BlockClock is a free Bitcoin network dashboard for iPhone, Apple Watch, Android, and home-screen widgets. It shows live block height, fee estimates, mempool depth, BTC price (with 24h/7d/30d/1y charts), halving countdown, supply progress, and a curated news feed. You can use it with BlockClock Cloud (zero setup, free) or by plugging in your own Bitcoin Core / Knots node.
On first launch, BlockClock asks whether you want to use BlockClock Cloud or connect your own node. You can change this choice any time in Settings → Data Source.
No. BlockClock works without any account, sign-up, or login.
A free read-only Bitcoin data service we operate. It pulls live data from public Bitcoin sources and serves it to the app so you can use BlockClock without running your own node. No account required.
If you see an error or stale data:
If the issue persists for more than a few minutes, our service may be experiencing a brief interruption — try again in 5–10 minutes, or contact us.
Any Bitcoin node that exposes a standard JSON-RPC interface — Bitcoin Core,
Bitcoin Knots, and most Core-derived implementations. The app uses
getblockchaininfo, getmempoolinfo, estimatesmartfee, and
similar standard RPC calls.
Your node's RPC settings live in its bitcoin.conf file. The relevant lines are:
rpcuser=<your-username> rpcpassword=<your-password> rpcallowip=192.168.0.0/16 # or wherever your phone connects from rpcbind=0.0.0.0 server=1
The default RPC port is 8332 for mainnet, 18332 for testnet. Use your
node's LAN IP (e.g. 192.168.1.117) — not 127.0.0.1, which only works
on the node itself.
Common causes, in order of likelihood:
rpcallowip doesn't include your phone's subnet. Most home
networks use 192.168.x.x or 10.0.x.x.rpcbind is missing or set to 127.0.0.1. Set it to
0.0.0.0 (or your node's LAN IP) so it accepts external connections.The RPC username or password in Settings doesn't match what's in your node's
bitcoin.conf. If you've recently rotated credentials, update both sides. Whitespace
in fields is a common cause.
Yes. BlockClock connects to whatever host/port you give it, so any VPN, mesh network, or tunneling
solution that exposes your node's RPC port to your phone works. Tailscale's Magic DNS hostnames
(e.g. node.tailnet-name.ts.net) are supported.
Plain HTTP to your node over your private network is supported. HTTPS with a publicly-trusted certificate is supported. Self-signed certificates are not currently supported.
iOS: long-press on the home screen → tap the + in the top-left → search "BlockClock" → choose your widget size and tap Add Widget.
Android: long-press an empty area of the home screen → Widgets → scroll to "BlockClock" → drag the widget you want to your home screen.
This is usually one of two things:
Some launchers cache widget views and occasionally render a stale view. Workaround: long-press the misbehaving widget, Remove it, then add it again from the widget picker. If the problem recurs, contact us with your device model and OS version — we're actively investigating launcher-specific cases.
BlockClock asks the OS to refresh widgets every 15 minutes (the system minimum on both iOS and Android). The OS schedules the actual updates based on battery, network, and recent usage. Opening the app forces an immediate refresh.
The Watch app installs automatically when you install BlockClock on a paired iPhone. If it doesn't appear, open the Watch app on iPhone → scroll to BlockClock under "Available Apps" → tap Install.
Long-press your watch face → tap Edit → swipe to the complications screen → tap a slot → scroll to BlockClock → choose a complication type.
The Watch app fetches data the same way the phone does — through BlockClock Cloud or your own node. If the phone works but the Watch doesn't:
USD, EUR, GBP, CAD, AUD, JPY, and CHF. Change in Settings → Currency.
Tap the BTC price anywhere on the dashboard. A chart opens with 24-hour, 7-day, 30-day, and 1-year ranges. On iPhone, rotate to landscape for a full-width chart.
BlockClock refreshes the price on the interval you chose in Settings (default: every 5 minutes). You can force an immediate refresh from the dashboard's refresh button. The data source is Kraken, served through our cache layer.
BlockClock aggregates the public RSS feeds of CoinDesk, Bitcoin Magazine, Bitcoin.com News, Decrypt, and The Block. Tapping any article opens it on the publisher's own website in your browser — we don't reproduce article text in the app.
Check your internet connection and pull-to-refresh the News tab. If still empty, force-quit and reopen the app. If the issue persists, contact us.
Our aggregator refreshes from each publisher every 15 minutes. Items show "X min ago" relative to publication time.
A curated list of Bitcoin podcasts, educators, and resources for newcomers and experienced users alike. Tapping any item opens the source on their website. We don't host the content — we just point at it.
Open Settings from the gear icon at the top of the dashboard, then choose your data source under Data Source. The change is immediate — no restart needed.
Settings → Refresh interval. Options are 1, 2, 5, 10, 15, 30, and 60 minutes. Shorter intervals use more battery and bandwidth.
On iOS: delete and reinstall the app (no account to lose). On Android: Settings → Apps → BlockClock → Storage → Clear Data, or delete and reinstall.
None that identifies you. We don't have accounts, analytics, advertising IDs, or tracking. See our full privacy policy.
In Own Node mode, your node's data travels only between your phone and your node. It does not pass through our servers.
Your RPC credentials are stored only on your device, in the iOS/Android keychain or its equivalent. They're never transmitted to us.
Yes. The full app — Cloud mode, own-node mode, watch app, widgets, charts, news — is free, with no paywall and no advertising. If you'd like to support development, there's an optional tip jar in Settings.
You can buy us a coffee in the app via standard App Store / Play Store in-app purchases. Payments are handled by Apple or Google. SegWhat LLC receives the proceeds (after store fees). No subscription, no recurring charges — tip once or as many times as you like.
Not at launch. If we ever introduce paid features, the existing free functionality will stay free.

We'd love to hear it. Email info@segwhat.com with your idea. We can't promise to ship everything, but we read everything.
iOS: the App Store. Android: Google Play.
Updates ship through the App Store / Play Store like any other app. Most devices auto-update; you can also manually check for updates in the store.
Open Settings → About inside the app.
iOS: long-press the app icon → Remove App → Delete App. This also removes the Watch app on the paired Apple Watch.
Android: long-press the app icon → Uninstall, or via Settings → Apps → BlockClock → Uninstall.
All locally-stored data (your node settings, currency choice, refresh interval) is deleted along with the app. We don't retain any server-side records of you in the first place, so there's nothing for us to delete.
