The best food diary apps, compared by how much work they are
Sorted by how much work they ask of you
| App | Effort per entry | What you get back | Export |
|---|---|---|---|
| Bowelle | Lowest. Quick taps, minimal fields | Trends and a clear history | not verified |
| Bearable | Low to moderate, and you choose what to track | Correlations across everything you log, not just food | not verified |
| Minthe | Moderate. Photo, barcode, label scan or typed | Named suspects, with how many meals each is based on and how sure it is | CSV and clinician PDF, free |
| Gutsy | Moderate. Photo or barcode, plus stool, water and supplements | Trigger candidates with confidence levels, a daily 0–100 wellness score | Doctor PDF, CSV and JSON |
| mySymptoms | Highest. Detailed entries, with food search and barcode scan | Correlation reports with histograms and trend charts | PDF and CSV |
| Fig | n/a. It is a scanner, not a diary | Whether a product fits your restrictions | n/a |
| Macro trackers: MyFitnessPal, Cronometer, MacroFactor | Low to moderate. Huge food databases, barcode and photo logging | Calories, macros and trends. Their listings describe no analysis of which foods drive a symptom | Varies |
Checked September 2026. "Not verified" means we could not confirm it from public sources, not that the feature is missing.
The three things that decide whether a diary is any use
1. What happens on the days you do not log
This is the most consequential design decision in a food diary and almost nobody asks about it. If an app treats a missing day as a day without symptoms, every gap quietly drags your apparent symptom rate down, which makes real triggers harder to detect and can manufacture false ones. The correct handling is to treat an unlogged day as unknown and exclude it. Minthe does that and says so; for the others we could not confirm the behavior from public sources, which is why the rows above read "not verified" rather than "no".
2. Whether it corrects for looking at many foods at once
A diary with fifty distinct foods in it is running fifty comparisons. At a conventional threshold, two or three will look meaningful by pure chance even if none of them affect you. Any app that surfaces "your triggers" from a long food list without correcting for this will hand you confident-sounding false positives, and you will then remove foods you did not need to remove. Minthe checks every result against that risk. Here is how it works.
3. Whether a clinician can read the output
A gastroenterologist has minutes, not an evening. Screenshots of an app's dashboard are close to useless in an appointment; a dated summary of symptom frequency, severity and what changed is not. This is worth checking before you invest weeks of logging in something. What a food diary should actually show your doctor covers what to bring.
If you are choosing right now
Start with the lowest-effort option that records what you need. You can always move: your history is the asset, and an app that exports it is one you can leave. If you already know you are the kind of person who logs thoroughly, the more detailed tools reward that. If you know you are not, be honest about it and pick accordingly, because the alternative is not a better diary, it is no diary.
If your food diary is already a calorie counter
Plenty of people with bloating already log every meal, in MyFitnessPal, Cronometer or MacroFactor and still cannot say which food is the problem. That is not a failing of those apps. A calorie counter records what you ate and totals it; it does not compare your symptom days against your other days. Each of our macro-tracker pages says plainly who should keep their tracker, who might switch and who could run both: vs MyFitnessPal, vs Cronometer and vs MacroFactor.
Already using one of these?
Switching is a different question from choosing. These cover what actually transfers, what does not, and the cases where staying put is the right answer.
- Cara Care alternatives, sorted by the reason people leave: cost, stability, or wanting analysis rather than a program.
- Bearable alternatives, for when a general symptom tracker is not specific enough about your gut.
- Monash FODMAP alternatives, including the free lookup tools, and when to just buy Monash.
The other roundups
Each of these sorts the category on a different axis, because ranking the same apps four times in the same order would be one page with four URLs.
- Best bloating trackers, sorted by which problem you have.
- Best IBS apps, sorted by learn, treat or measure.
- Best low FODMAP apps, sorted by where the data comes from.
How apps get on this page. They have to be live on the US App Store, be findable by someone searching for this problem, and do the job the page is about. We include apps that beat Minthe, and we say where they beat it. No app pays to be here and there are no affiliate links on this page.
What changed in this update. Re-checked every app on 29 September 2026. mySymptoms is subscription-only after a 7-day trial and now has barcode scanning; the 1 to 72 hour analysis window we used to list could not be sourced and has been removed. Added Gutsy and a row for the macro trackers. First published September 2026, sorted by logging effort rather than by feature count, because adherence is the variable that decides whether any of these produce an answer.
Minthe is a wellness and self-tracking tool, not a medical device. It does not diagnose or treat any condition and isn't a substitute for professional medical advice. If you have red-flag symptoms such as blood in your stool, unintentional weight loss, difficulty swallowing, persistent vomiting or a fever alongside gut symptoms, see a clinician rather than tracking them.
Frequently asked
What is the best food diary app for finding intolerances?
For depth and flexibility, mySymptoms, which has been doing this since 2010 and shows its correlation reports as histograms you can inspect. For breadth across several conditions, Bearable. For the least effort, Bowelle. If you already log everything in a calorie counter such as MyFitnessPal or Cronometer, keep it for the numbers: none of their listings describes working out which foods drive a symptom. For statistical rigour and a confirmation step, Minthe, which we make. The honest answer is that the best one is whichever you will still be using in three weeks, because none of them can analyze data you did not log.
How long do I need to keep a food diary?
There is no fixed timeline, because a conclusion needs a condition rather than a date. Every useful question is comparative: to know whether a food raises your symptom risk, the app first has to know what your symptom risk is in general, which takes enough logged days. It also needs enough separate meals with that food. A food you eat most days gets there much sooner than one you have once a month. That baseline is the thing people underestimate, and it is why diaries abandoned at day nine produce nothing.
Do I have to log every single meal?
No, and any app that depends on it is badly designed, because nobody sustains that. What matters is how gaps are handled. A day you did not log should be treated as unknown, not as a day without symptoms, because scoring gaps as symptom-free quietly biases every result. Minthe treats them as unknown; for the other apps we could not confirm the behavior from public sources.
Can I export my food diary for a doctor?
mySymptoms and Minthe both export. mySymptoms also has a web Clinic app your clinician can use. Minthe produces a CSV of raw logs and a clinician-oriented PDF summary, both free, plus an IBS-SSS severity score which is a published instrument your clinician may already recognize. Check the export format before you rely on it: a screenshot dump is not the same as something a gastroenterologist can read in two minutes.
Is a paper diary just as good?
For the logging, honestly, often yes, and if paper is what you will actually keep then keep paper. What paper cannot do is the comparison: working out your base rate, counting exposures per food, correcting for the fact that examining fifty foods at once produces false positives by chance. That arithmetic is the only thing an app genuinely adds.
