Looking for Honest Feedback on My New App Store Screenshots

I've been redesigning the App Store screenshots for my medication reminder app and would love some honest feedback.

A few questions:

• Is it immediately clear what the app does?
• Which screenshots are the strongest?
• Which screenshots would you remove or redesign?
• If you searched for a medication reminder app, would these screenshots convince you to download it?

I'm trying to improve the App Store conversion rate, so I'd really appreciate any brutally honest feedback.
