Can I build this with Expo? Social Medication Reminders?

Hi all, can I create this with Expo?

I have this idea of creating a medication reminder app. If they remember to take their medication I want to be able to send messages - text, picture, voice - messages of support to my mom or dad. If they forget, I can also give them a nudge.

I haven’t worked on mobile extensively. A few questions I have is:

  • Do I have to use something like Twilio? If I do, what Twilio library works with Expo?
  • What should I use as a database? Parse?

Thank you!
