chessdb App - Is It Worth It?

Is anyone using the chessdb iPhone app?  Is it worth it?  Was thinking of getting it but saw it hadn't been updated since 2010.  This gave me pause.  Any thoughts?

I have just now downloaded it. I love it, thanks for the tip.

I had it on my iPad for awhile. It may be there still. If I used it, I found it less useful than other apps.

Thanks.  It looked interesting but I wasn't sure.
