Alternative to Google Tasks?

Can I get some suggestions to alternatives for Google Tasks or Microsoft To Do? My problem with them is that you can't use reminders for them that will alert you of tasks you've set, via Gmail or Windows Calendar or Android, on the given day. Eg.: I set some tasks for today, then today when I open my phone I will see notifications about tihs . Same on Windows.

If you sign in to your Google Account on your computer and your phone (Gmail) and set them to Sync, you will get notifications for reminders in
Google Calendar or Tasks list on both devices.

I just tell Google Assistant what to do and she does it!
