Free scheduling service Test kits sold separately

App Dependency Depends on the app. This page describes how the P in the Cup app is intended to work. The app is not live yet, and details may change before launch.

Parents & Families

Rebuild trust through clear expectations, not repeated accusations

When an adult in your family has agreed to voluntary testing, the hardest part is often not the test. It is the argument about when, who decided, and whether it was fair. P in the Cup lets an independent schedule choose the days, so the conversation can move on to support.

The random scheduling and accountability service is free. Test kits and any laboratory testing are purchased separately.

Who this page is for

P in the Cup is for consenting adults. Every participant chooses to join, can see the terms they are agreeing to, and can leave. It is not a tool for monitoring a child, checking up on someone who has not agreed, or enforcing rules on another person.

The problem we are trying to remove

Why "who picks the day" causes so much friction

Many families describe the same pattern. One person chooses a test day, the other feels singled out, and the result, whatever it is, gets lost in an argument about motive.

"Why today?"

When a family member chooses the day, it can feel like a reaction to a mood, a late night or a disagreement. That suspicion is hard to answer.

Uneven power

If one person always decides, the other can feel watched rather than trusted. That works against the reason you agreed to this in the first place.

Conversations that go sideways

Arguments about the process crowd out the conversations that matter: how someone is doing, what is going well, and what support would help.

How a neutral schedule helps

Agree the rules once, then let the schedule decide

  1. Talk it through and agree together

    Decide how often a test day might come up, what "taking part" means, and what each person will see. Nothing starts until everyone has accepted the agreement.

  2. The schedule is chosen in advance

    Test days are selected on the app server ahead of time, not by anyone in the family and not by pressing a button. Checking "Is today the day?" only reveals what was already decided. Read more on fair random scheduling.

  3. Follow through as agreed

    On a scheduled day, the participant uses a separately purchased home or professional test, as you agreed. Reporting completion is optional and depends on your agreement.

  4. Notice the effort

    Recognition is for participation and consistency: showing up, checking in, keeping a streak going. It is never a reward for a particular test result.

What is free, and what is not

The random scheduling and accountability service is free. Test kits and any laboratory testing are purchased separately. P in the Cup does not sell or administer tests. See the Test Kit Guide for neutral buying education.

Starting the conversation

How to propose an agreement respectfully

The way you raise the idea matters as much as the tool. A few principles many families find helpful:

  • Pick a calm moment, not the middle of a disagreement or right after an incident.
  • Frame it as something you build together: "Could a fair, random schedule make this easier for both of us?" rather than "You are going to be tested."
  • Invite the other person to shape the terms: how often, which kind of test, what gets shared and with whom.
  • Be clear about what you will do with the information, and what you will not do.
  • Agree in advance how you will talk about a result you were not hoping for, including that a home screen is preliminary and may need laboratory confirmation.
  • Agree a date to review the arrangement, and say plainly that either of you can pause or end it.
  • If the answer is no, respect it. A schedule that someone has not freely agreed to is not what this service is for.

Home tests have limits

The U.S. Food and Drug Administration advises that a preliminary positive home test should be sent to a laboratory for confirmation and that no serious action should be taken until the laboratory result is known. It also notes that no test of this type is 100% accurate and a negative does not rule out drug use. Read more in how to choose a test kit.

Consent and control

Voluntary from start to finish

Everyone agrees, everyone can see the terms

An agreement explains which fields other participants may see before anyone accepts it. No one is added to a schedule without accepting.

Share only what you approve

Each person chooses what to share. Schedule-only mode lets you use the schedule without recording any test outcomes at all. See Privacy Explained.

The ability to leave

Any participant can withdraw from an agreement or leave a group. An arrangement that cannot be left is not a voluntary one.

Support, not surveillance

P in the Cup is not a monitoring, discipline or punishment tool. It gives no location tracking, no secret checks, and no way to watch someone who has not agreed.

The P in the Cup app is launching soon and is not yet available. Features described here reflect the planned design; see How It Works and FAQ for current status.

Encouragement without shaming

Celebrate follow-through, not perfection

A schedule is a structure, not a verdict on someone's character. The language you use around it can rebuild trust or wear it down.

  • Recognise effort. "Thanks for checking in today" says more than silence on a good day and a lecture on a hard one.
  • Separate the person from the result. A preliminary screen is information to talk about calmly, not proof of anything on its own.
  • Avoid labels. Words like "clean" and "dirty" carry judgment. Talk about agreements, check-ins and goals instead.
  • Keep the schedule out of every conversation. Let it do its job so the rest of your relationship does not revolve around it.
  • Look after yourself too. Family members carry stress. Support for you is worth seeking in its own right; our Trust & Support Library lists organisation-agnostic places to start.

P in the Cup does not promise sobriety, and a run of negative screens does not guarantee it. What the service can do is make expectations explicit and take one recurring argument off the table.

An illustration

What this can look like

Example persona

"Dana" and her adult son "Leo"

This is a fictional example, not a real customer. Leo, 24, has offered to do voluntary testing while he rebuilds trust with his mother. They used to argue every time Dana suggested a day. Together they agree on a schedule of roughly one test day a week, chosen in advance by the service. Leo shares only whether he completed a scheduled check-in, not any result. Dana agrees not to ask for extra tests outside the schedule. Both can see the terms, and they plan to review the arrangement after a month. Leo buys his own test kits; the schedule itself costs nothing.
