Femometer Ivy v. Mira?

Emily

Anyone use the Femometer Ivy <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a>? I am debating this smart tracker versus the Mira. The Femometer is a much more digestible price. Anyone have any thoughts? I use the Femometer

bbt thermometer and like it.
