One app, four platforms. Paste any public wallet address and watch it — holdings, value, history, alarms. No account needed to look.
The beta installs directly (outside Google Play), so Android asks you to approve it once.
The beta is not yet code-signed, so Windows shows a one-time SmartScreen notice. It is signed at v1 through the Microsoft Store.
The .dmg is signed with an Apple Developer ID and notarized by Apple, so it opens without a security warning.
Every release publishes a SHA-256 checksum on this page. If you want to confirm the file you got is the file we published, run this in Terminal and compare it to the value above:
shasum -a 256 ~/Downloads/KOINIkeyview-0.1.10.dmg
You never have to do this. It's here because the people who care about not exposing their keys tend to be the same people who like checking.
A private key. A seed phrase. A wallet connection. A payment method. KŌINIkeyview reads public blockchain data and nothing else — there is no signing capability in the app at all. If anything claiming to be KŌINIkeyview asks you for a key or a recovery phrase, it isn't us.
0.1.10 — Display currency fixed across every platform: pick euro (or any of 40 currencies) and every figure converts. Rates are now remembered on your device, and if a fresh rate ever can\u2019t be fetched the app tells you why instead of quietly showing dollars.
0.1.9 — Your watchlist now shows one combined total across every wallet you watch, and you can see every value in your own currency: Settings › Currency offers 40, including euros and pounds. Holdings stay priced in US dollars and are converted for display.
0.1.6 — Every holding now shows its token logo, with the EthFan family (ETH Fan Token Ecosystem, ETHFan Burn, ETH Fan Burn Peace) served directly by KŌINIkeyview so their marks and prices are always right. The card under your net worth now rotates through the KŌINI family of apps, each with its own logo, and opens the one you tap.
0.1.4 — Mac, Windows, iPhone & Android beta · October 2026. Tokens that only trade on decentralised exchanges are now priced and shown in your portfolio instead of being left out, and the watchlist button works again after the app has been left open for a long time.
0.1.3 — Mac, Windows, iPhone & Android beta · September 2026. First Windows build (direct download, unsigned beta) and the iPhone beta is now open to anyone via TestFlight. The app icon is now the KŌINIkeyview keyhole mark on every platform. No functional changes.
0.1.2 — macOS beta · September 2026. Price accuracy layer. Every price is now cross-checked against independent sources and real pool liquidity before it is shown; anything that can't be verified is listed separately as “not reliably priced” and kept out of your total instead of inflating it. Portfolio shows when prices were last confirmed.
0.1.1 — macOS beta · July 2026. Alarm notifications now land as native Mac banners while the app is open — the same alarms that push to your phone. Allow notifications on first launch.
0.1.0 — macOS beta · July 2026. First desktop build. The full view loop — address lookup, portfolio, allocation, and cross-chain history across seven EVM chains plus Solana — plus free accounts, watchlist sync, and the alarm engine shared with the Android beta. Signed with an Apple Developer ID and notarized by Apple.
