Rumbelly vs FODMAP Snap
Updated August 2026
Both apps use AI to flag FODMAP triggers — the carbs in onion, garlic and wheat behind bloating — in your food. Here is an honest, side-by-side comparison, including where FODMAP Snap is genuinely good, so you can choose what fits your gut and your budget.
| Feature | Rumbelly | FODMAP Snap |
|---|---|---|
| Free every day | 4 AI scans a day, free — plus unlimited manual meal logging. No paywall just to use it. | About 3 AI scans a day on the free tier; most features need Pro. |
| Do edits cost a scan? | No. Editing a meal never spends one of your scans. | Yes — editing a logged meal uses up one of the daily scans (developer-confirmed). |
| Privacy & independence | No ads, no food-industry money, and your photos are analysed but not stored by us. | No privacy or independence claim in the App Store listing. |
| How triggers are judged | Based on the low-FODMAP approach developed at Monash University; says “uncertain” instead of guessing. | AI trigger detection; some reviews report misclassified foods. |
| Eating out & menus | Built to scan real meals and restaurant menus for hidden onion and garlic. | Has a “Quick Check” restaurant and grocery lookup. |
| Price | Premium is €29.99/year or €4.99/month. | Pro is around $40/year (several price points shown). |
| Focus | A focused, independent gut-health app. | One app inside a multi-diet studio portfolio. |
Where FODMAP Snap is genuinely good
FODMAP Snap is a capable, actively updated app: 13 languages, a developer who replies to almost every review, and a broad feature set (SIBO mode, recipes, PDF export, mood tracking). If you want the widest features in one place and do not mind paying yearly, it is a solid choice.
Which should you choose?
Want the most features in one app? FODMAP Snap is strong. Want to try before you pay, keep your data private, and catch the hidden triggers that ruin eating out — without edits eating your daily scans? That is exactly what Rumbelly is built for.
