Most of a person's life happens in the days between therapy appointments — and most of it is forgotten by the time the next session starts. Between-session check-ins are a simple way to keep that experience from slipping away.
A between-session check-in is a short note a client captures in the moment — a sentence typed on their phone, or a quick voice memo — about how they are feeling or something that just happened. Instead of trying to reconstruct two weeks of ups and downs from memory at the start of a session, the client and their therapist can look at what actually occurred, when it occurred.
Therapy typically happens for an hour every week or two. That leaves roughly 167 hours where the real work of living — the arguments, the anxious mornings, the small wins — takes place with no one taking notes. By the next appointment, memory has flattened it all into a vague "it was okay, I think." The sharp, useful details are gone.
This is a well-known limitation of recall: we remember how something ended, or how intense it was, far better than what led up to it. Check-ins work with that reality instead of against it. They catch the moment while it is still specific.
The best check-ins are small enough that a person will actually do them. A few examples:
None of these take more than a moment. The point is not to journal at length — it is to leave a breadcrumb.
Therapy "homework" — a thought record, an exposure task, a worksheet — is valuable, but it asks the client to remember to do a structured thing later. A check-in asks for far less: a few seconds, right now, when something is happening. Many people who never finish homework will happily fire off a one-line note. The two approaches complement each other rather than compete.
Because check-ins touch sensitive, health-related experience, privacy and consent are not optional extras — they are the foundation.
Between is built around exactly this: clients send a quick note in the moment, it's summarized into the pattern, and — with consent — their therapist sees it before the next session. Private and consent-first by design.

Homework is usually a structured task to complete before the next session. A check-in is lighter and in-the-moment: a few seconds to jot a note when something happens. They complement each other.
No. They're a support between appointments, not a substitute for professional care, and not a crisis service. In an emergency, contact 988 or your local emergency number.
With a consent-first tool they are: notes belong to the client and are only shared with a therapist, or analyzed by AI, when the client explicitly opts in.
