Pennylog: Expense Tracker
Track spending in any currency
Free · Designed for iPad. Not verified for macOS.
Splitting a receipt? Open the calculator right in the amount field. Any currency, locked to that day's rate. No bank logins, no account, no ads. Free.
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.
