Spectrum Analyzer added, app updated

Thanks to all your backing, we met our stretch goal of $32k, which resulted in us adding a spectrum analyzer to Mr.Ghost. It's live on the App Store now, and all you have to do is tap your waveform display, and it will switch over to spectrum. The spectrum analyzer window shows the frequency spread of your signal. It starts at 10hz and goes up to 20000hz on the far right. It helps you quickly see what frequencies you're looking at. A spike around 60hz on the far left is likely wall power.

There is also a new info button in the upper right for your reference on the various Mr.Ghost features and EMF in general. This will help new users.

Also, I've noticed some great ratings on the app store (thanks!) as well as some negative ones. The negative ratings seem to be coming from people that have not gotten Mr.Ghost to work at all, and instead of getting a replacement or contacting me, they have instead chosen to just give one star. If you have a problem with Mr.Ghost, there is a forum at mrghost.freeforums.net with a technical support thread and you can email me directly at info@theprotagonist.co. It's much more fun for both of us if we just get your Mr.Ghost working! 

Also, if you do like Mr.Ghost, I would really appreciate it if you would go to the app store now and rate it accordingly to help combat this problem, even just a little one line review helps immensely.

Thanks,
Aaron

      @Mario Thanks for the heads up. That does look like a double image. I'll fix that. And thanks for the nice review!

      Just checked the app listing on the store. It would be nice to see more other screenshots. All I saw was what looked like 2 copies of one image. (left a nice review, too)

      Yes, it should, but in iPhone compatibility mode. I can check it later today.

      does the app work with the ipad mini? I tried finding it, but it didn't come up.

      @Betty Hmm, if you're getting no difference, then it's probably not working. Send me an email at info@theprotagonist.co and I can get out a replacement! I think the forums are getting upgraded to a new design this week, so it may be a little dodgy right now.

      I'm not sure mine is working (get no particular difference pointing at flourescent, AC adapters, etc) but when I tried to register at the forum it failed with error: error calling pre_register2 -- Undefined subroutine &ProBoards::Include::db_quote called at /usr/local/PBV4.5/modules-new/register2.pl line 195.

      @Anthony Yes, a fluorescent light throws out a lot of EMF. You can also find more info on mrghost.freeforums.net. Make sure your baseline is set to around 7 or 8 as well. iPhone5's default to around 3, and it makes variations difficult to see.

      How am I able to know if it is working or not? Is there some source that will most certainly cause high EMF that I can test it against? Right now I have little to no fluctuation no matter where I wave the wand.
