What NightWatch shows
It is built from the same presence record as Online History. NightWatch is a lens on it, not a different signal.
- The last time the contact was online before the night began, night by night.
- The first time they came online in the morning.
- Every online session during the night, with times and durations.
- Ten nights side by side, so a normal night and an unusual one are easy to tell apart.
Bedtime and wake-up patterns, without asking
Most people's phones go quiet at roughly the same time each night and wake up at roughly the same time each morning. NightWatch turns those two moments into a simple timeline per night. When the routine holds, you see it. When one night runs until 3am, you see that too.
This is what people mean when they ask whether someone was online at night on WhatsApp: not a single last-seen stamp, but the shape of the whole night.
What NightWatch is not
It does not show who they were talking to, and it does not read anything. Online at 2am means the app was open at 2am; ChatWatch does not know why. Treat it as a pattern to notice, not as proof of anything.
It also cannot see through privacy settings. If a contact hides their online status from you in WhatsApp, their nights are hidden from ChatWatch as well.

Common questions about NightWatch
How many nights does NightWatch show?
- The last 10 nights for each tracked contact, each with the last connection before bed, the first in the morning, and any sessions in between.
Can NightWatch tell me who they were chatting with at night?
- No. It shows when the contact was online, not with whom. Chat Probability can compare two contacts' activity, but that is a pattern, not a message log.
Is NightWatch in the free preview?
- No. The free preview includes Online History for one contact. NightWatch and Chat Probability unlock with the 3-day free trial and the paid plan.
