As your first campaign you should try to catch a large audience like people in US over 18.. that's it ! and test your ad copy first... then base on your data you can decide the perfect demography for your app.. Are you going to blow money on the first second and third iteration ... the answer is yes but at least you will know exactly what's work best for your app on facebook...Ad campaign optimization is not easy. My best advice is to use a great ad tracking tool... you must track everything... no guessing game here... Finally a small variation is you copy and/or app presentation could have drive better results with the same $30.....don't give up :)
