TTK -> Time To Kill🗡️

A Windows desktop app that runs countdown timers against processes. When a timer expires, it takes an action -- kill the process, suspend it, demote its priority, or other options. Useful for automatically ending game sessions, closing distracting apps after a set period, or any situation where you want a process to stop on a schedule.

Built with .NET 10 and Avalonia UI. Runs in the system tray.

Features

Timer actions -- each timer targets a process by name and runs one of these actions when time is up:

• Kill -- terminates the process via taskkill
• Force Kill -- same, but with /F flag
• Suspend -- freezes all threads in the process (it stays in memory but stops executing)
• Demote Priority -- sets the process to below-normal priority
• Launch & Kill -- launches a process when the timer starts, then force-kills it when time expires. Good for "let this run for exactly N minutes" scenarios.

Other features:

• Pause, resume, and cancel running timers
• Auto-start on launch -- mark timers to begin counting down automatically when the app opens
• Custom display labels -- name your timers something readable instead of showing raw process names
• Process name flexibility -- enter just a name like discord.exe or a full path like C:\Apps\discord.exe
• Automatic grouping -- multiple timers targeting the same process are grouped under a collapsible header
• Reorder timers with up/down controls
• Duration presets (30s, 5m, 15m, 30m, 1h, 2h) for quick setup
• System tray icon with status indicator (idle/active/fired) and tooltip showing active timer countdowns
• Minimizes to tray on close -- the app keeps running in the background
• Themes -- six built-in color themes (dark, light, zenburn, monokai, solarized dark, solarized light) selectable from the gear icon

Usage

1. Click + Add Timer to create a new timer preset.
2. Enter a process name (e.g. notepad.exe), set a duration, and pick an action.
3. Click the play button on a timer row to start the countdown.
4. When the timer reaches zero, the action executes. A notification bar at the bottom confirms what happened.

Timers persist across app restarts. Closing the window hides the app to the system tray -- right-click the tray icon or click it to reopen. Use the tray menu "Exit" to actually quit.

Building

Requires the .NET 10 SDK.

From Visual Studio or Rider: Open TimeToKill.sln and build normally.

From command line:

dotnet build

Standalone executable:

Run build_standalone.bat to produce a single-file framework-dependent exe in the publish/ directory:

build_standalone.bat

This creates a single .exe that requires the .NET 10 runtime to be installed on the target machine. It is not self-contained.

Configuration

Timer presets are stored as JSON at:

~/.config/timetokill/presets.json
aka
%USERPROFILE%\.config\timetokill\presets.json

You can back this file up or edit it by hand if needed. The format is straightforward -- an array of timer preset objects with fields like processName, duration, actionType, autoRunOnStart, and sortOrder.

TODO

• Better Icon
• GLOB/Relocatable paths
• Timer nudge (add/subtract time on the fly)
• More actions (hibernate, custom command, etc)
• Figure out a better joke about TTL, 'time to waste' -> 'ttk'
