iPhone Health App sync

Carla
Alright so I recently re-joined / re-downloaded <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app on the iPhone App Store. I was previously using a different period-tracking app which wrote data in the Health App. I have since started using <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> again, so my question is– is there any way for <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> to sync (download?) the data written in the Health App (as regards to my period cycles etc.) because right now it's showing me no history of periods (because they weren't logged in <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>). 
I hope I made myself clear, and I appreciate any help.
