The native Bitcoin mempool app for iPhone.
Live mempool, network fees and the whole Bitcoin network in one calm, glanceable app, plus a built-in block explorer, interactive charts back to 2011, and watch-only wallets with Face ID. Free, open source, no accounts, no subscription.
The mempool, finally native on iPhone.
mempool.space powers Bitcoin's most-loved explorer, on the web and on Android. Bitcoin Insight brings that same live data to a real, native iOS app: the mempool, network fees, a full block explorer and the entire network, designed to be the best way to follow the mempool on iPhone, built on the public mempool.space API.
Everything you need to read the network.
From the live dashboard to interactive charts, a block explorer and watch-only wallets, one calm, focused app for all of Bitcoin's network data.
Live Dashboard
Price, mempool, network fees, block height, hashrate, difficulty, Moscow time, circulating supply, the halving countdown and Lightning stats, auto-refreshing every 10 seconds, with a 24h price sparkline at a glance.
Interactive Charts
Tap a metric and scrub its history with your finger, price back to 2011 in 19 currencies, fees, hashrate, difficulty, Moscow time, Lightning growth and the emission curve, all at a fluid 60 fps.
Block Explorer
Search any transaction, block or address and watch the chain advance live, a tracking-free explorer built right in.
Watch-Only Wallets
Add any xpub, ypub, zpub or single address to track balances and full transaction history, never a private key.
Face ID Security
Lock your wallet behind Face ID, Touch ID or Optic ID and blur balances with a tap. Everything stays on your device in the iOS Keychain.
Home & Lock Widgets
14 widgets for price, fees, halving, block height and more, across Home Screen and Lock Screen sizes, the only paid extra, a one-time unlock.
Search any transaction, block or address.
One search box for the whole blockchain, paste a block height, a hash, a transaction ID or any address and Bitcoin Insight figures out the rest. Then tap from block to transaction to address and back, the way the chain actually connects.
A live "Latest Blocks" feed streams new blocks the moment they're mined, with a gentle haptic when a new tip lands. And it's strictly read-only: looking up an address never adds it to your wallet and is never saved on your device.
- Search blocks, transactions and addresses
- Live latest-blocks feed over a real-time connection
- Inputs, outputs, fees, confirmations, fully linked
- Tracking-free: no account, addresses never stored
Touch any moment in Bitcoin's history.
Most metrics have a finger-scrubbable chart. Drag across the line and the header turns into a precise value-and-date readout with a subtle haptic tick on every point. Lift your finger and it resets.
Price history reaches all the way back to 2011, in your currency, with 19 to choose from. Fees, hashrate, difficulty, mempool, Lightning growth and Moscow time all get the same treatment, and the emission and halving curves let you scrub decades into the future.
- Scrub with live value & date readout, 24H → All
- Full price history to 2011 in 19 currencies
- Fees, hashrate, difficulty, Lightning & Moscow time
- Smooth scrolling across years of data
Watch your stack. Keep your keys.
Add an xpub, ypub or zpub to follow an entire wallet, or paste a single address. Bitcoin Insight derives your addresses on-device, adds up the balances and pulls in the full transaction history, valued live in your currency across 19 options.
It stays strictly watch-only. Paste a private key or seed phrase by accident and the app blocks it, so your keys stay yours and your coins never move.
- xpub, ypub, zpub or a single Bitcoin address
- Multiple wallets with a combined total balance
- Full history of sent and received transactions
- 100% watch-only, private keys are rejected
Private by default. Locked by Face ID.
Lock the Wallet tab behind Face ID, Touch ID or Optic ID, the rest of the app stays open. Balances blur on every launch and re-hide whenever you switch away, so no one reads your net worth over your shoulder, and your wallet never even shows up in the app-switcher preview.
There are no accounts and no servers holding your data. Wallets live only in the iOS Keychain on your device, and network data comes straight from the public mempool.space API.
- Face ID / Touch ID / Optic ID wallet lock
- Tap-to-reveal, hide-on-launch balance blur
- Keychain storage, no cloud, no account
- App-switcher privacy cover
A lot of app. None of the catches.
Many Bitcoin apps ask you to choose: pay a subscription, accept ads, or settle for a website. Bitcoin Insight doesn't.
