Shared bottles, shared meds: how to track a bottle more than one person takes
NestBoard · 2026-05-19
The model that does not fit the counter
Imagine two people who both take magnesium from the same bottle. Under a one-person-one-bottle model, tracking that means logging two separate 60-capsule containers for what is, in the kitchen, a single bottle. Duplicate the entry and pretend there are two bottles.
Which is silly, because there is one bottle on the counter and both of them reach for it. When it gets low, one of them reorders. That is one bottle serving two schedules, and a per-person model insists it is two bottles serving one each.
NestBoard models it the other way round, on a parent record: one entry for the physical bottle, with a name, dosage, form, and dose count tracked on the bottle itself. Each person who takes that medication gets their own schedule attached to it. One magnesium capsule before bed for one person, one in the morning for the other. Different times, same bottle.
One bottle, one shared supply
If three people in a house take the same vitamin D supplement, they are all pulling from one bottle on the counter. Three separate supply counts for one jar is not a useful picture of anything.
That is how shared bottles work in NestBoard. The supply is tracked at the bottle level, not the person level. Everyone assigned still logs their own dose, and every log draws that one shared count down by one, so the number on the shelf and the number in the app stay together. If the bottle started with sixty capsules and two of you took one today, it shows fifty-eight remaining. The math works the way the cabinet works.
How to set up a shared bottle
The easiest way is when you first add the medication. Pick the person taking it, fill in the name and dosage and schedule as usual, then use "Share this bottle with" and tap each additional household member who takes from the same bottle. Save, and you are done.
If the medication already exists, tap "+ Add person" on its card. This opens a small window that only asks who the new person is and when they take it. The bottle details like name, dosage, form, and doses per bottle are already set, so the new person inherits them automatically.
Either way, the bottle is shared. Whenever anyone on that bottle logs a dose, the doses-remaining count goes down by one. The supply stays accurate no matter who took the dose.
Logging a dose from a shared bottle
When a dose is due for anyone on the bottle, that person's card and the "Today's doses" panel show a "Log dose" button. Tap it, confirm the time, and mark it given. The shared count drops by one the moment you do, no matter whose dose it was.
Forgot to log one earlier? Missed doses stay in today's list with their own "Log dose" button, and the time defaults to the original scheduled slot so the history reads the way it happened. You can also tell Robin ("I just gave Mia her ibuprofen") and it logs the dose exactly like tapping the button. Later, "who gave Mia her medicine this morning?" is answered from the actual dose log.
Reminders reach everyone
Dose reminders go to every person sharing the bottle, plus the family hub device. So if one partner usually handles the morning vitamin but is traveling, the other partner still gets the nudge. Whoever is home that day sees the reminder.
This works well for couples, but also for things like a shared probiotic for kids, or a household iron supplement that a few family members are taking together. The bottle knows all of them, and the count reflects reality.
For the doses that genuinely cannot slip, event and medication alarms ring a real alarm with sound instead of a notification that waits to be noticed.
Supply tracking with shared bottles
NestBoard counts in doses, not pills. A dose is one time the medication is taken, not one pill. If a single dose is two pills and the bottle holds sixty pills, that is thirty doses total.
When you turn on supply tracking, there is a little calculator under "Count in pills? We'll do the math." Enter how many pills are in the bottle and how many pills are in one dose. It shows the result, like sixty pills at two per dose equals thirty doses. Tap "Use this" and it fills both supply fields for a full bottle.
Once you have set a remaining count, each medication card shows a small chip like "30 doses left." When the med also has scheduled times, the chip adds an estimate of how many days of supply that is, based on the scheduled doses per day of everyone on the bottle, so every card on a shared bottle shows the same estimate. As-needed doses are not on a schedule, so they are not part of it. Someone you only tap under "Share this bottle with" has no schedule of their own, so the estimate cannot count their doses ahead of time. If they take it on a set schedule, add them with "+ Add person" instead.
When doses remaining drops to a few left, the household gets a "Refill soon" notification. It sends once per bottle, then re-arms after you refill by raising the doses-remaining count back up. The notification respects quiet hours, so it never pings overnight.
You can also ask Robin "are any meds running low?" and it reads back every med with a supply count, lowest days of supply first.
Why the count lives on the bottle, not the person
A per-person supply count works fine for prescriptions at different dosages, where each person really does have their own bottle. It breaks down for the things a household shares: multivitamins, vitamin D, fish oil, probiotics.
In real life, one person opens the bottle in the morning, shakes out four capsules, and hands them around. The bottle goes back on the shelf. If every person kept a totally separate count for the same jar, the numbers would drift apart fast, and nobody would trust what the app said was left. Tie every dose to one shared supply and the count stays honest no matter who reached for the bottle.
Stale reminders are handled separately from the bottle model, and worth knowing about: when you open or return to the app, NestBoard clears any dose reminder that is no longer pending, so a dose someone else already logged does not sit in your tray looking undone.
When individual tracking still matters
Per-person tracking is still there by default. Each person keeps their own dose schedule and logs their own doses, so you can see who took what and review it over time. What the bottle shares is the supply.
Shared bottles are the right fit when the medication or supplement is genuinely the same supply. Two adults on the same multivitamin. Two parents alternating who gives the toddler their probiotic drops. Housemates sharing a bottle of ibuprofen. A parent and teenager both on the same allergy med through pollen season.
They are not the right fit when two people take the same drug at different dosages or from separate bottles. In that case, add two medications. Each has its own supply tracking and the counts stay independent, so you get individual refill warnings.
One edge worth naming: a shared bottle gets awkward when one person pauses their schedule, because they ran out of refills or the doctor said to stop for a while. The bottle keeps decrementing as long as anyone is still taking from it, which is the right answer for the supply count even though the pause is invisible on the bottle itself. If that bites you, the Feedback button reaches a person. On a phone it sits under More, and on a computer or tablet at the bottom of the left sidebar.
Where to find it
On a phone, tap More in the bottom bar, then Medical. On a computer or tablet, look under Life in the left sidebar and click Medical. If Medical is not in your sidebar, it is switched off, either for the whole household under Settings, then Modules, or just for your account under Settings, then Menu Visibility.

Frequently asked questions
How do I track a medication bottle that two people share? Add the medication once, then tap "+ Add person" on its card for each other person who takes from it. Every person keeps their own schedule, and every dose anyone logs draws down the one shared supply count, so the number in the app matches the pills on the shelf.
Does each person still get their own reminders? Yes. Dose reminders go to every person sharing the bottle and to the family hub device, and each person logs their own dose, so the history still shows who took what and when.
What happens to the supply count when someone else logs the dose? It drops by one, the same as if you had logged it yourself. The count belongs to the bottle rather than to any one person, which is why it stays accurate when several people are reaching for the same jar.
When should I not share a bottle? When two people take the same drug at different dosages, or from physically separate bottles. Add two medications instead so each keeps its own supply count and its own refill warning.
