Is it correct, that I can´t use ToDoist on my mobile if I don´t have a connection to the internet?
Vielen Dank vorab!
That's not correct. Our mobile apps have full offline capability and you can use them without an internet connection and synchronize the changes later, but please make sure that you stay logged into these apps. For the first time when you install them, you must be online to log in and perform the first synchronization. If you don't log out, you can then access it offline anytime.
