Minthe vs Nerva
Choose Nerva if
- You want a treatment, not a measurement.
- You have already eliminated a lot of foods and it has not helped.
- Your symptoms flare with stress in a way that food alone does not explain.
- You want an approach with clinical trial support behind the mechanism.
- You want something structured and finite: about 15 minutes a day for six weeks.
- You use Android. Nerva is on both platforms. Minthe is iPhone only.
Choose Minthe if
- You do not yet know whether food is involved, and want that answered properly.
- You want your own base rate established before anyone draws a conclusion.
- You want to know how a finding was reached before you act on it.
- You want stress, sleep and cycle measured alongside food rather than assumed.
- You want to reintroduce foods you cut without a clear reason.
Where Nerva is genuinely better
- It treats something. Minthe does not. This is the fundamental one. Minthe produces information. Nerva runs an intervention with a plausible mechanism and a research base. Information is only worth having if you act on it, and for a lot of people the action is exactly what Nerva offers.
- The mechanism it targets is real and widely under-treated. Visceral hypersensitivity, where normal gut sensation is read as pain, is a well described feature of disorders of gut-brain interaction. No amount of food logging fixes it.
- Its critique of food-hunting deserves to be taken seriously. Nerva argue that people spend years eliminating foods down a path that misses the driver. We have seen enough over-restricted diets to agree that this happens often, and an app that only ever looks at food would quietly make it worse.
- Track record on both platforms. Live since 2019, with 14,854 US ratings averaging 4.7, on iPhone and Android. Minthe launched in 2026, on iPhone only.
Where the two actually meet
The disagreement is smaller than it looks. Nerva’s argument is that food is often not the driver. Ours is that you cannot know which case you are in without measuring, and that most people have never measured. Both of those can be true at once.
The practical failure mode Nerva describes, years of elimination that narrows the diet without resolving anything, is usually a failure of method rather than a failure of looking at food. Cutting a food, feeling better for a week, and keeping it out forever is not a test. It has no control, no baseline, and no accounting for the fact that symptoms fluctuate on their own. That method produces a smaller diet and no knowledge, which is precisely the outcome Nerva is objecting to.
Minthe is built the other way round. It establishes what your symptom rate is in general before making claims about any food, corrects for the fact that testing many foods at once manufactures false positives, refuses to surface anything that has not cleared four separate gates, and says "not enough data yet" rather than guessing. A tool built like that can return the answer "food does not appear to explain this", and that answer is the one that should send you to something like Nerva.
| Nerva | Minthe | |
|---|---|---|
| What it is | Gut-directed hypnotherapy program for IBS, functional dyspepsia, reflux and bloating | Symptom and food tracker with a statistical trigger engine |
| Approach | Treatment. A 6-week program, about 15 minutes a day, then a maintenance plan | Measurement. No treatment component |
| Targets | Gut-brain hypersensitivity | Food, timing and daily-life drivers |
| Price | $199/year in the US after a 7-day trial ($149.25 with a provider referral) | $6.99/month or $39.99/year. Elite $59.99/year for more scans. |
| Free tier | None. 7-day free trial | Unlimited manual logging, free forever. Barcode lookup free, 7 AI scans at install then 3 a week. CSV and PDF export included. |
| Platform | iPhone and Android | iPhone only, iOS 18 or later. No Android, no web. The app is in English. |
| Food logging | Not the point of the app | Yes: photo, barcode, label scan or typed |
| Your own base rate | Not applicable, it is a therapy program | Yes. Every result is contrasted against your own base rate. |
| Statistical method | Not applicable, it is not an analysis tool | Yes, in plain English at /method. |
| Confirmation testing | Not applicable, it is a therapy program | Yes. Guided with-and-without tests, days picked at random in advance, with washout. |
| Non-food drivers | Stress and the nervous system are the entire focus | Sleep, stress, menstrual cycle, water and alcohol, each taken out as a confounder. Apple Health read and write. |
| Evidence base | Gut-directed hypnotherapy has clinical trial support for IBS. Nerva cites a Monash University trial of its own program | Published method, no clinical trials of the app itself |
| Track record | On the App Store since 2019, 14,854 US ratings averaging 4.7 | Launched August 2026. No long track record yet. |
Checked September 2026. "Not verified" means we could not confirm it from public sources, not that the feature is missing.
Using both, which is the honest recommendation
-
Log until you have a base rate before deciding anything
There is no fixed number of days: you need enough logged days for Minthe to know how often you get symptoms anyway plus enough meals with a given food to compare against it. Logging is free in Minthe. It is the only way to find out which problem you actually have. Reading the patterns is the paid part.
-
If food explains a meaningful part of it, test the suspects
Confirm with controlled exposures rather than adopting a permanent restriction on the strength of one bad week.
-
If it does not, stop looking at food and treat the axis
This is the case Nerva is built for. Logging through the program is still worth doing, because it tells you whether the treatment moved your symptom rate against a baseline you already have, rather than against how you remember feeling.
Not comparing against Minthe? Nerva vs Monash FODMAP, with Minthe left out of the table.
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 difference between Nerva and Minthe?
They disagree about the problem. Nerva treats gut-brain hypersensitivity with a structured program of gut-directed hypnotherapy, on the view that for many people with IBS the nervous system is the driver and food-hunting is a distraction. Minthe measures whether food and daily factors actually track your symptoms. One is a treatment, the other is a measurement. Neither is a substitute for the other.
Is Nerva evidence-based?
Gut-directed hypnotherapy has a real research base for IBS, and it is recommended in several clinical guidelines as a psychological therapy option. That is a stronger evidence position than most apps in this category can claim, and it is why we do not treat Nerva as a competitor to argue with so much as a different thing to do.
How do I know whether my symptoms are food-driven?
By measuring, which is the honest answer and also the one that favours us, so weigh it accordingly. Most people have never established their own base rate, so they do not know how often they get symptoms in general, which makes any impression about a specific food unreliable. Minthe is built to report that food does not explain your pattern when that is what the data says. That result is genuinely useful, because it points you toward gut-brain approaches like Nerva instead.
Can I use both?
Yes, and it is a sensible combination. They do not interfere: one is a six-week program of daily sessions of about 15 minutes, the other is logging. If you are going to do a hypnotherapy program it is worth logging through it, because you then find out whether it worked against your own baseline rather than by recollection. On cost, Nerva is $199 a year in the US after a 7-day trial, with no free tier; Minthe’s logging is free and its analysis is $39.99 a year.
Which should I start with?
If you have already cut out a lot of foods and nothing has helped, start with Nerva. That pattern is exactly what it is designed for and more food-hunting is unlikely to be the answer. If you have never systematically measured anything and your symptoms seem to come and go, start by measuring, because you are otherwise guessing at which category you are in.
