I'll build a GERD mobile app for free

This is a repost (moderators, please do not ban me for posting it twice).

I will build a GERD app for Android and iOS free of charge. As I was planning to create it for my own use, I thought, why not develop it for everyone?

Previously, I did not receive enough attention—perhaps the wording was not sufficiently explanatory—so I have decided to post it again using simpler language.

Please share your ideas and suggestions on how to build it. I have some initial concepts, such as a food log and tools for managing anxiety and medication, but I would appreciate your feedback on what features the app should include.

Upvote the best suggestions so that they appear at the top.

Or tell me to go to sleep (if my idea to develop an app for everyone is not practical) so that I don't waste any of your time or mine.
