Free to start · no bank linking required
Log what you spend during the week. Sunday morning, open a short letter that tells you what happened, what changed, and whether you're on track — in plain language, not a chart you have to decode.
No card, no bank connection. Just an email and a password.
Week of Aug 10–16
Hey —
You spent $412 this week, about $38 less than last week. Groceries crept up a bit, but eating out dropped almost in half. At this pace, your "trip fund" goal lands two weeks early.
How it works
Type it in as you go, or drop in a CSV export from your bank in one go — either works, no setup required.
Open the app and your letter is ready: what happened, how it compares to last week, and one honest observation worth noticing. Turn on a reminder and your browser will nudge you.
Two minutes, not twenty. No charts to interpret. Save it as an image if you want to keep a record — or share it.

Hey —
Here's what happened with your money this week.
You spent $412 total, down $38 from last week's $450. Nice.
Hover a row for the letter's actual note on it.
Eating out dropped almost in half from last week — that's the whole reason this week came in lower. Groceries crept up $12, worth keeping an eye on but nothing to worry about.
Your Trip Fund goal is at $680 of $1,200. Keep this pace and you'll get there — $520 to go.
Talk next Sunday.

Questions
Not exactly. Most budgeting apps want you checking a dashboard constantly. Sunday Letter is closer to a weekly recap — you log what you spend, and once a week you get a short, plain-language letter about it. If you want real budgeting tools (monthly limits per category, warnings when you're close to over), those are available on the Max plan.
No. Sunday Letter never asks for your bank login or account numbers. You log expenses manually, or import a CSV file that you export yourself from your bank or card's website — the same file most budgeting apps would ask you to link an account for.
Yes — the Free plan is free forever, no card required, and includes a real weekly letter, one savings goal, and up to 20 expenses a month. Letter+ ($8/mo) and Max ($19.99/mo) raise those limits and add features like income tracking, budgeting, and net worth tracking for people who want more.
Those are built to be checked often — dashboards, category rules, real-time syncing. Sunday Letter is built to be checked once a week, in about two minutes. If you've tried a full expense tracker before and stopped using it because it felt like a chore, this is built for that specific problem.
Yes, on Letter+ and Max. You can log one-time income (like a freelance payment) or recurring income (like a paycheck), and it shows up in your weekly letter alongside spending.
Nothing bad — just log what you remember when you're back. Letter+ and Max also let you backfill expenses for past days you forgot to log at the time, so your history stays accurate even if you fall behind.
