BlockClock

A native app is on the way Coming soon

BlockClock for iPhone and Android is being built. There is no date to give you and none is going to be invented for this page — it ships when it is good enough to leave running on a shelf. In the meantime the web app already does most of the job, and it does it today.

What a native app adds

A web page can already fill the screen, hold the display awake and install to a home screen. These four are the things it genuinely cannot do, and they are the reason the app is worth building at all.

  • Planned

    A home-screen widget

    Block height and price sitting on the home screen next to everything else, without opening anything. A web page cannot draw outside its own window; a native app can.

  • Planned

    Alerts while you are away

    A notification when a block milestone lands, when the price crosses a level you set, or when mempool fees finally drop. This needs code that runs while the app is closed, which is the one thing a browser tab is designed never to do.

  • Planned

    Proper always-on display

    Phones with an always-on screen expose it only to native apps. The web app has to keep the display fully lit instead, which works but costs more battery than it should.

  • Planned

    History that lives on the device

    Charts kept locally rather than refetched, so the app opens with something on screen immediately and survives a patchy connection.

How it is being built

In Flutter, one codebase for both iPhone and Android. That choice was made at the start of this project, not retrofitted: the Flutter shell has been sitting in the BlockClock repository since day one, waiting for the web side to be worth extending.

Two things have to happen before it reaches a store, and neither is a coding problem: an Apple developer account, which costs money every year, and Google Play's one-off registration. Those come when the app is ready, not before.

Nothing here is promised. Every feature above is planned, not delivered. This page exists so you know where the product is going — not so it can claim ground it has not taken yet. When something ships, it will appear on this page as something you can download, not as a bullet point.

What to use today

The web app. Added to a home screen it opens on its own icon, fills the screen with no browser bar, and keeps the display awake — which covers the reason most people want a clock app in the first place. It costs nothing and there is no store involved.

Lightning QR code for tipping BlockClock

Buy me a coffee — in sats

BlockClock is free, has no account, no tracking, and no paywall on any number it shows. Tips are what pay for the developer accounts the app needs, and they are the honest way to say the work is worth continuing.

  • 1,000 sats · a nod
  • 5,000 sats · a coffee
  • 21,000 sats · the good kind
