The authentic one.

After participating in the beta testing of this product, its wonderful to see the Devs. have this out in the App store for mac.
I was a little too excited and purchased Call pad by accident, and the developer of that one clearly did NOT put in nearly as much thought into his app, nor did he test it properly prior to release.
This product, once announced, only served to give the “other” developer a means to ride the concept on its coat tails and trick people into purchasing his instead. That logic wont get you far in life my friend.
As most innovative writers and developers at/for Apple have learned, imitation is Not always going to inspire flattery. Now that I have my official version of this concept, it is easy to see who spent the time to polish thier product, not rush it to release, and sincerely worked very very hard to make it as lovely as the rest of Yosemite in its design. After all your efforts E & H, I still bucked up a second time to get the real deal, and It is my hope that this review will assist others in not rushing to buy the early clone of this idea. It is only $1.00 but it is the principal here. If it were up to me, this app would be a permanent inclusion in a future version of Mac OS X. Huge kudos to the devs for this. Fantastic work.
