Does anyone use <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> along with glow? I love glow so much more but for some reason I think <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> is more accurate with my cycles. I had what looked like EWCM on the exact day <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> said I ovulated and glow said it was a few days before that. Just wondering what app others liked more for accuracy?
