Why it exists

Three prices. One glance.

Crypto Analyzer began as one person’s tool for exactly this: what you paid, where the price is now and how far it sits above its one-year low, side by side on each holding card. The context is on screen before you decide anything.

01 / Inside the app

The detail behind the balance.

Explore holdings, costs and UK capital-gains records in one place.

01

Portfolio

Your holdings, in perspective.

See what you hold, its cost basis and its reference value. Bring supported exchange exports together without connecting an exchange account.

  • A view across your portfolios Review individual portfolios or bring them together in a combined view.
  • Know what makes up the balance Inspect each asset and its share of your imported holdings.
  • Put value beside cost Review the difference with the source records and their limits in view.
Where it stops

The view is derived from the rows you import. Missing periods, external wallets or unsupported activity change what it can describe.

02

Costs & fees

Understand what it cost.

See the charges in your imported records, then examine the estimates alongside them. Follow the breakdown from the total to each asset.

  • Start with the recorded charges Trading fees and withdrawal costs stay visible as recorded amounts.
  • See where estimates enter Spread estimates carry their own label, separate from imported fees.
  • Follow the breakdown Review costs by asset and type, with assumptions available to inspect.
Where it stops

Only costs your import actually contains can be totalled. Anything charged on a venue or in a format you have not imported is missing from this figure, not zero.

03

Tax records

Follow the calculation.

Trace UK disposal records through their matching rules. Review the tax-year summary and export supporting detail for yourself or your adviser.

  • Inspect the matching trail Review same-day, 30-day and Section 104 records behind the figures.
  • Bring the tax year together Read SA108-aligned supporting summaries alongside disposal detail.
  • Take the context with you Export methodology and data-quality checks with the Filing Pack.
Where it stops

Matching runs over the rows you imported, for the periods those rows cover. Disposals recorded anywhere else are not in this trail.

DEDICATED MAC EDITION · IN POLISHING

And on the Mac? Not yet.

A separate, dedicated Mac edition is being polished. It is not publicly downloadable yet, and there is no release date. For now, Crypto Analyzer is made for iPhone and iPad.

What a Mac release would require
Before any public direct release

The app must be Developer ID-signed and notarized, with a published version and checksum for macOS 12 or later. Crypto Analyzer will never ask you to bypass Gatekeeper or suppress a macOS security warning.

For iPhone and iPad, use an App Store link only while this website marks the release available. When the dedicated Mac app launches, download it only from cryptoanalyzer.app and verify the published version and checksum. Crypto Analyzer never asks for a seed phrase, private key, exchange password or permission to move assets.

Good questions. Clear answers.

Does Crypto Analyzer connect to my exchange?

No. The current App Store release supports Coinbase retail, Coinbase Advanced Trade, Coinbase Pro, Crypto.com App Token Wallet, Binance Spot transaction history and Kraken Ledgers. You choose the file from Files; Crypto Analyzer does not ask for an exchange login or trading access. Treat changed or unlisted formats as unsupported until this website and the App Store mark them available.

What data leaves my device?

The privacy policy describes imported transaction history, portfolio balances and calculations as app-local.

  • Public market-data and FX providers may receive limited request and connection data, such as symbols, dates, quote currencies, an IP address, and device or usage metadata, under their own policies. If you configure a provider-specific market-data API key, it is sent only to that provider for those requests.
  • Apple’s current App Store privacy label says Other Financial Info, User ID, Device ID and Other Usage Data may be collected and linked to you for app functionality or analytics. The label is developer-provided and Apple says it has not verified the information.
Does it submit my taxes to HMRC?
No. The current release organises UK capital-gains records using same-day, 30-day and Section 104 matching, and can export supporting detail for review. It does not submit a return, determine your obligations or replace professional advice.
Can I explore it without my own data?
Yes. Choose “Try Demo First” in the app to load a clearly labelled sample portfolio and explore the product before importing anything.
Which Apple devices are supported?
The current app is made for iPhone and iPad and requires iOS 18.1 or later or iPadOS 18.1 or later; the App Store edition is not verified for macOS. The dedicated macOS 12+ edition is separate, being polished and not publicly downloadable yet.

Never send an unredacted transaction export, wallet address, seed phrase, private key, password or API key.
