iOS Reminders

It would be great to integrate with the iOS reminders app, since it comes default with all iOS devices!

I would like to have a feature that randomly reminds me of sth, let’s say getting up from the desk and walk

unfortunately, iOS does not give other services access like other companies, (google, microsoft, jira, atlassian, discord, samsung, etc.) do

Hmm that may not be true now. There are apps Reminders menubar that is able to access mac reminders:
