Which App should I go by? HELP!


I am posting this because I am confused. I have both <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> and the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> download and use both. <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> is showing me that I should've been in my fertile days this past week however I had an LH surge on February 28 and March 1 (a slightly faded LH Surge March 2 (which we BD On all three days)) the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> showed me my fertile days around my LH surges.  Which app should I go by? Also would you all say that I'm 4 DPO?
