Personal finance and wealth tracking, built around a single calendar. Log a transaction in under five seconds. Watch the streak grow. See where your money actually goes.
Erisai comes from Perisai — Indonesian for shield. Saving is the first defense. The streak is the discipline. The app is the witness.
Built in Surabaya, for the Indonesian who is ready to take the first real step. The one almost no one talks about, where every other step in financial wellness stands or falls.
Most personal finance apps are built somewhere else, for someone else. Erisai is built for Indonesia, for the long haul, for people who actually want the habit to stick.

The ladder every household climbs. Erisai is built for the bottom — the rungs almost no one talks about, where every step above stands or falls.
Green for income, red for expense — on every calendar cell. Three summary pills stay pinned above. Tap any day, add from anywhere via the green center button.
Add savings, e-wallets, credit cards, investments. Pick a currency per account — Erisai pulls live exchange rates and converts everything into one net worth in your base currency.
Interest rates per account project next month's earnings. Admin fees tracked automatically.
One transaction logged is one day on the streak. The number compounds quietly. Heatmap of your last five weeks, badges for the long milestones, a Pulse score that turns months of logging into one honest read of how you're doing.
No leaderboards. No social comparison. The streak is between you and yourself; Erisai is the witness.
Erisai syncs to your Google Drive, not ours. The file lives in your account, accessible only by you and Erisai on your devices. We never see your transactions. Read the full policy →
No card. No account. Free forever for the basics. The rest takes care of itself.
