One sum, every currency
Pennyglot looks and works like the iPhone’s own Calculator, with one difference: as you type, each calculation also appears in up to four other currencies.
Free for iPhone · iOS 26 or later · English and Türkçe · Nothing collected
Pick up to five currencies
Tap the dashed tile to add one, and search by name or code, in English or Turkish. Hold a tile to reorder or remove.
History keeps each conversion
Every calculation you finish with = is saved with its conversions, at the rates of that moment. Copy it, or use it again.
Just a calculator, when you want
Switch to Basic mode from the grid button, and Pennyglot is a plain calculator.
The screens show sample rates.
Where the rates come from
From ExchangeRate-API, which publishes new rates about once a day. About Pennyglot shows when they were published, and the calculator warns once they’re a week old. Offline, the app uses the last rates it downloaded, for up to 30 days after they were published.
Nothing collected
No accounts, ads, analytics or tracking. Your currencies and History stay on your device and its own backups. The Privacy Policy says exactly what the app sends.
