Turn supported exchange CSVs into clear UK capital gains, cost basis, fees and portfolio performance—privately on your device. No account, subscription or ads.

Turn supported exchange CSVs into a clear view of your UK crypto tax position, portfolio performance, cost basis and fees—privately on your iPhone or iPad. Crypto Analyzer requires no account, subscription or ads, and keeps your transaction and tax records on your device.

UNDERSTAND YOUR UK TAX POSITION

• Calculate disposals using HMRC share-matching order: same-day, 30-day bed-and-breakfast, then the Section 104 pool • Review gains, losses, proceeds and Annual Exempt Amount usage by UK tax year • Preserve exact decimal values from supported CSV exports • Check filing readiness across acquisition history, fees, FX sources and methodology • Export SA108 box-aligned summaries, disposal details and a Filing Pack for professional review

SEE THE FULL STORY BEHIND YOUR BALANCE

• Track live value, cost basis, holdings and performance • Explore asset allocation, holding time and performance over time • Understand imported fees plus estimated spread, slippage and conversion costs • Compare multiple portfolios and exchanges in one combined view • Model potential disposals and monitor 30-day rebuy windows

PRIVATE BY DESIGN

• No cloud sync, advertising or tracking SDK • Your transaction history, balances, wallet addresses and tax records stay on your device unless you choose to export them • Import CSVs directly—no exchange API credentials • Protect sensitive actions with Face ID or your device passcode • Redact wallet addresses from shared exports by default
