Log meals fast
Snap a photo, scan a packaged label, or type a dish. Minthe breaks it into the likely culprits and catches hidden triggers like inulin, onion powder, sorbitol, gums and emulsifiers.
For iPhone
Find what's really behind your bloating.
Bloating is rarely just one thing. Minthe helps you spot the foods, the timing, and the everyday stuff – stress, sleep, your cycle – that drive yours. No guilt, no streaks, nothing that scolds you.
Out now on the App Store. Free to log, always.
Three years of cutting things out, and you still do not know
This is the position almost everyone is in when they find us. Not "I need a food diary", but something more specific and more frustrating.
What you are doing now
- You react on Tuesday and not Thursday to the same meal, so nothing you conclude ever holds.
- Your diet keeps narrowing. Every bad week costs another food, and none of them ever come back.
- The app you tried recorded everything and concluded nothing, or handed you a score you had no way to check.
- You were told it is stress, which felt like being told to stop asking.
- Nine days in, you stopped logging, because nothing had come of the first eight.
What Minthe does about it
- Measures your own base rate first, so a bad Tuesday is compared against how often you get symptoms anyway.
- Tests suspects before you cut them, with repeated exposures and washout, so foods come back if they are innocent.
- Shows the working. Exposure counts, effect size, confidence interval, and "not enough data yet" when that is the truth.
- Treats stress, sleep and your cycle as drivers, so it can tell you when food is not the answer.
- Free to log, permanently, and an unlogged day counts as unknown rather than as a good day.
Everything the app does, feature by feature, with what is free and what is not.
What Minthe does
Log what you eat and how you feel. Minthe looks for patterns, tells you honestly how confident it is, then helps you actually test the ones that matter.
Track how you feel
Bloating, gas, pain, reflux, stool form on the Bristol scale and more, in a few taps. Severity reads as more or less, never good or bad.
Honest pattern finding
Real statistics: your own base rate, effect sizes, confidence intervals. It tells you when there isn't enough data yet, instead of a confident guess. See the method.
Gut-brain and cycle aware
Surfaces high-stress or poor-sleep days, and cycle-linked patterns, as drivers in their own right. Not just food, and not just as footnotes.
Test it, don't guess
Run a guided with-and-without test to check whether a suspected trigger, or a soothing food, really makes a difference for you.
Hidden ingredient scans
So a "natural flavors" label doesn't hide what sets you off. Minthe reads E-numbers and the aliases manufacturers hide behind. Browse the FODMAP food list free.
The loop that actually gets you an answer
Most tracking apps stop at "here's a correlation". A correlation is a hypothesis, not an answer. Minthe is built to close the loop.
-
Log
Meals and symptoms, quickly enough that you keep doing it. Skipping a day is fine: Minthe treats an unlogged day as unknown, never as "no symptoms".
-
Notice
Once there is genuinely enough data, Minthe surfaces a possible pattern, with how confident it is and what else was going on those days.
-
Test
You choose to test a suspect. Minthe schedules the challenge days and washouts, and works around what you have already logged.
-
Know
A result you can act on, or an honest "this one didn't hold up". Both are worth having.
Private by design
Your logs live on your device and sync only to your own private iCloud. We don't sell your data, show ads, or build advertising profiles. The only thing that leaves your device is an optional AI photo or label scan, and you choose when that happens. We keep the list of foods a scan identifies, not the photo itself. The privacy policy spells out exactly what that means.
Numbers, without the scolding
At setup you pick a focus. Gut health and symptoms keeps the calorie side out of the way; food and macros tracks intake, macros and weight against real targets, because a lot of people arrive here already counting and hiding the figure helps nobody. Either way the numbers are precise and the framing is flat: there are no streaks to break, going over a target is not a failure, and nothing in the app is designed to make you feel bad about a day you'd rather forget.
Even the severity scale is deliberately calm. A hard day shows as muted clay, not alarm red, because coloring every bad day in warning colors trains anxiety and reads as the app scolding you.
Common questions
Is Minthe a diet or calorie counting app?
It can count, if that is what you want from it. Minthe is built around relief and understanding, and it opens by asking which focus you want: gut health and symptoms, or food and macros. The second tracks calories, macros and weight against real targets. What you will not find on either setting is streaks, guilt states, or an app that treats a number it does not like as your failure.
How does Minthe work out my trigger foods?
It compares how often you get symptoms after eating a given food against your own personal base rate, then reports the risk ratio with a Wilson confidence interval. A suspect is only surfaced once it clears four gates: enough exposures, a large enough effect, an interval that excludes no-effect, and a real contrast against your base rate. It also corrects for testing many foods at once. The full method is published here.
Does Minthe diagnose IBS, SIBO or food intolerance?
No. Minthe is a wellness and self-tracking tool, not a medical device. It surfaces hypotheses to discuss with a clinician, never diagnoses. If you have red-flag symptoms it will tell you to seek medical care rather than keep tracking.
Where is my data stored?
Your logs live on your device and sync only to your own private iCloud. Minthe does not sell your data, show ads, or build advertising profiles. The only thing that leaves your device is an optional AI photo or label scan, and we keep the foods it identifies rather than the photo.
Do I have to pay to log my meals and symptoms?
No. Manual logging is free and unlimited, and always will be. Putting a paywall on basic tracking would starve the very data the pattern engine depends on. Paid tiers unlock AI scans, the correlation engine, guided food trials and lab test insights. See pricing.
Start with one week of logging
That is usually enough to see your own base rate, which is where every real answer starts.
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.
