Solo dev, launching Friday. My plant app does something I can't really justify on a spreadsheet: when a plant dies, instead of deleting it, it writes the plant a little goodbye. No retention math behind it, I just couldn't stand the delete button. Did I waste my time or do small "useless" touches like this actually matter to you?
A quiet care journal for the plants you keep. Mossly learns what each plant needs, remembers every drink, and can name what you're growing from a photo. For iPhone.
