Chat by day

Each day has its own conversation with Cal; open a past day to see or continue it, and learn what Cal remembers between days.

Your chat with Cal is grouped by day. The Chat tab always shows today's conversation, and a new one starts at midnight your local time.

Open a past day

In the Chat tab, tap the calendar button at the bottom to open Chat History. Change day with the arrows or by swiping left and right, or tap the date to pick from a calendar. Tap Back to today to return.
From the Diary, choose a past date and tap the + button. Depending on your version of the app, this opens that day's chat straight away or shows a list where you choose Chat about this day.

You can keep chatting on a past day. Anything you ask Cal to log there is logged on that day.

In every conversation Cal knows:

your name, targets and today's totals
your habits and your nutritional preferences
your latest weight
your coach, if you have one
things you added in the app since Cal last replied, such as a new habit, a weigh-in, a check-in you completed or a challenge you joined

Cal also reads the recent messages in the conversation you are in.

Cal can look up anything you have logged on any day. Ask "What did I have for lunch last Tuesday?" and Cal checks your logs.

Cal does not reread other days' conversations. If you told Cal something yesterday that matters, save it somewhere Cal keeps:

Food preferences, allergies and foods you avoid go in Account → Nutritional Preferences. Tell Cal and it saves them there.
Meals you eat often can be saved as favourites or regulars.
Ongoing goals can become habits.

In a very long conversation, Cal reads only the most recent messages.

Account → Clear Chat History deletes all your conversations with Cal. Your logs, habits, plans and preferences are not affected.
