A GLP-1 week has a shape — the dose, the days after it, the meals that go fine and the ones that don’t. Then the appointment arrives and none of it is where you can reach it.
What you can keep
Six things, five seconds each
- Doses
- Amounts and injection sites, on whatever rhythm you actually use — not a schedule the app decided for you.
- Symptoms
- What you felt and how strong it was, in your own words.
- Meals
- Descriptors like fried, dairy or spicy, so a meal takes one tap rather than a nutrition database.
- Weight
- Readings over time — typed once, or read from Apple Health if you turn that on.
- Mood & sleep
- A daily check-in for how you slept, how you felt and where your appetite was. Only if you feel like it.
- Notes
- A line of your own on any entry, so six weeks later you are reading a record rather than guessing.
Patterns
It notices. It doesn’t conclude.
Once there are a few weeks of entries, PlateCalm starts arranging them. Everything it shows you is a description of what you recorded — counts, orderings, coincidences in time. It never tells you a food brought on a symptom, because from a log alone, nobody can know that.
The dose week
One ring for where you are
One segment for each day counted since your last logged dose, with the dose itself at the top in apricot. A glance tells you where in the week you are without reading a date or doing arithmetic.
It counts days, not elapsed hours — a ring driven by time sits empty on dose day, which is exactly when you most want to see it full. And if your rhythm isn’t weekly, it follows the rhythm you actually log.
Which day tends to be busiest
Symptoms arranged by day of your cycle, so you can see whether day two has been consistently heavier than day five.
Descriptors that recur
Meal descriptors that have shown up near a rough patch in your own entries — noticed and shown, never blamed.
Weight against dose steps
Your readings plotted alongside each change in dose, so the two are readable together.
Calmer windows
The days and descriptors your own log has been quietest around.
How sure it says it is
Every pattern arrives with its own confidence
A week of entries is not six months of them, and PlateCalm says so rather than dressing a coincidence up as a finding. The first rung is an admission, and most patterns start there.

Menu Lens
Eating out, checked against your own history
Paste tonight’s menu. Each dish is read against the descriptors you have logged before, and comes back as one of three things.
Where “for you” means exactly that. There is no nutrition database behind it and no general advice about what anyone should eat — it is your own record, turned around and pointed at tonight’s menu.
Every comparison is worked out on the phone. The menu you paste is never uploaded.
Appointments
Arrive with the facts
Instead of trying to remember six weeks in the ninety seconds you get, hand over a page that already says it.
- Doses & changesEvery dose you logged, and where the amount changed.
- Symptoms by cycle dayArranged against the dose week rather than the calendar.
- Weight & nutritionReadings and averages over the window you chose.
- Your questionsThe things you wanted to ask, written down before you forgot them.
Choose the window — seven days, a fortnight, a month, or dates you pick — and which sections to include. Your notes and weight are always optional.
Three CSV exports of your raw entries come with the free plan, and Pro lifts the limit. Either way, nothing you logged is ever locked away from you — the file is the convenience, not the access.
Privacy
Your health data stays yours
Everything you record lives in PlateCalm’s private storage on your device, behind your passcode, with an optional Face ID lock on top. This is not a policy we promise to keep — it is how the app is built. There is no server of ours for it to reach.
No account
Nothing to sign up for, so there is no profile of you to hold in the first place.
No analytics
No usage tracking, no advertising identifiers, no third-party ad SDKs. None.
Nothing sold
There is no copy of your log anywhere but your phone, so there is nothing to sell.
You choose what leaves
A report leaves only when you send it, through the iOS share sheet, to a destination you pick.
The one exception, stated plainly: subscription status is processed by Apple and RevenueCat. No health data is attached to it.
Pricing
Free to keep your record. Pro to read it back.

The three free CSV exports are a lifetime allowance rather than a monthly one, and only a share that finishes is counted — backing out of the share sheet costs nothing. Nothing is ever withheld from you inside the app: every entry stays readable whether or not you have exports left. Pro removes the limit.
Subscriptions renew automatically until cancelled, and are managed in your Apple ID settings. Full subscription terms.
A note on what this isn’t
PlateCalm records what you log and nothing more.
It never says a food brought on a symptom, never recommends a dose, an amount or a schedule, and never predicts how a change will feel. Reminders are reminders to log, not to dose. It is not a medical device and it does not give medical advice.
Those are conversations for you and your clinician. This just makes sure you arrive with the facts.
Track what happens.
See what repeats.
Bring the facts with you.
