Megan Fox, if you are reading this, you should give this one a try. And it's not because I think Megan Fox is a hottie (perse), it's just that she was a huge fan of the previous iPhone game that came from this designer -- Sally's Spa. Dan Kratt and Craig Rushforth previously worked at GamesCafe where they designed and produced Sally's Salon and Sally's Spa before breaking out on their own with BlueUnit Studios.
Hottie Hookups is the first product from that studio and is worth a look if you like time management or chaos management games. While the game is very well executed and delivers a lot of character, I was never sure I was personally sold on the gameplay. However, a free version was recently released so you can give it a spin.
