How to Assign Winnow as CBT Homework: A Practical Guide for Clinicians

Quick answer

Assign Winnow by doing one real entry together in session, agreeing on a specific trigger to log, and deciding in advance how the client will bring entries back (on their phone or as a PDF/CSV export). The app supplies the structure; you supply the target and the review. Most homework fails at the handoff, not the format, so most of this guide is about the handoff.

Why the handoff matters more than the app

If you have read our broader look at CBT homework apps clinicians can actually assign, you know the general criteria: low friction, structure that matches your modality, and something you can review. This post assumes you have decided to use Winnow and want a repeatable way to introduce it.

The pattern we see in clinician write-ups and practice conversations is consistent: an assignment that is explained in the last two minutes of a session ("try this app this week") tends to produce one entry, or none. An assignment that is practiced in the room, tied to a specific moment, and reviewed at the start of the next session tends to stick. The app is the same in both cases. The difference is how you set it up.

What Winnow gives you to work with

It helps to know exactly what the app does, so you can describe it accurately to clients:

• A seven-step thought record. Situation, emotions, automatic thought, cognitive distortions, evidence for and against, a balanced thought, and a re-rating of the emotions. This mirrors the worksheet most CBT clinicians already teach.
• Quick mood check-ins. A short log with an emotion list and intensity ratings, useful for clients who are not ready for a full record.
• Fifteen named cognitive distortions, each with a plain-language explanation, so the client is not guessing at vocabulary you introduced once in session.
• Trends. Mood and distortion patterns over time, which give you something concrete to point to.
• A crisis safety plan with warning signs, coping strategies, contacts, and quick access to 988.
• PDF and CSV export, so the client can share entries with you on their terms.
• Privacy by design. Entries stay on the device, and no account is required.

Winnow also has an optional paid tier with extra insight features and unlimited exports. You do not need it to run the workflow below, but if you want weekly exports, tell clients the free tier limits how many they can make each month.

A five-step introduction workflow

Here is the sequence, using a plausible composite case: a client working on health anxiety who spirals after reading symptom information online. This is an illustration of a workflow, not a real client.

1. Pick one target before you mention the app

Decide on a single, observable trigger. "Any time you catch yourself searching symptoms" is better than "notice your anxious thoughts." A narrow target gives the client a clear yes/no on whether an entry was warranted, and gives you a clean pattern to review.

2. Install and complete one entry together

With the client, install Winnow (it is free to start and needs no sign-up) and walk through one entry from earlier that week. Have the client type it, not you. Ten minutes here saves the confusion of an unfamiliar format at home, where a stressed client is least likely to work out the steps alone.

Point out the distortion list at this stage. In our example, the client might tag "catastrophizing" on the thought "this headache means something is seriously wrong." Seeing the label attached to their own thought is usually more useful than any definition you give.

3. Set the trigger and the time window

Say it out loud and write it in your note: "When you notice the symptom-search urge, open Winnow and complete an entry within the hour. Aim for two or three this week." Specific beats aspirational. Two or three is a realistic number, and it leaves room to talk about what got in the way if the client logs none.

Also do the safety-plan step here if it is clinically appropriate. Completing the safety plan in session, rather than leaving it as an untouched screen, means the app's most important feature is populated before anyone needs it.

4. Agree on how entries come back

This is the step most clinicians skip. Decide with the client, before they leave:

• Show me on your phone at the start of session. Simplest, no data leaves the device, and works for most clients.
• Export a PDF or CSV and send it before session. Better for clinicians who want to prepare, but it creates a document that lands in your email or files, so it needs to be handled like any other client document.
• Bring three entries, your choice. A useful middle path that lets the client select what they are comfortable with.

Say plainly that you review entries in session and not in real time, and that anything urgent goes through your usual crisis process rather than through the app. That expectation protects both of you.

5. Review the pattern, not just completion

At the next session, spend the first ten minutes on the entries. "Did you do it?" is the least useful question. Better ones: What was the trigger each time? Which distortion tags kept repeating? How far did the emotion rating move between the first and last step? If the re-rating barely changes, the balanced thought may be too generic, which is a coaching opportunity rather than a compliance problem.

Then adjust for the next week: a new target, a harder trigger, or a step back to simple mood check-ins if full records felt like too much.

Handling the common snags

The client did nothing. Ask what the moment looked like when they meant to log. Often the answer is "I was in bed and did not want to open anything," which tells you the trigger and time window need to change, not the client's motivation.

The entries are all identical. That is usually a sign the thought is a core belief rather than a situational automatic thought. It is a good candidate for deeper work in session, and the repeated entries are your evidence.

The client is worried about privacy. Winnow keeps entries on the device and does not require an account, which answers many concerns. Two things do leave the device, and clients should know both. Exports, which the client controls. And, if they use the optional Pro AI features (distortion suggestions, balanced-thought suggestions, pattern analysis), the text of that thought-record step is sent through a PsyFi proxy to OpenAI for processing, without name, email, or device ID, and is not stored by the proxy. A client who wants nothing off-device can simply not use those features; the core thought record works without them. Details are in the Winnow privacy policy.

Clients who do not want an app. Keep paper. A worksheet done consistently beats an app that is never opened.

Where this fits in your documentation workflow

Homework review is part of the session, so it should show up in your note. If you draft notes with PsyFi Notes, you can capture what you reviewed (targets, patterns, adjustments) as part of the session record rather than reconstructing it later, and you always review and finalize the draft yourself. PsyFi's tools are HIPAA-aligned with a BAA available, but the client's own device and Winnow are outside that boundary, which is why the export decision in step four matters.

For prompts that work well alongside thought records, see our guide to CBT journaling prompts for therapists, and if you want your clients to understand the method before they start, the Winnow thought record guide is written in plain language for exactly that.

A one-page version you can reuse

If you want to make this repeatable across your caseload, keep this checklist in your own template:

1. One target trigger, written down.
2. One real entry completed together in session.
3. A specific window ("within the hour") and a realistic number of entries.
4. A decision on how entries come back, and what stays on the client's phone.
5. Ten minutes at the start of the next session, spent on patterns.
