Routine does not support AI auto-scheduling. You have to manually drag and drop every task onto your calendar and rearrange your entire day yourself if anything changes. Even when you try to add an urgent or longer task, nothing shifts automatically, every adjustment is on you, and the app does not move or reprioritize tasks based on availability or priority. This makes time-blocking tedious and unreliable, especially if you're expecting your planner to build your day for you.

Routine does not support adaptive rescheduling. When your plans change or you need to add an urgent task, you still have to manually rearrange your entire schedule to fit the new task in. Nothing shifts automatically, so you end up fighting with the tool instead of trusting it to keep your day on track. This breaks down fast if your day isn't static.

Routine makes it harder to keep your head clear. The interface looks good, but the actual experience is messy and confusing. You get features like labels and database-style structures that should help you organize, but they just add mental load without giving you real insight. It's too easy to get lost or even accidentally delete core parts of your setup.

You still have to manually rearrange your entire schedule when priorities change, because nothing auto-adjusts. The way tasks and notes blend together just adds to the confusion, and you never feel like your priorities or next steps are actually clear. Instead of simplifying your day, Routine leaves you with more clutter and frustration.

Routine makes basic planning confusing and frustrating right from the start. Instead of feeling intuitive, you end up guessing how to do simple things and running into trial and error, even for core actions like scheduling or organizing tasks.

You can accidentally access database-level settings and even delete core structures, which should never happen in a daily planner. The labels system tries to add organization but just piles on more complexity without making anything clearer. The separation between tasks and notes is messy, so you're never really sure where things go.

The interface might look good, but the actual experience is clunky and unfriendly. You still have to manually rearrange your whole schedule if you add a longer or urgent task, so nothing about the planning flow feels easy or quick to pick up. This does not support a clear or intuitive planning methodology.

Routine only connects with a limited set of tools right now, mainly Google Workspace and Notion. You can add tasks from your email or Notion, but if you rely on other apps, you're out of luck. There's no real support for project management tool integrations yet, and bigger platforms like Slack, Asana, and ClickUp are still just "coming soon", not actually available.

There's also no API, so you can't build custom workflows or connect to anything outside of what's already included. If you need to centralize tasks, calendars, and communication from multiple sources, you still have to do most of it manually. This makes Routine feel pretty basic for integrations, especially compared to what you'd expect from a daily planner aimed at professionals.
