We're about 2/3 months away from launching a small start-up webapp. We have lots of designs / screenshots of the app but so far we have kept what the app does a complete secret. Friends and family dont even know what it is.
We are fairly sure we know in what state we will launch the app but we don't know if the screenshots we have will change and or some of the functionality may be included / left out for launch.
Should we be trying to push our app at this stage or should we be waiting for a bit closer to launch. If we released them we'd be putting them on our app's blog (which needs finishing yet)
I would be concerned that competitors may see our work or people may think our idea is great and it would give them a lot more time to get a copy app made.
