You build tonight's Shield.
Three taps on your phone: Ana, Kavya, Brady. Everyone out together sees live location tonight and gets a note when each person makes it home. Your trusted contacts are already set. They always are.

ShieldSip is a smartwatch app built for one specific danger: drink spiking. It does not test what is in your glass. It watches what spiking does to your body. It learns your normal, notices the crash, and asks if you are okay. Thirty seconds without your passcode and your location, an alarm, and a recording are already on their way to the people you trust.

SCROLL
A normal night.
ShieldSip already knows what your body looks like when everything is fine. Your resting rate, your variability, the way you move. It compares you only to you.
Dancing is not danger.
Heart rate climbs to 124 and for half a second it looks alarming. But movement is high at the same time, and that combination is a person dancing, not a person in trouble. ShieldSip never reacts to one number.
Expected activity pattern
Your vitals stop looking like you.
Heart rate falling well below your baseline. Variability collapsing. Movement unsteady, then still. Not dancing, not walking, not exercise. Flagged.
It asks you first.
A tap on your wrist and 30 seconds to enter your passcode. A passcode, not a button, because a button can be pressed by anyone. Answer, and nothing is sent.
No answer. It acts.
Location to your trusted contacts. Alarm on. Audio recording started, with a time stamped vitals log saved beside it. Evidence you did not have to be conscious to collect.
Help is already moving.
Everyone you trusted knows where you are. Nothing about tonight depended on you noticing in time. That is the entire point.

When it matters
30
seconds
Most of the night moves in hours. The part that decides everything moves in seconds. ShieldSip is built around noticing the change while those seconds are still available.
GHB?
Ketamine?
Benzodiazepines?
Rohypnol?
ShieldSip does not identify the drug.
It identifies when something may be wrong.
It reads the physiological and behavioral changes a smartwatch can actually measure, and looks for combinations worth checking on you about. That distinction is deliberate, and it is why ShieldSip stays honest about what it can and cannot know.
The problem
Spiking is common, and almost none of it is ever proven.
Victims commonly report memory loss, and in many reported cases sexual assault occurred during the same incident. It almost never results in consequences for the person responsible, because victims wake up with no memory and no proof.
respondents across 22 countries reported experiencing drink spiking at some point in their lives.
of victims lost memory during the incident. No memory means no evidence. No evidence means no report.
of spiking incidents are never reported to police. Half of those who stayed silent said they did not see the point.
of people who reported being spiked also reported a sexual assault during the same incident. Most had no memory of it afterward.
Sources: Davies et al., Global Drug Survey, 22 countries (2024); Drinkaware and Anglia Ruskin University (2024).
Every safety tool you already have waits for you to ask.
A panic button, a check in text, a test strip. All of them assume you will realize something is wrong and still be able to act on it. Spiking removes exactly that ability.

Test yourself
No single signal makes the decision.
The hard part of building ShieldSip is not noticing a strange number. It is knowing which combinations mean someone is in trouble and which ones mean someone is dancing. See how you do.
Would you alert?
You are ShieldSip.
These are the only three things you can see. Decide.

Build your Shield
Who has you tonight?
Type the friends you are going out with, and watch the map and the promise update. Your Shield is rebuilt every night, in seconds.
If tonight goes wrong
Maya, Jules and Riya will know where you are within 30 seconds.
Your trusted contacts are notified no matter what. Your Shield gets escalation alerts only if you turn that on.
Being honest
What ShieldSip cannot know.
A changed heart rate cannot identify a drug.
A missed check in does not confirm an emergency.
Alcohol, exercise, anxiety, medication, and illness can all create similar patterns.
A smartwatch alert is not a medical diagnosis and is not a substitute for emergency services.
Responsible safety technology should communicate uncertainty, not hide it.
Where we are
Built in the open, one phase at a time.
01Done
Research
Understanding what spiking does to the body, which signals a smartwatch can actually read, and where every existing safety tool fails.
02In progress
Prototype
Continuous heart rate, variability, and motion monitoring running natively on smartwatch and phone, with detection rules tuned against real baselines.
03Next
Beta
A first cohort wearing ShieldSip on real nights out, so the false positive rate is measured in the environment it has to survive.
04Planned
Expansion
Campus licensing for universities and student organizations, more supported devices, and detection profiles beyond a single night out.
