If you have an Account ID on Sekai Camera and wish to re-download the application or to install the application on your 2nd iPhone, you can use the same Account ID to login. If you can’t login, please check the following:

1. Input your Account ID in the login panel. An Account ID is what you have registered upon the first use of Sekai Camera, and it is not your nickname or email address.
2. Your network connection may be unstable or the server may be busy. In that case, please wait for a short while and retry, or move to a location with a better network connection.
3. The service may be in the middle of maintenance work. Please check the maintenance information on this website or on Twitter @sekaicamera.
