Getting started

What is BlockClock?

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.

How do I open the app for the first time?

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.

Do I need an account?

No. BlockClock works without any account, sign-up, or login.

BlockClock Cloud

What is BlockClock Cloud?

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.

Cloud data isn't loading

If you see an error or stale data:

  1. Check your internet connection.
  2. Tap the refresh icon in the top-right of the dashboard.
  3. Open Settings and confirm Data Source is set to BlockClock Cloud.
  4. Force-quit and reopen the app.

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.

Connecting your own node

What node software is supported?

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.

How do I find my node's address and credentials?

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.

I see "Connection failed" or "Connection timed out"

Common causes, in order of likelihood:

I see "Authentication failed" / HTTP 401

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.

Can I use BlockClock with Tor or Tailscale?

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.

Can I use HTTPS / a self-signed cert?

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.

Widgets & complications

How do I add a widget?

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.

What widgets are available?

My widgets are showing wrong or stale data

This is usually one of two things:

  1. The system hasn't refreshed them recently. Open the app — BlockClock forces a refresh whenever you launch it. After about a minute, the home-screen widgets should be up to date.
  2. The OS killed the background refresh. Some launchers (especially Samsung's One UI with "Sleeping Apps") aggressively suspend background tasks. Go to your phone's Settings → Apps → BlockClock → Battery and set it to "Unrestricted." On Samsung also check Device Care → Battery → Apps that won't be put to sleep and add BlockClock.

All my widgets look the same / show the wrong widget type

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.

How often do widgets update?

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.

Apple Watch

How do I install the Watch app?

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.

How do I add a Watch complication?

Long-press your watch face → tap Edit → swipe to the complications screen → tap a slot → scroll to BlockClock → choose a complication type.

The Watch isn't showing live data

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:

Price & charts

What currencies are supported?

USD, EUR, GBP, CAD, AUD, JPY, and CHF. Change in Settings → Currency.

How do I see the price chart?

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.

The price hasn't updated in a while

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.

News tab

Where do the news articles come from?

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.

News is empty / not loading

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.

How fresh is the news feed?

Our aggregator refreshes from each publisher every 15 minutes. Items show "X min ago" relative to publication time.

Learn tab

What's in the Learn tab?

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.

Settings & data sources

How do I switch between BlockClock Cloud and my own node?

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.

How do I change the refresh interval?

Settings → Refresh interval. Options are 1, 2, 5, 10, 15, 30, and 60 minutes. Shorter intervals use more battery and bandwidth.

How do I reset to defaults?

On iOS: delete and reinstall the app (no account to lose). On Android: Settings → Apps → BlockClock → Storage → Clear Data, or delete and reinstall.

Privacy & data

What data do you collect?

None that identifies you. We don't have accounts, analytics, advertising IDs, or tracking. See our full privacy policy.

Where does my node's data go?

In Own Node mode, your node's data travels only between your phone and your node. It does not pass through our servers.

Is my node's password safe?

Your RPC credentials are stored only on your device, in the iOS/Android keychain or its equivalent. They're never transmitted to us.

Donations & tip jar

Is BlockClock free?

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.

How does the tip jar work?

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.

Will there be a paid subscription?

Not at launch. If we ever introduce paid features, the existing free functionality will stay free.

Device & OS compatibility

Installing & updates

Where do I download BlockClock?

iOS: the App Store. Android: Google Play.

How do I update?

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.

How do I know what version I'm running?

Open Settings → About inside the app.

Uninstalling & data removal

How do I uninstall BlockClock?

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.

What happens to my data when I 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.

Still stuck?

Send us an email and we'll get back to you.
