How to validate this - I’m building a 'Chat-Based' health app that handles nutrition (macros and calories), exercise, and grocery inventory in one stream. Looking for honest feedback on the idea itself.
I’ve been working on this for a few weeks to solve my own frustration with tracking apps. I wanted a single tool that handled the entire loop: knowing what’s in my kitchen, tracking my calories and exercises, and planning my meals. I wanted it to be super easy to log - text, voice, photo based logging (low friction) and realised I can track colories and exercise through it. Now it can have your preferences, know your likes/dislikes, allergens, goals (lose weight, gain muscle, etc) and suggest stuff based on that.
The features I built to solve the burnout:
Context aware + chat based logging: Text/Voice logging for meals and workouts, e.g., "I ate an omelet, or walked 30 mins", It logs the macros and deducts the eggs from my inventory, or checks my height and weight, estimates walk calories and adds them to burned, all instantly with one command.
Personalized Recipe Gen: It knows my macro targets, allergens, and current inventory to suggest meals I can actually cook.
Smart Substitutions: If I’m missing an ingredient, it instantly finds a swap from my pantry.
It’s designed to remove the cognitive load of diet logging. I’d love some feedback on the concept, is this something you'd use, or is it trying to do too much?
