Is Evie a strong enough name?

I’m in love with the name Evie! (Like <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>-e) I feel like it is a complete enough name, but DH thinks it’s more of a Nick name. I know Evelynn could be a full name for it; but I’m looking for other suggestions because I’m not sold! Thanks!
