Dollarbird is a personal finance calendar designed to help users manage their finances effectively. It is an Android-based platform that allows users to track and forecast their money as easily as adding events to a calendar. Unlike traditional finance management applications, Dollarbird has a simple calendar-based interface where users can add, keep track and visualize their transactions.

One of the most significant features of this app is its auto-categorization with a hint of AI that helps classify transactions instantly. Additionally, it offers automatic balance calculation for each day or month and a transparent breakdown of past and planned transactions. The app also provides the option to collaborate with partners, family, or friends to manage finances and stay up to date on common money matters.

Dollarbird has received positive reviews from The Next Web, TechCrunch, Mashable, Lifehacker, The Guardian, iMore, and TUAW. It offers cloud storage, so users can access their data on all their devices, regardless of the platform. However, the full functionality is only available with a paid subscription.

Overall, Dollarbird is an excellent personal finance calendar that can help users plan ahead, manage their finances and make sense of their financial situation.
