I'd caution against obsessing too much over pitch. Realistically, the higher you can go, the better, but you'll be able to feel if it's taking undue effort, and in this sense, you don't really need these fancy pitch apps. In most cases, glottoplasty would be needed to be really consistently happy with the pitch (i.e. always in or close to female average pitch range.)
But in a practical sense, and especially if you're older, your pitch can actually be fairly low and still sound female, especially if your prosody is varied enough (upwards inflections, etc.) It's also possible to be very high pitched and still sound male (Ross Matthews, anyone?)
More focus on larynx placement and vowel formation. If you studied the pitch range of female voice actors (Kate Mulgrew) you'd be floored at how incredibly low they can go and still sound female, while rarely even entering the average female pitch range. That's because they have these two traits down solid.
Battles of "well i'm 150hz and shooting for 200hz" are kind of a moot point compared to this.
