GutSync - Track food, find triggers, heal your gut — all on device.

Hey Product Hunt! 👋 I'm Deniz, and I built GutSync because I couldn't find an app that actually helps you figure out which foods are causing your symptoms. Most food tracking apps are calorie counters. But if you have IBS, food sensitivities, or you're doing an elimination diet — you don't care about calories. You care about: "Why do I feel terrible every Tuesday?" The answer is usually hiding in a 24-48 hour delay between eating something and reacting to it. That's why pen-and-paper food diaries don't work — you can't see the pattern. GutSync's correlation engine looks at a 2-72 hour window and tells you things like: - "Dairy → Bloating: 78% correlation" - "Gluten + poor sleep = your worst days" - "Caffeine actually isn't a trigger for you" I also built in elimination diet protocols (Low FODMAP, AIP, Histamine-Free) because I know how confusing it is to do these on your own. Everything runs on-device. No account, no cloud, no tracking. Your gut data is nobody's business. Would love your feedback — especially if you're dealing with IBS, SIBO, or food sensitivities. What features would make this more useful for you?
