lazylog

What you spent, next to what happened.

Most expense apps tell you where the money went. A journal tells you what was going on. lazylog keeps both against the same day — because the useful question is rarely “how much on groceries in August”, it’s “what was I doing the week I spent like that”.

No account. No cloud. No network connection at all.

Shipped the rewrite finally — the whole thing runs offline now, which was the point. Walked back along the canal instead of taking the tram.

What it does

Day view

The home screen. Spending and the day’s journal entry, together.

Month calendar

Each day tinted by what it cost, with a dot on the days you wrote something. Tap to open it.

Stats

Where the money went by category, and a six-month trend of spending against income.

Accounts

Cash, cards, bank accounts, each with a running balance.

Export

Spending as CSV, journal as CSV, or the lot as JSON. Your data leaves when you decide.

Nothing else

No ads, no upsell, no “premium”. It is a personal tool, not a funnel.

What it deliberately does not do

This is the list that keeps the app usable, not a roadmap. If you want these, you want Money Manager — it does them well, and it is a heavier app for it.

Privacy

Not a policy. A property of the build:

The honest flip side: there is no backup. Lose the phone, lose the data. Export a JSON backup now and then — that is the trade you are making in exchange for nobody else holding your spending and your diary.
