Why OAH

A finance app that respects how you actually live.

Most finance apps treat you like an American with one bank, one job, and one currency. OAH was built for the rest of us — with rent income, side gigs, and crypto.

🔀

Every income and expense type, one place

Salary, side hustles, rent, gifts, fines — log any kind of income or expense without juggling apps or spreadsheets.

🏘️

Real-world assets, not just stocks

Track the apartment, the loan to your cousin, the side business — not just what Wall Street thinks counts as an investment.

🌐

Truly bilingual

English and Spanish, built in from day one. Not a half-baked translation bolted on later.

🔐

Your data stays yours

No selling to advertisers. No "anonymised insights" sold to third parties. Just your numbers, on your phone.

Available now

FAQ

Questions, answered.

Is OAH Accounting free?

Yes — the core app is free to use. We may introduce paid features later for advanced needs, but the day-to-day tracking will always be free.

Is my financial data secure?

Your data is encrypted in transit and at rest. We don't sell it, share it, or use it to train anything. You can delete your account and all associated data at any time.

What languages and currencies do you support?

The app is fully available in English and Spanish, and uses the Euro by default. Multi-currency support is on the roadmap and will roll out alongside the investment tracking feature.

Is there an iOS version?

Android launches first. iOS is on the roadmap and you can join the waitlist below to be notified.

Does it connect to my bank account?

Not yet — OAH is built for manual logging and Excel import, which means more control and no third-party access to your bank. Bank connections may come in a future version if there's enough demand.

Can I really track real estate or business investments?

Yes. For assets without a live price feed (like real estate or a private business), you set the current value manually — typically when you get a valuation. Linked maintenance expenses and rental income keep your profit/loss honest over time.

Stop guessing where your money goes.

Get OAH for Android at launch. Track your income, expenses, bills, and investments in one place — and finally see the whole picture.
