    I have an iPhone and didn't use a charting app, but I would bet someone here has a good idea for you! Have you tried searching some infertility blogs to see if anyone there has suggestions as well?

      I have an iPhone and I searched for free trackers and I found a bunch. I see the some of them work for Android too.
