The Alpaca Dashboard mobile app is an open-sourced example application built on React Native, designed to be a minimal skeleton for developers to add features and refine designs. The app allows users to log in to their Alpaca trading accounts, track performance and buying power, view open positions and orders, take emergency actions, and manually place trades or disable API access. This feature is part of the growing Alpaca community's efforts to collaborate on coding snippets and example algorithms, with the goal of accelerating progress and innovation in mobile app development.
