Food, diet, workouts, sleep and fluids all in one place — and, whenever you want, your labs and medications too. It's the 360 view no diet app gives you.

Food in one app, workout in another, sleep on the watch, labs in your email. None of them talk to each other — and the answer lives exactly at that intersection. Bad sleep tanks your workout, the workout changes your hunger, hunger changes your weight. On separate screens, you never see it.
A photo of your plate becomes calories and macros. Barcode for packaged food. A photo of your nutritionist's plan becomes a per-meal target — and the app shows your adherence to it, meal by meal.
A photo of your routine becomes a structured workout, with load, 1RM and rest timer. Cardio comes in with calories deducted from the day's goal.
Hours, quality and HRV. Water and other drinks by type. Weight and body composition — the calorie target adjusts itself as your real weight moves, instead of staying at a fixed number calculated once.
A daily dashboard, weekly trends and an on-demand analysis that reads every module at once. Not a per-screen summary — a read of the whole picture.
Insights reads your modules at once — food, workouts, sleep, weight, fasting, bloodwork, medications and whatever you reported feeling — and answers free-form questions. Not canned diet-app copy: a read of your own data, with the numbers behind it.
"Does my sleep get worse during heavy training weeks?"
"My ferritin dropped between two tests — what in my diet explains it?"
"I hit my calorie target all month and the scale did not move. What is going on?"
The analysis tracks a marker across tests over time, cross-checks a reported symptom against what changed in your routine, and takes medication in use into account. It describes what your data shows — and stops there: it does not diagnose, prescribe, or tell you to change a dose.
This is where Merid stops being a diet app. A photo or PDF of your labs becomes a historical series for each marker. What you take — supplement or medication — goes in the same place, with interactions between formulas. With that, the loop closes — what we call the Iron Protocol:
It doesn't recommend a dose, tell you to start or stop a medication, or claim causation. It shows the pattern, the sample size and the timeline. The decision is yours and your doctor's.

|---|---|---|
| Food, workout, sleep and fluids | each in its own app | one dashboard |
| Photo of your plate | separate paid plan | included |
| Calorie target | fixed, calculated once | adjusts to your real weight |
| Nutritionist's plan | don't have it | per-meal adherence |
| Intermittent fasting | just a timer | cross-referenced with sleep and HRV |
| Blood work | don't have it | series + retest timeline |
| Medication and interactions | don't have it | same place |
| Free-form questions | generic chatbot, blind to your history | reads every module of yours at once |
A plate photo and a lab report reading are estimates, not measurements. Merid treats both as drafts: nothing reaches your history without going through you.
Nothing saves itself. Whatever the AI read from a photo, a lab report or a spoken sentence shows up for you to fix before it becomes a record.
Missing stays missing. A nutrient the reading could not find stays unknown instead of becoming a zero that would quietly drag your average down.
Every micronutrient says where it came from: composition table, scanned label or AI estimate. You know which number to trust more.
No camera weighs what is on your plate. That is why the estimated portion is always editable, and the app would rather say it does not know than fill the gap with a confident guess.

Sign in with Google, with Apple or through an email link — no password to invent, no approval to wait for. The Free plan asks for no card, has no deadline, and already includes full manual logging plus twenty AI readings and two analyses a day. You decide whether paying is worth it after using it, not before.
Merid holds lab results, medication and glucose. That changes what the app may do with them — and what it never does.
Delete means delete. Removing your account removes the data for real, in a single operation: either all of it goes, or none of it does.
Consent per data type. Progress photos are only stored after you allow it, and revoking deletes the images right away.
Your data is not the product. Nothing is sold or shared with third parties for advertising, and the analysis exists for you, not for an advertiser.

No. Food, training, cardio, sleep, water and weight work on their own, and that is where most people stay. Blood work, medication and glucose are layers you switch on when you want — they make the app sharper, not necessary.
Yes, and the app says plainly when it does not yet have enough history to conclude something, instead of inventing an analysis from three days of data. The first readings show up in week one; the ones that cross modules need more history.
The crossing. A diet app counts calories; here the same week of food is read alongside your sleep, your training and — if you want — your latest blood work. That is the question no food diary answers on its own.
No, and it is built not to try. It does not prescribe a dose, a treatment, a fixed diet or a training load, and it does not claim causation. It shows the pattern in what you logged and, when the data calls for it, explicitly tells you to take it to a professional.
In our own database, tied to your account, and it is never sold or shared with third parties for advertising. You can request account and data deletion at any time — details in the privacy policy.
No. Everything can be logged by hand, and that is how the app was designed. If you have Apple Health or Health Connect, you can import sleep and exercise instead of typing.
