Five steps, no arguments about the date
How P in the Cup works
You agree on the rules together. A schedule chosen in advance picks the days. You check whether today is one of them, follow through the way you agreed, and celebrate the effort. That's it.
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, supply or administer tests.
The app is launching soon
The P in the Cup app is still being built and is not open yet. This page describes how it is designed to work. Details may change before launch, and we will update this page when they do.
The five steps
From "who picks the day?" to "the schedule already did"
Every step is voluntary, and each person decides what they are comfortable sharing.
-
Agree on how often
Start a free account on your own, with one other consenting adult, or as a private group. Then agree on the basics: roughly how often a test day should come up (for example, about once a week or a few times a month), what each person will do on a scheduled day, and what, if anything, gets shared. Writing it down up front means nobody has to renegotiate it in the moment.
-
A random schedule is chosen in advance
Once the agreement is in place, the app draws the schedule on its server at the agreed frequency. Each day's status is settled before that day begins. Nobody in the agreement picks the days, and nobody can change them by clicking a button. Read how fair random scheduling works.
-
Check "Is today the day?"
Open the app and check today's status. The answer was decided ahead of time, so the button only reveals it. Checking again, or a hundred times, shows the same answer. Most days the answer will be "Not today", and that's normal.
-
Follow through as agreed
If today is a scheduled day, do what you agreed: usually a home test kit or a professional test that you bought separately. If your agreement includes it, you can choose to record that you completed it. In schedule-only mode, no results are stored at all.
-
Celebrate participation
Streaks, milestones and badges recognise showing up and following through, not a particular result. A negative screen is not proof of anything beyond that test, so we never treat it as a promise of sobriety. See goals and rewards.
Ways to use it
Solo, as a pair, or as a private group
Solo
For your own goals. A schedule you can't quietly move gives you a little structure and a record of your own follow-through. You don't have to share anything with anyone.
A pair
Two consenting adults, such as partners, a parent and an adult child, or friends, agree on the rules together. The schedule picks the days, so neither person has to be the one who "chose" them.
A private group
A small invite-only group can share a schedule or each keep their own, and join opt-in challenges. Members appear by nickname and share only what they approve. More on private groups.
On the day
What happens on a scheduled day
When you check and today is a scheduled day, the app tells you so. What happens next is whatever your agreement says, not something the app decides for you. A typical agreement looks like this:
- The participant uses a test kit they already have, or arranges a professional test, within the time the agreement allows.
- If the agreement includes reporting, they record that the test was completed. If it doesn't, nothing is recorded.
- Anyone else in the agreement sees only the fields the participant agreed to share.
Home test kits are screening tests. The U.S. Food and Drug Administration (FDA) describes a home result as preliminary, recommends sending a sample to a laboratory to confirm a positive home result, and notes that no test of this type is 100% accurate. Before anyone takes serious action over a result, it should be confirmed with an appropriate laboratory test, and a healthcare professional can help with interpretation. Our kit buying guide explains what a kit can and can't tell you.
A photo or self-report recorded in the app is not a laboratory-verified result, and the app does not check results.
Clear boundaries
What P in the Cup is not
Not a clinical or treatment program
P in the Cup is a scheduling and accountability tool. It doesn't diagnose, treat or monitor anyone medically, and it isn't a substitute for professional care.
Not court, employer or probation monitoring
No court, employer, treatment provider or recovery fellowship has approved it. It isn't designed to meet any official testing requirement. If you have one, follow the process you were given.
Not a testing company
We don't sell, supply, collect or process tests. Kits and lab testing are bought separately from whoever you choose.
Not something to impose on someone
It works between consenting adults who choose to take part. Every participant can see the rules, decide what to share, and leave.
The cost, in one line
The random scheduling and accountability service is free. Test kits and any laboratory testing are purchased separately.
