Pennylog: Expense Tracker

The more you log, the more your money makes sense.

Pennylog is a daily expense tracker for people whose lives span more than
one currency. Log what you spend in a few seconds, in any currency, and
watch it build — over weeks and months — into a clear picture of where your
money actually goes. No bank logins, no ads, no sign-up. Just you and your
records.

■ ANY CURRENCY, LOCKED IN
Dollars, euros, yen, won — log spending in any currency. Each entry is saved
at that day's exchange rate, so your past totals stay accurate even when
rates move later. Add a secondary currency to see every amount in your home
currency at a glance.

■ TRIPS & PROJECTS, EACH IN ITS OWN CURRENCY
Group a vacation, a move, or any big plan into its own project with its own
budget — and give each one its own currency. A Tokyo trip in yen, a Paris
trip in euros, each locked at the day's rate. Project spending stays separate
from your everyday totals, so a trip to Tokyo never makes your normal month
look off.

■ BUDGETS THAT FIT YOU
Set one overall monthly budget, per-category limits, or both. As you log, see
exactly how much is left — calm, simple progress, never a scolding.

■ STATISTICS THAT GET RICHER
A category donut, monthly trends, and a per-category detail you can scroll
back through month by month. View your days as a list or on a calendar.
Long-press a category to mute it for a moment and see the rest. The longer you
keep it, the more it shows.

■ WEEKLY & MONTHLY RECAP
See this week against last: your biggest expense, daily average, no-spend
days, and which categories went up or down. Gentle awareness, not guilt.

■ GENTLE REMINDERS
Optional notifications nudge you to jot down today's spending and keep the
habit going — never noisy, never negative.

■ STAYS ON YOUR PHONE
No accounts. No sign-up. No bank logins. No cloud. Your financial data never
leaves your device — and there's no server for it to leave to. Back up or
export your data anytime, on your terms.

■ FOUR LANGUAGES
English, Korean, Spanish, and French — across the whole app.

■ MORE
• Cash counts too — the spending bank-sync apps quietly miss.
• Custom categories and accounts (cards, bank, cash).
• Completely free — no ads, no in-app purchases, no premium tier.

■ MADE FOR
Expats, students, remote workers, travelers — anyone living or moving between
currencies who wants one simple, private place to record daily spending.

A line a day is all it takes. The longer you keep it, the better it gets.
