The feed
The feed is a plain list of every transaction, newest first, grouped by day. This is where you find a transaction, check it and fix it.
A row holds everything you need: the account in small type on top, then where the money went (a category, a source, or the second account for a transfer), then the tag in grey if you set one. The amount is on the right: expenses red with a minus, income green with a plus, transfers black and unsigned — they neither added nor took away.
Each day ends with two totals. “Change” is how much more or less money you had that day, and “on hand” is how much is left; currencies are counted separately and never added together.
There are two ways in: Menu → History, or the list icon in the home screen header — right next to the pencil, on its left.
And if you tap a circle on the home screen (a short tap, not a drag) the same feed opens with only that circle's transactions, its name in the header. That is the quickest way to see what the figure under the circle is made of.
Editing and deleting happen here too: a tap opens the transaction, a swipe left reveals the bin. See “Amount, date, tag” for the details.
