A beautiful, modern productivity app that seamlessly combines task management, Pomodoro timer functionality, habit tracking, and task sharing. I was tired of constantly switching between my to-do app, Pomodoro timer, and habit tracker app. Two of these apps required a monthly subscription, and the tedious process of switching tabs and logging my work in multiple apps was becoming overwhelming. Determined to streamline my workflow, I embarked on the journey of creating my own all-in-one app that seamlessly integrates all the features I desire. This app prioritizes user privacy, offering a completely free experience without any hidden paywalls. It remains independent of external apps and provides the convenience of sharing tasks through peer-to-peer (P2P) functionality.
