How to keep todoist logged in on my iPhone.
Is there any way to stay logged in so I don't have to re-enter my password on my iPhone?
unfortunately, there's a bug which causes this behavior. We are aware of it and are going to fix it in the new version of our iOS app.
Furthermore, we will soon release a new native app which should fix this issue permanently.
Sorry for any inconvenience.
For now, as a workaround, you could try to use the Todoist mobile website http://todoist.com/m to access Todoist on your phone.
