Cool! Personally, I have set reminders to reach out to friends and family on my phone. I can therefore relate. The landing page communicates the honest intent behind this very well!
If I were to use your product, I wouldn’t want to cycle through canned messages. Do you plan on making this truly AI-powered? That would be a game changer. Let your app draft both kind messages and responses, and allow the user to review and edit before sending. Then make it learn from those edits, and boom, you’ve built a personal social assistant.
For now something more practical: as a typical user, I am not interested in my timezone. No need to show that specifically in such a large font.
