You're REALLY PASSIONATE about your special interest, and we want to help you lock-in and build something great around it! Most "focus" apps don't work well for neurodivergent people, so we wanted to make one that would! We used science-backed methods to create tools that make it easier for people like you to be SUPER LOCKED IN while you make an impactful project around your special interest! For starters, we've got a tool that takes your goal and gives you an actionable to-do list to get there, so you don't need to spend any resources overthinking planning! Along with that, we let you write down your distracting thoughts during work sessions so you can stay focused and come back to them later! The app is 100% FREE, because we want as many passion projects as possible to come out of this! We'd love it if you shared what you build on social media :)
