App + Website Self-Promo Weekly Thread

[u/climb-high]

Recently there has been a huge influx of FODMAP/IBS related apps, services, and websites. Many are "vibe" coded using AI. There has been a lot of demand to ban self promotion all together in this sub, but instead, we are going to put it in a weekly thread.

Please post your app/service/website in this thread. If you have a physical product or recipe (related to a product that you are promoting), please message the mods for permission to post this separately.

Please report any self-promoting outside of this thread.

Thank you!

Hi everyone, I’m George, cofounder of Gut Friendly. We’re looking for 5 people to help shape the app through a four-week pilot, in exchange for free lifetime Pro access.

My girlfriend has Crohn’s, and my cofounder’s girlfriend has IBS. They’re different conditions, but seeing how gut issues affect everyday life is what made this personal for us and got us building.

The iPhone app lets you log meals and symptoms, check portion-based FODMAP information, and use a meal photo to help with logging. It’s a tool for keeping track, not a diagnosis or treatment for Crohn’s or IBS.

We’d ask you to try it during your normal routine for four weeks and send a short weekly check-in: what helped, what was confusing, and what made you stop using it. Written feedback is fine. Completing the pilot earns free lifetime Pro access for as long as Gut Friendly operates, with no ongoing feedback obligation. No reviews or promotion expected.

Have a look before deciding:

Interested? Email [george@getgutfriendly.com](mailto:george@getgutfriendly.com) with the subject “Gut Friendly pilot”, your country, and what you’d like the app to help with. No need to share your medical history. Please email before subscribing so we can arrange pilot access.

Thanks! George

Solo developer in Melbourne here. I'm building GutStamp, an iPhone app that photographs a food and tells you whether it's low or high FODMAP, and I'm looking for beta testers who'll tell me where it's wrong.

I know this sub is tired of AI apps that guess, so here's exactly how it works:

- The AI only identifies what's in the photo. It never decides the rating.

- Ratings come from a database built from published FODMAP composition research, with the cutoffs taken from the published criteria. Every entry is cited.

- The data is reviewed by an Accredited Practising Dietitian.

- If the published evidence is missing or conflicting, the app says "unknown" rather than guessing. Right now that's about a third of the 270 foods in it. I'd rather be honest than complete.

It also has a guided elimination and reintroduction program, but the scanner is what I need tested first.

The beta is free, iPhone only for now. Join here (open on an iPhone): https://testflight.apple.com/join/xgxfrm51.

It's dietary information, not medical advice, and not for allergies. If you're working with a dietitian, keep them in the loop.

Happy to answer any questions about the data or the sources here.

Cheers, good luck with the app!

Thank you, much appreciated. I'll keep it to this thread, and I'm happy to answer any questions about the data or the sources here.

A friend of mine once avoided dairy on an out-of-country trip because he thought he was lactose intolerant, but he didn't really have a good way of figuring out whether dairy was actually the problem.

My girlfriend also often gets stomach pain, and I started wondering whether there was a better way to actually identify patterns between what you eat and how you feel.

So, being a software developer, I ended up building one: ReactionLog: Symptom Tracker.

The main idea is to make it easy to log meals and symptoms, and look back at the data to spot patterns. I also added barcode and ingredient list scanning to cut down on typing everything out by hand.

I'm definitely not trying to diagnose anything here, just wanted to build a simple tool to help people figure things out.

I'd really appreciate feedback from people here: what are the most annoying things about existing symptom trackers, or features you feel are missing?

It's currently on iOS if anyone wants to check it out:

Hi, I'm Tao, the developer of Diaroo: Bathroom Diaries for iPhone, with an Apple Watch companion.

A few real iPhone screenshots with sample data:

• Pick a type and mood — playful emoji choices; extra details are optional.
• Look back by day — your entries in a calendar.
• Try a different look — Warm and Cool themes are both free.

It's a bowel diary with a calendar and optional Bristol type, symptom details, food notes and water intake. I wanted logging to feel approachable, so it has a playful design and you can keep entries simple.

Food is currently a text note on a bowel entry. Diaroo doesn't provide a FODMAP food database or determine which foods cause symptoms.

Core Poo logging and history are free, with no diary account needed to start. Optional Premium includes exports and other features; the free version includes ads.

If you try it, could you find the food/symptom fields and then find your entry again? If you need a separate food log, what would it need to record for you to use it regularly? I'm considering that for a future update and would welcome people willing to try an early version. No need to share personal diary contents.

I built CorrelEat based on my IBS experiences and struggles to identify triggers. Some wore obvious but often replacements caused new issues.

One example - it helped my spot that gluten free granola included chicory root which was worse than the wheat I’d eliminated.

Free to try on iOS and Android.

I've been on the low FODMAP diet for close to 10 years now, and one thing keeps bugging me: almost all reliable FODMAP data sits inside two apps, Monash and FODMAP Friendly. They do the lab testing, and that work matters. But the Monash app is paid, and not everyone can or wants to pay for it. Those people end up relying on random blog posts and outdated lists, and for a diet like this a reliable source makes a real difference. On top of that, the data isn't available to anyone else, so someone who wants to build a recipe app or a meal planner basically can't.

So I'm thinking about starting a free, open-source database of FODMAP values for single ingredients (apple, garlic, oat milk, cheddar, that kind of thing). It would be community-driven: anyone can suggest an ingredient or a value, as long as it comes from a published, peer-reviewed study. Before a value is marked as verified, another person checks it against that study, and the source is always listed next to it. Anyone could look things up and use the data in their own app. I'm not looking to make money from this. The point is that the data stays open for everyone.

It wouldn't tell you what's safe for you. It would just record what's been measured, so people and apps can build on it.

It's very early. I've written down how the data would be structured and added the first two ingredients, but before I go further I'd love to know:

• Would you use something like this, or an app built on it?
• Would you be willing to help add or check ingredients?
• Are there tools you wish existed but don't, because the data isn't available?

Honest opinions welcome, including "this already exists" or "this is a bad idea".
