Glow premium- is it worth it?

Ca
Considering downloading Glow premium because I am pregnant and using Nuture. Is it worth it, or should I not spend the money? 
Side question (not for the poll) If you download premium- can you use it for any of the 3 <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow apps</a> at any time?
