Activities with a numerical response allow you to send your client written messages that your clients will respond to with a number. These types of activities are great to use when you want your client to keep track of something such as hours of exercise or number of triggers they've experienced.
When you assign your client an activity with a numerical response, your client will receive a notification on their mobile device. Once they've opened the Therachat client app, your client will see the activity in their activity feed. Your client will then be able to open the activity, read its description, and reply with a number. After they've completed the activity, you'll be notified and be able to see their response on your Therachat dashboard.
