What it does
Every payment on its day
Each day shows how many payments fall on it, with up to three dots in the colours of their categories. A transfer, such as a card bill, carries its own mark and stays out of the count.
Twelve months either way
The calendar steps a month at a time, twelve months back and twelve ahead, with the arrows or a sideways swipe. Today returns to the current month, and past days are dimmed.
The day in detail
A tap on a day lists its payments and transfers with their amounts. From today on, each has Mark paid, and a day with everything paid shows a check mark. Open in all commitments opens the full list, narrowed to that day.
Why it exists
Payments are easier to plan around on the days they fall. A month grid shows the busy days and the empty ones together, drawn from the same records as the list and the dashboard.
Questions
Does the calendar show money in?+
No. It shows payments and transfers. Money in, such as salary received, is shown on the dashboard, under the month's total expenses.
Does longbook add payments to Apple Calendar or Google Calendar?+
No. The calendar is drawn inside longbook from your records, and nothing is written to another calendar app.
Does longbook remind me before a payment?+
Yes. The next payment stays in view on the iPhone Home Screen widget and in the Mac menu bar.
