No, and yes. We do not have native apps for Android and iPhones yet, but it is work in progress, so we will keep you posted.
However, since Cobbl is a Web App, we have optimized it mobile browsers as well. You can use Cobbl through your phone’s browser, e.g. Safari or Chrome. You can view boards, upload photos and enjoy Cobbl while you are on the go. It is simple to email photos on your phone to the Cobbl Board email address as well. Just save the board email to your address book and you are good to go.
We recommend that you add the site to the home screen of your phone. It is easy and convenient.
