Slow updates to syncspace

I downloaded the free syncspace app on my ipad and iphone4. Both devices are connected to the same wifi network. I am having problems with the screens keeping in sync though.

I start a whiteboard and set it as shared. I can see it from the other device in the "nearby" tab and connect to it. However, it is very slow to make updates. For example, if I draw on one device it may take 20-30 seconds to show up on the other if it shows up at all. It I draw on the device that connected to the first I can't recall ever seeing the updates on the first device. Is there something I am missing? Does the sync require connection back to a server somewhere that may be slowing me down?

As comparison I tried the app whiteboard from the app store and updates to it are immediate across devices.

    SyncSpace sharing works by relaying all connections through a central server at This lets people share with each other no matter where they are. It also means that drawings can be shared by people even if they are not online at the same time.

    The server runs on an Amazon EC2 instance on the East coast of the USA. Once the initial load is finished the connection should be mostly snappy. Images may take a bit longer to upload/download on each side, but the total delay on a good connection shouldn't be more than a second or so. If you are running behind a strict firewall with a proxy then that may be the cause of longer delays, but that all depends upon the proxy.

    It might be helpful to try opening the drawing link on a browser (either on the iPad or a nearby desktop). If you open the drawing link and select the "View in Browser" option and experience the same delay with the same network configuration then it is likely that the problem is in the network and/or a proxy.

    The "nearby" local discovery is simply used to discover shared drawings that are open on nearby devices. Once discovered, those drawings are synced through the main server.

    We will be releasing private SyncSpace servers that anyone will be able to install on their own private networks. If you or your company might be interested in such a service we could make a preview version available.

    That is disappointing to know. That was not how I understood the description of the software to work. I assumed that if the 2 devices were on the same wifi network they would talk directly. It would appear that syncspace is not what I am after as a personal user. The use-case would be that my wife and son would use 2 iPads for homeschooling purposes only and as such would be in the house on the same wifi network. The delay in updates is not going to work for us then. Thanks for the quick reply.

    I would be really interested in having a local server for my company. Could you tell me more ?

    Hi Wilfrid,

    Absolutely! We have planned for a while now to license the SyncSpace server. I'd be happy to help you setup a server to use with syncspace (or even to do it for you).

    Can you email me ([email blocked]) with some details of your company such as how many clients you expect to have and whether they'd like to access SyncSpace from either iOS, Android or the web?
