Useful details
Short answers about CoinCalc's purpose, data and availability.
Is CoinCalc an exchange or wallet?
No. It does not execute trades, hold assets or connect to exchange accounts. It is an informational calculator and converter.
Where do quotes come from?
From Binance's public market-data API. Quotes can be delayed or unavailable and may differ from executable trading prices.
Do I need an account?
No CoinCalc account is required. Apple processes Pro purchases, and optional private sync works through iCloud on your Apple ID.
Which devices are supported?
iPhone and iPad running iOS or iPadOS 16 or later. An internet connection is required for current quotes.
When will the App Store link be available?
Version 1.0 is being prepared for publication. A direct link will appear here after the App Store listing is created and approved.
Every number in its place.
