Tools

Tools that I use daily.

A toolbox for time conversions, notes, quick support checks, network triage, and security review.

Daily tools

The tools I’d reach for most often during a normal workday: time conversion, focus, quick decisions, notes, and daily prioritization.

World timezone converter

Convert a time between time zones. This runs locally using your browser’s built-in Intl time zone data (no third-party requests).

Pick a time and zones. Result appears here.

Pomodoro timer

A simple focus timer with quick presets (10–60 minutes). Runs locally in your browser.

25:00
Choose a length and press Start.
🔥 Streak: 0 🏆 Best: 0

Reminder timer

Run up to five named timers at once. Each active timer gets its own color on the same wheel.

Scratchpad

A dead-simple notepad that autosaves to your browser (local-only). Great for jotting an IP, ticket number, or notes mid-call.

Autosaves locally as you type.

Activity logger

Keep a running workday log in your browser. Add what you did as the day goes on, then copy or export the full log when you need it.

Starts empty. Entries save in this browser until you clear them.
Date Time Activity
No activities logged yet.

Eisenhower matrix

A 2×2 prioritization board (urgent vs. important). Add tasks into a quadrant and check them off. Saved locally in your browser.

Today's priorities

1) Do

Urgent + important

    2) Schedule

    Not urgent + important

      3) Delegate

      Urgent + not important

        4) Delete

        Not urgent + not important
          Add your first task — it will stay here (local-only) until you clear it.

          General support helpers

          Quick checks for support and troubleshooting. Smaller lookups are first, and larger references sit lower in the section.

          What's my IP?

          Fetches your public IP as seen by the internet. This makes a single request to api.ipify.org.

          Click “Get my public IP”.

          MAC lookup (vendor / OUI)

          Enter a MAC address to look up the manufacturer (OUI). This sends the MAC you enter to api.macvendors.com.

          Enter a MAC address above (any common format is fine).

          Subnet helper

          Type an IPv4 CIDR (for example 10.0.5.0/24) to see the network, broadcast, mask, and usable host range.

          Enter a CIDR above to calculate details.

          Internet speed test (quick)

          A fast, lightweight download test using Cloudflare's public speed endpoint (speed.cloudflare.com). Use this for a quick read; for a full test, open Cloudflare's speed page.

          Open Cloudflare speed test
          Click “Run download test”.

          “Why is this port open?”

          Pick a common port to see what it's usually used for and how I think about securing it on a firewall or edge device.
