An independent app studio · Scotland

Honest software,
forged with care.

DagdaForge builds small, sharp apps that respect your time, your money and your privacy. No ads, no tracking, no accounts you didn't ask for — just tools that do one job properly.

Trupence

The real price, before you pay.

Most currency apps quote the mid-market rate — the number you only get if your card adds no fees. Trupence shows what a foreign price will really cost on the cards you actually carry. Point your camera at a price tag, tap to capture, and see the honest total in your home currency.

  • Scan any price. Camera + on-device OCR reads price tags, menus and receipts. Nothing is uploaded.
  • Your real card fees. Add the cards you carry — Wise, Revolut, Monzo, Amex and more — and see what each would land on your statement.
  • The DCC shield. When a terminal asks "pay in your home currency?", Trupence reminds you to decline — that trap quietly costs around 5%.
  • Best-card pick. Your cards, ranked cheapest-first for the exact price in front of you.
  • Trips & spending. Budget a trip, log purchases in a tap, export everything to CSV.
  • Offline & private. Rates cached for roaming-off travel. No account, no analytics, no ads — your data stays on your device.
Get it on Google Play

Free, with no ads and nothing hidden behind a sign-up.

Rates and card-fee figures are indicative estimates for guidance only — your bank's final charge may vary. Not financial advice.

Trupence converter screen: ¥2,400 compared across your cards — Monzo cheapest at £11.18, Wise £11.23, Amex £11.52, with the full charge breakdown.
Actual app — live ECB rates, real card fees.

In the forge

Trupence is the first piece off the anvil. Here's what's glowing in the coals — no dates promised, only work in progress.

Planned

Trupence for iOS

The same honest converter, scanner and DCC shield, on iPhone. Built on the same cross-platform core as the Android app.

Exploring

Trupence Pro

Deeper trip insights and power-user extras for frequent travellers — while the core app stays free, with no ads and no tracking.

Still glowing

About the studio

DagdaForge is a one-person studio based in Scotland, named for the Dagda — the great craftsman of Irish myth, keeper of a cauldron that never ran empty. We like the idea: build things generously, and build them well.

Every DagdaForge app follows the same few rules. They're not a manifesto, just how we'd want software made for us.

  • Private by default. Your data lives on your device. We don't run servers that hold it, because we don't collect it.
  • No ads, no tracking. Not now, not "anonymised", not ever.
  • Honest numbers. If a figure is an estimate, it's labelled as one.
  • Small and sharp. One job per app, done properly, working offline where it matters.
