For everyone wondering about this method, it's called the sympto-thermal method and is <i>not</i> the same as the rhythm method. Planned Parenthood lists it as 99.6% effective with perfect use. See the "What is the Sympto-thermal Method" section in the link below:<p><a href="http://www.plannedparenthood.org/health-topics/birth-control/fertility-awareness-4217.htm" rel="nofollow">http://www.plannedparenthood.org/health-topics/birth-control...</a>
Albeit a great app, this method is less reliable than having proper birth control at hand.<p>I see mentions of "But it's 1.8% failure rate!" - thing about Cumulative Probability is, that is a pretty high number of failure after about 10 years.<p>After 10 years you have a Cumulative Probability: P(X = 1) of about 15% of getting pregnant.<p>If you don't want to be a dad/mom - use a condom. Or go double dutch.
I'm a little bit confused. The title mentions birth control but the website is talking mostly about fertility. Is this a tool to help women get pregnant or prevent pregnancy?
Misleading title.<p>It's a fertility tracking app. There are dozens of those.<p>When I see "{physical thing} as a service", I expect some sort of monthly fulfillment service, like Dollar Shave Club.
The app looks great. Does it work for the Creighton Model (<a href="http://www.creightonmodel.com" rel="nofollow">http://www.creightonmodel.com</a>) as well?<p>Also, you may want to get added to this list: <a href="http://contraception.about.com/od/naturalmethods/tp/fertility_apps.htm" rel="nofollow">http://contraception.about.com/od/naturalmethods/tp/fertilit...</a>
> Upgrade your account to practice natural and effective birth control, get pregnant easily, or take control of your reproductive health.<p>"Get pregnant easily" is not something you should be advertising. There are tons of reasons why someone can have trouble getting pregnant that are completely external to your app. Just a heads up.
Kudos to you, it's alway great so see people talking about natural birth control methods without mentioning <i>God</i> or <i>religion</i> in the same sentence. It's virtually impossible to find good resources about the sympto-thermal method in English without landing on a very Christian-oriented website.<p>But I'm wondering: What's the business model you have?<p>I'm asking, because I'm in the same space. Mostly in Germany, but I also have an app for the English-speaking population: <a href="http://mynfp.net/" rel="nofollow">http://mynfp.net/</a><p>It costs 5.99$ and it's certainly nothing I can live from alone. However, the app is just an "appendix" to my SaaS business which is the same thing, but bigger and better, which generates revenue to be sunstainable in the long term.
Seriously, rhythm method is not effective birth control (24% failure rate/year). Please don't rely on it!<p><a href="http://en.wikipedia.org/wiki/Comparison_of_birth_control_methods#Comparison_table" rel="nofollow">http://en.wikipedia.org/wiki/Comparison_of_birth_control_met...</a>
Q: What do you call a woman who depends on the rhythm method for birth control?<p>A: A mother.<p>As a tool to help you get pregnant, awesome, kudos, very well done.<p>Promoting it for birth control? Not very clever.<p><a href="http://www.plannedparenthood.org/health-topics/birth-control/birth-control-effectiveness-chart-22710.htm" rel="nofollow">http://www.plannedparenthood.org/health-topics/birth-control...</a>
