Free Online Time & Date Tools

Most online "free" tools are loaded with ads, pop-ups, and sign-up walls. QdoShare's tools are different: open a page, use the tool, get your answer, move on. Every tool runs entirely in your browser, loads in under a second, and never asks for your email.

We're rolling these out one at a time, carefully. The full collection covers four categories of everyday time and date needs.

  • Timers & Countdowns — Online countdown timer, stopwatch, Pomodoro timer, alarm clock
  • Time & Time Zones — World clock, time zone converter, meeting planner, duration calculator
  • Date Calculators — Days between dates, date math, age calculator, day-of-week finder
  • Developer Utilities — Unix timestamp converter, ISO 8601 formatter

Meeting Presentation Countdown Timer

A Windows desktop timer built specifically for meetings, pitches, and presentations. It floats above your slides, stays transparent so it never obscures content, and gives everyone in the room a shared sense of how much time remains.

No installation, no account, no subscription. Just open the executable, type a duration, and start. The entire setup takes under 10 seconds — and the timer quietly does its job for the rest of the meeting.

  • Always-on-top — stays visible above PowerPoint, Zoom, Teams, and browser tabs
  • Transparent & compact — never blocks your slides or demo screen
  • Large readable digits — visible from across the conference room
  • Hover controls — pause, resume, reset; auto-hide after 5 seconds
  • Fullscreen "TIME'S UP" — a clear, dignified end signal, not a jarring alarm
  • Zero setup — single .exe file, runs on any Windows PC

AI Models Timeline

The AI landscape moves fast — a new flagship model lands every few weeks, and a "major update" can rewrite leaderboards overnight. Tracking the important moments across OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and dozens of other labs is genuinely hard.

The QdoShare AI Models Timeline curates the first-release date and major update milestones for the top 50 most influential AI models in one place, so you can see the whole field at a glance, compare progress between labs, and spot patterns without tab-juggling.

  • Top 50 models covered — frontier labs, open-source leaders, and Asian challengers
  • First-release date & major updates — every meaningful version with a short note on what changed
  • Filter & search — by lab, category, or release year; sort any column
  • One-click refresh — re-sorts and re-renders to the latest known state
  • Statistics date stamped — always see when the data was last compiled
  • Need more? — contact us and we'll add the model you care about

Small Windows Utilities That Just Work

Most people don't need a complicated system tool — they just need a quick answer: What Windows am I running? Is it activated? What are the full specs? The QdoShare PC Utility series answers those questions with tiny, portable tools that open Windows' own built-in dialogs for you — no commands to remember, no installers.

The series now ships two portable tools. The first release, QdoShare WinVerChecker, opens the classic Windows version dialog (winver) with one click for your OS edition, version, and licensing info — or the full System Information tool (msinfo32) for a detailed OS and hardware snapshot. The second release, QdoShare WinUpgradeChecker, goes one step further: it reads the exact Windows build you're running and reports which releases you can move to under Microsoft's release and support policies — including the upgrade type and whether your files and apps are preserved. No commands, no installers, no guesswork.

  • QdoShare WinVerChecker — first release: one click to your Windows version dialog or full system information
  • QdoShare WinUpgradeChecker — second release: see the exact Windows releases your PC can upgrade to before you touch anything
  • Two upgrade dimensions — release (e.g. Windows 10 22H2 → Windows 11 24H2) and edition (e.g. Home → Pro), reported separately
  • Portable & clean — single-file executables, no installation, no background processes
  • Roadmap — downgrade-path guidance based on Windows release and support policies

The QdoShare Philosophy

Every tool we build follows the same three principles. They're simple, but most software doesn't follow them — and that's exactly why QdoShare exists.

🎯

Focused, Not Feature-Packed

Each tool does one thing well. No settings panels full of options you'll never touch. No "pro" features behind paywalls. Just the core function, executed cleanly.

⚡

Fast From the First Click

Tools should load instantly and start working the moment you arrive. No splash screens, no onboarding wizards, no "create an account to continue." Open, use, done.

🤝

Respectful of Attention

No ads popping up mid-task. No newsletters begging for your email. No dark patterns. We build tools that quietly help — and then get out of your way.

Pick the Tool That Fits Your Day
