Research – Supplementation App (is it tarpit?)

Hi! I am working on building a mobile app to support and enable adherence to taking supplements. Think of those water-reminder apps (or even period-trackers)

I tried to look up on some user insights and I was unable to. I thought this would be a great place to ask. So here are some questions...

1/ How do you keep track of your supplements? Some app? Manual? Excel sheets?

2/ What feature do you want to see in an app made for this? Give me your biggest pain point. And the largest challenge.

3/ What would you want to pay for this app? If you already use an app, what do you pay for it.

4/ Will you be ok for a longer conversation? In exchange, when the app comes to life, i can offer you a free tier. PS: The app is in my head right now. Havent had the chance to even start.

5/ Is this a tarpit idea?

6/ What wedge can I drive that cal.ai / noom etc havent so far?
