Lucid Dreaming app?

Not sure if this idea has been thought of yet but it's something I have been thinking of for a while, so here it goes.

Since technology is such a big part of our life, why not include Lucid Dreaming into that? As a technology reliant generation, adding something like Lucid Dreaming into an app would (in my opinion) improve our focus on Lucid Dreaming.

So the basic features of this app would be to make Lucid Dreaming a part of even your technological life. So this app would be DILD based, it would have notifications that would pop up on your screen every 30 minutes or so saying, " Are you dreaming?". Thus increasing the frequency of reality checks, then when you first install the app you would put in your timezone and when it's the morning it would be opened up with a blank page to write in your Dream Journal. With the dream journaling part it would have a button where you could post it directly to Dreamviews. Then this app would have tutorials on DILD, MILD, WILD and many more techniques. These are just some basic ideas I have.

I guess there is no direct point to posting this but I do have one question, how useful would this app be? Does anyone think it would actually help? Basically is it a good idea?

IF there has already been a post like this then feel free to delete this, just venting some ideas and asking for some criticism that's all.

Yes there is a reality check app. Just search up lucid dream in the app store. I don't know If this works on iPhone, because I use the iPad 2.
