Your day, from photos you took
A month is just thirty little boxes. You already took the picture — Bento Days reads its timestamp and drops it into the right box, so filling the page is picking rather than typing. Add a line, a tag, what it cost, and by the end of the month the page has quietly added itself up.
Each box shows whatever you left there — the photo, a tag, an amount, or nothing at all. Most of the month stays blank, and that is the point.
Today's photos appear in a drawer — swipe through and keep the ones worth remembering. Or take one right there in the app. Then a line, a tag, a price if you feel like it; every field is optional.
How many entries, how many days you actually wrote something, and what it all came to. Set a monthly budget and the page tells you where you stand.
If some entries have no amount, it says so instead of showing a total that looks exact. It counts what you wrote down and nothing more.
