Good, but not great.
I've enjoyed using this product across it's user experience and function. It's delightful as a user and believe it's well thought out on how a user can approach with managing their time, tasks, and day.
BUT, there are downsides. The mobile and web app experience is night and day. The mobile app is currently in "beta" but even simple things like syncing the to-do's or tasks from the mobile app should be at least consistent with the web app. Otherwise, it creates 2 disparate sources of truth that do not align. For example, I can't get the to-do's or tasks from my mobile app to appear on the web app.
Aside, there aren't a lot of integrations to tie into this yet other than your standard email provider (Google, Outlook). Things like Notion and Zoom appear to be on the roadmap but if you're looking to create meetings, you're still bouncing into those your calendar provider app.
Last, whenever I have marked things as complete on my mobile app, they STILL appear, even after weeks of them being completed. It visually impairs and clutters my list of tasks, and nor does it auto move to the bottom, auto hide, or auto archive for some reason so my current uncompleted tasks are arranged in between completed tasks.
