LilMoon
Version 2.0 on the Mac App Store

The Bitcoin price and the fee, without opening anything

Checking the price means a tab you did not mean to open. Checking the fee means a block explorer and a number in sat/vB.

LilMoon keeps both on your desktop and in your menu bar. You just look.

A day with LilMoon

Four glances, and not one tab

Loading the Bitcoin price

Nothing opened, nothing to close

  1. 08:10

    The glance

    The price in your currency, the 24 hour change beside it, and a line drawn from where the day opened, so the two never disagree. You look at your own screen and you are done.

  2. 11:40

    The fee, in money

    Sat per vByte is a unit almost nobody thinks in. Two and sixty are the same transaction, thirty times apart. LilMoon shows the fastest rate in sat/vB and in your own money, coloured cheap or dear.

  3. 15:05

    The alert

    Waiting for the mempool to calm down means checking more often, not less. So LilMoon watches instead, and tells you when the fee drops below the number you picked.

  4. 19:30

    The menu bar

    The price, the fees, or just the icon, up in the menu bar. Switch the desktop window off entirely if that is all you want.

Appearance

Anything that sits on your desktop all day has to look like it belongs there

A widget you notice is a widget you switch off within a week. So there are twelve looks to start from, and every colour, typeface, size and corner can be yours after that. Two of them draw no panel at all.

Effects

Eight of the sixteen, drawn by your browser. The app adds sheen, emboss, bloom, iridescence, halftone, CRT curve, lens fringing and the glitch.

The glance

Looking is free. Checking is not.

Opening a tab to see one number puts you in a tab. Ten minutes later you have read three things you did not go there for.

LilMoon is already on the desktop. Nothing opened, nothing to close.

Underneath, if you want them: the latest block and how long ago it landed, the mempool backlog, the next difficulty retarget and the next halving. Every row is a switch.

Alerts

Be told, instead of watching

Waiting for a level means checking, which is the thing you were trying to stop doing.

Set rules on the price, the 24 hour change, the fastest fee or the economy fee, above or below a number you pick. Each carries its own cooldown, so a market sitting on your number does not nag you all afternoon.

Tell me if it moves five per cent either way stays true as the price drifts. A price threshold has to be retyped every few months.

In practice

The parts you only notice when they are missing

The menu bar popover

The sparkline, the block, the fees, the retarget and the halving in one place, with the overlay toggles beside them.

No server, no account

Nothing is routed through a server of ours, because there is not one. No sign-up, no analytics, no ads. LilMoon has no idea who you are, and asks for nothing but a network connection.

Where you put it

On the desktop below your windows, or above them if you prefer. Drag it anywhere and it stays put between launches. Turn on open at login and it starts when your Mac does.

New in 2.0

What changed in this release

Which one

LilMoon or Moonitor?

LilMoon

A glance

Bitcoin only, no portfolio, one question: what is happening right now. A widget you leave on your desktop and mostly ignore.

A portfolio tracker

Sixteen exchanges, what you hold and what you paid, and your profit and loss. An app you open when you want to know how you are doing.

Both are made by the same person, both keep your data on your own machine, and neither asks for an exchange API key.

Questions

Frequently asked

Is LilMoon a subscription?

No. LilMoon is $2.99 once on the Mac App Store. There is no subscription, no upgrade tier and nothing to unlock later.

What does LilMoon need to run?

A Mac on macOS 15 or later. The build is universal, so it runs natively on both Apple silicon and Intel.

Do I need an account?

No. There is no sign-up, no login and no analytics. LilMoon stores your preferences on your Mac and asks for nothing but a network connection.

Where do the numbers come from?

Prices from Binance.com, Binance.us, Kraken or Coinbase, whichever you pick. Blocks and fees from mempool.space. Nothing is routed through a server of ours, because there isn't one.

Does the widget sit on top of my windows?

Only if you want it to. By default it sits on the desktop below your windows. Turn on keep above other windows and it floats over everything, and you can drag it anywhere you like. It stays put between launches.

Do alerts work when LilMoon is closed?

No. LilMoon checks every 30 seconds while it is running, so alerts stop when you quit or restart your Mac. Turn on open at login and it starts when your Mac does.

Does LilMoon track my portfolio?

No. LilMoon follows Bitcoin only and holds no holdings, no transactions and no balances. Moonitor is the portfolio tracker; LilMoon is the glance.
