App Crashing - Update iOS?

Caitlin

I didn't update <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> for a long time, then updated it a few weeks ago. Since then it's been slow and sometimes crashes when I log or open Health Insights. I've been keeping it updated since.

Could all this be because I haven't updated to iOS 10?
