Thank you for your comment! Yes, in the moment there is only an Android app, but the developers say that an IOS version should come "soon". How soon that is, I don't know.

So not to spam my main account with my daily actifit posts, I created a second account. You are right, this is not the best solution, but this project is still in the "Kinderschuhe" and so I believe this all is changeable. I can see the potential of the project and hopefully they find finally a good way to manage it.
