I m an expat, so I spend money in several currencies while thinking about my finances in one base currency.
Many expense trackers can convert currencies, but the conversion date changes the meaning of your history. If an app recalculates an old purchase using today s exchange rate, the value of that purchase changes whenever you reopen the report.
I designed Tanda to convert each expense into the user s chosen profile currency using the rate from the expense date. Tanda keeps that historical rate with the expense, so an old spending report does not change because the currency market moved.
This looked like a small implementation detail at first. For anyone living across currencies, it determines whether the spending history can be trusted.
Hi Product Hunt, I'm Omar, the maker of Tanda.
I built Tanda because I'm too lazy to fill in forms and manage my finances. Logging a coffee meant four taps: amount, category, date, save. I stopped using expense trackers.
I wanted to say “sixty pounds, groceries” and put my phone away. It was the ability I kept wishing Siri had. Tanda turns that sentence into a categorized expense, ready to confirm.
I built the features around how I manage money:
Multi-currency for expats. Tanda converts each expense into the base currency you choose and keeps the exchange rate from the expense date. I live across currencies, so this mattered most to me.
Cash and multiple accounts. I use both, and Tanda lets me track them in one place without linking my bank accounts.
A simple spending screen. I can open Tanda and see where my money went without interpreting a complicated chart.
Shared Vaults. My partner and I can log expenses into one shared space and see the same running total.
An AI assistant. I can ask, “How much did I spend on food this month?” and get a direct answer.
You choose how much information leaves your phone:
Standard: Third-party services process the audio and financial information. This provides the fastest and most accurate result.
On-Device: Audio stays on your phone. Tanda sends the transcript to a third-party service to turn it into an expense, intent, or AI query.
Full Privacy: Audio and financial information stay on your device. Speech recognition and expense processing run on-device, including in airplane mode.
Tanda has a free plan with no card required. Pro is optional.
I’d value feedback on whether the voice flow feels fast enough and whether the multi-currency history matches how you think about spending. I’ll be here throughout launch day.
Product Hunt offer: use code 1TANDAMONTH for one month of Tanda Pro free. The code expires January 1, 2027.
The offline sync thing is actually pretty clutch, tried logging expenses on a plane with no wifi and it just worked. Multi-currency support is a nice touch too, way less friction than my old setup.
@altmelis74860 I’m glad you gave Tanda the plane test so soon. It stores each expense on your phone while you’re offline and syncs it when you land. I built it for dead zones, whether you’re on a plane or miles from a signal.
Multi-currency is pure selfishness. I’m an expat, and I got tired of converting expenses each time I paid in another currency. Curious what you ran before this.
