It's all in the title. Do you ever feel overwhelmed by the sheer number of tasks on your to-do list? Adding all your tasks only to be faced with a seemingly endless list can make it hard to get anything done. That's why I created Underload, a to-do list app for iPhone, iPad, and Mac that only shows you one task at a time. You can add all your tasks, but you'll only see the next one you need to tackle. You get a clear, linear path forward, a singular focus. Best part is, it two-way syncs with Apple Reminders, so your tasks sync across all your devices and you can keep using Siri, HomePod, Shortcuts, and whatever other integrations you're used to to manage tasks.
