Sonya is a free iPhone app developed by Sonya AS, designed for business and productivity purposes. It offers a convenient solution for recording and reporting expenses, mileages, and business trips effortlessly.

With Sonya, users can create expenses or log mileages with a simple tap, extract data from various receipts (digital and paper), track mileage using Google Maps including road tolls, support for per diem calculations on business trips with multiple destinations, and an innovative climate module that calculates emissions from travel activities automatically.

Additionally, the app allows users to manage expense reports, offers a user-friendly interface for employees, approvers, and administrators, and supports single sign-on through Apple ID, Microsoft identity, or Google account. Furthermore, it provides accounting integrations with Xledger, PowerOffice Go, Tripletex, and Uni Economy.

Users can enhance their Sonya experience by adding modules such as time tracking. More add-ons are expected to be available in the future.
