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 โ€” over weeks and months โ€” into a clear picture of where your money actually goes. No bank logins, no ads, no sign-up. Just you and your records. โ–  ANY CURRENCY, LOCKED IN Dollars, euros, yen, won โ€” 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. โ–  TRIPS & PROJECTS, EACH IN ITS OWN CURRENCY Group a vacation, a move, or any big plan into its own project with its own budget โ€” 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. โ–  BUDGETS THAT FIT YOU Set one overall monthly budget, per-category limits, or both. As you log, see exactly how much is left โ€” calm, simple progress, never a scolding. โ–  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. โ–  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. โ–  GENTLE REMINDERS Optional notifications nudge you to jot down today's spending and keep the habit going โ€” never noisy, never negative. โ–  STAYS ON YOUR PHONE No accounts. No sign-up. No bank logins. No cloud. Your financial data never leaves your device โ€” and there's no server for it to leave to. Back up or export your data anytime, on your terms. โ–  FOUR LANGUAGES English, Korean, Spanish, and French โ€” across the whole app. โ–  MORE โ€ข Cash counts too โ€” the spending bank-sync apps quietly miss. โ€ข Custom categories and accounts (cards, bank, cash). โ€ข Completely free โ€” no ads, no in-app purchases, no premium tier. โ–  MADE FOR Expats, students, remote workers, travelers โ€” 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.
