sign-up process is minimal, requiring only an email address and a sign-in code.
