Your personal trigger foods — found by AI in days, not months. Snap meals, log symptoms, and watch Gutsy pinpoint exactly what's causing your flares.
Most gut health apps blame your last meal, but food takes 6 to 72 hours to move through your digestive system — and that timing is different for every person. Gutsy learns YOUR personal transit time from your logs, then links every symptom back to the meal most likely behind it, not the one you ate an hour ago. This is why our users finally identify triggers they've been chasing for years.
THE 6-WEEK TRIGGER PROGRAM
86% of IBS patients improve within 6 weeks of identifying their triggers (Nanayakkara et al., 2016). So we built a 6-week program around the science. Use Gutsy daily for 6 weeks to surface at least one of your food triggers. If the program doesn't deliver that, we'll personally support your refund request through Apple.

Your gut has a story. Gutsy helps you read it.
No one understands the physical and emotion pain people with IBS, chronic bloating, SIBO etc go through. It takes over every day life, you’re constantly in a horrible mood and feel lost. It feels like your body is just broken. Flares get worse, bloating gets worse - and we have no idea what is causing these problems. Doctors and supplements cost thousands - still no answers. Gutsy is the ONLY thing that makes me feel like I can finally get control of my body back. It tracks everything I eat and my symptoms to create a full pattern dashboard that identifies EXACTLY to the INGREDIENT level what is causing my flares/bloating. I also love that it allows me to track my bowel movements, water intake, supplement stack etc. Not to mention the Gusty AI chat bot knows my gut better than I do - gives me insights, checks in on my mood, and gives me data that no doctor ever could. I also love the motivation quotes every morning and how sleek/modern the app feels. TL;DR - if you’re suffering and feel lost - this will be your solution. Be consistent, your insights and patterns will be live changing.

I read this review three times before responding. What you wrote about feeling like your body is broken, about flares getting worse with no answers, about the cost of doctors and supplements that lead nowhere - that is the exact pain that kept me up at night for the better part of this year building this. Every late night, every rewrite of the trigger algorithm, every conversation with people in the IBS community shaped what you're holding now... Thank you for being the kind of user who shows up consistently enough for the patterns to surface. The insights you're getting now will only get sharper!- Founding Team at Gutsy
Must Have App for anyone with bloating issues!
BethanyF.
Lots to say here but the main take away is that - if you’re bloating after eating, it’s NOT normal. You need to figure out what is causing your bloating/cramping/stomach aches before it turns into IBS, SIBO, or an autoimmune disease - bc yes, those are connected and stomach issues left untreated will cause IBS or worse. I’ve been using this app for a few days and already I’ve gotten so much insight - I had no idea certain ingredients were triggering my gut. It looks like the first week is a calibration period - after 7 days of logging I’m going to get my first weekly report and I can’t wait!! I also love the daily wellness score and notification reminders to take my supplements. Definitely give it a try!! You won’t regret it
Developer Response
Bethany, you're right — bloating after every meal isn't normal, and catching yours this early is the whole game. Excited to hear about what other triggers you find as the app keeps calibrating to understand you better and better. Thank you for spreading the message!
Wish I had this years ago!

I’m not someone who usually leaves reviews but this app deserves it. I've been dealing with bloating and stomach issues on and off since college and I basically just accepted it as "my normal." Tried the low FODMAP diet on my own a couple of times but it's so overwhelming and I could never stick with the elimination phase long enough to figure out what was actually bothering me. Through this app I learned yogurt and hard cheeses were mostly fine, but milk in my coffee and cream-based sauces would wreck me the next morning. That kind of detail is something I never could have figured out from a generic avoid dairy list online.The app is clean and logging is fast which matters a lot because if it's annoying I wouldn’t do it. I've abandoned so many tracking apps because they make you enter every ingredient and I burn out.I used to cancel plans or call out of work at least once or twice a month because of my stomach. That's already costing me more than this app does. Genuinely worth trying for a month to see if it clicks for you!
Developer Response
Sarah this made my whole week! The milk-in-coffee detail is exactly the kind of thing no generic dairy list will ever catch, which is why we built it. And thank you for noticing the logging speed — that was the thing I obsessed over most hahah
Worth every penny!

Skeptical at first but the money back guarantee made me try it .. completed the 6 week program and it flagged 2 triggers I would have never found on my own (a protein bar I was eating daily and onions lol). AI chat is surprisingly helpful too, like having a personal gut health coach. Because of that, I canceled my nutritionist appointments which actually ends up saving me money. Definitely give it a try
Improved onboarding flow and UX!
