SigmaTracker shows all your crypto in one place: public wallet addresses on Bitcoin, Ethereum, Solana, Arbitrum One, Base, Monad, BNB Smart Chain, Polygon PoS, OP Mainnet, Avalanche C-Chain, Tron and TON, plus your Bybit and MEXC exchange balances — no account needed, and no private key ever involved.
WATCH ANY ADDRESS
Paste a public address and SigmaTracker reads its balance straight from the blockchain. One EVM address is tracked on Ethereum, Arbitrum One, Base, Monad, BNB Smart Chain, Polygon PoS, OP Mainnet and Avalanche C-Chain at once, and USDT and USDC are picked up next to the native coin on every network that has them. Get a notification when a balance changes.
CONNECT AN EXCHANGE, READ-ONLY
Connect Bybit or MEXC (spot and futures) with a read-only API key. The key and secret are stored in your iPhone's Keychain, never reach our servers, and are used only to sign requests sent from your device directly to the exchange. They stay on your iPhone unless you turn on Sync exchange keys via iCloud Keychain, which shares them only with your own devices. SigmaTracker cannot trade, withdraw or move anything. A Bybit key that isn't read-only is refused; MEXC offers no way to check a key, so the app shows you exactly which permissions to leave off.
ONE PORTFOLIO
- Total value in USD or BTC, with its 24h, 7-day or 30-day change
- A sortable assets table: quantity, price and all-time profit/loss
- Average cost from your exchange trade history where the exchange provides enough of it — and left blank where it doesn't, instead of a wrong number
- A coin without a price is marked as unknown and left out of the total, never guessed
- Small balances fold into a single dust line
MANUAL ACCOUNTS, FAVORITES, PRICE ALERTS
Type in buys and sells for holdings the app can't read on its own. Follow any coin's price and 24h change in Favorites. Set price alerts above or below the price of any coin and get notified when one is crossed.
NOT A WALLET
No private keys, no seed phrases, no signing — there is nothing in the app that can move funds. No analytics, no ads, no tracking.
SIGMATRACKER PLUS
The free version tracks up to 10 wallet addresses and one exchange account. SigmaTracker Plus, an optional auto-renewing subscription (monthly or annual), removes both limits. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel it in your App Store account settings.
