Three different annoyances
A utility earns its place by removing something you were doing by hand. These three target chores that are individually small and collectively expensive: the tab you keep opening, the Downloads folder you keep not sorting, and the date you keep half-remembering.
Blocking distractions
NoMore watches the frontmost app and the current browser tab, and when either matches your block list it steps in front. No countdown to wait out, no allowance to spend - the site simply does not open while it is on the list.

Two design decisions are worth knowing before you install it. First, everything is evaluated on your Mac: the URL of your current tab is compared against your list locally and is never sent anywhere. Second, it is bypassable on purpose. The job is to convert a reflex into a decision, and a blocker that traps you gets uninstalled the first time it is inconvenient at the wrong moment.
If your problem is starting work rather than drifting away from it, a timer is the better tool - see the focus apps.
Organizing files
Sweep watches your Downloads folder and files things by rules you write: screenshots here, invoices there, disk images to the bin after a month. It runs quietly in the menu bar, and it also adds a Finder extension so you can trigger a rule on a folder directly.

The important property is that every move is undoable, including bulk operations. Nothing is deleted, nothing is renamed silently, and there is a history you can walk backwards. Automation that touches your files is only worth having if reversing it is as cheap as running it.
Counting down
Await keeps the dates you actually care about in the menu bar - a launch, a flight, a birthday, a deadline - and counts down to them. When the moment arrives, it takes over the screen with a celebration rather than a notification you will swipe away without reading.

It is the smallest app in the portfolio at around 2 MB, it is pay-what-you-want, and it does exactly one thing.
What they have in common
All three are native macOS apps, sandboxed, signed and notarized, running on macOS 14 or later, in English, Turkish, German and Spanish. None of them needs an account, none of them syncs anything, and the paid ones come with a 14-day trial that needs neither a card nor an email address.
