Does FlyClock work with PDF presentations?

Yes. FlyClock is the only presentation timer that supports PDF slideshows. It works with Foxit PDF Reader, Adobe Acrobat, Sumatra PDF, and other PDF viewers that support fullscreen mode.

Do I need to modify my PowerPoint or PDF files to use FlyClock?

No. FlyClock never modifies your files. It runs as a floating overlay and detects fullscreen playback automatically — no plugins, no embedded macros, no file changes.

Does FlyClock require an internet connection?

No. FlyClock runs completely offline. Remote control works over your local network (LAN) — no cloud, no internet required.

How much does FlyClock cost?

FlyClock is free to try with no time limit. The Professional license is a one-time purchase of $27.99 for lifetime use on one PC. An Enterprise license covers 10 devices for $159.

FlyClock — Automatic Presentation Timer for PowerPoint & PDF

Why FlyClock

Every Other Timer Needs You to Click Start.
FlyClock Doesn't.

The only presentation timer that senses your slideshow — PPT or PDF — and handles the clock so you can handle the room.

Defending your PhD. Pitching to investors. Running a conference. In these moments, your brain has no room for one more thing. Yet most presenters are still manually starting timers, watching clocks disappear behind fullscreen slides, or breaking their train of thought to glance at their phone. The tool meant to help becomes one more thing to manage.

Forgetting to click Start

Nerves take over. You're on stage. The timer never started. You find out when it's too late.

Timer buried by fullscreen

You go fullscreen. The timer disappears behind your slides. You're flying blind.

PDF? No timer exists for that

Defending your thesis or presenting a design deck in PDF? Every existing timer ignores you.

FlyClock
Built for this

Auto-Sensing Engine

Starts When You Go Fullscreen

No Start button. No shortcuts. No forgetting. FlyClock detects PPT and PDF presentation state at the system level — the moment you go fullscreen, timing begins. Exit fullscreen, timing stops. Automatically.

PDF Presentations — Finally

The Only Timer That Works for PDF

Defending your thesis in PDF? Presenting a design deck in Acrobat? FlyClock works with Foxit, Adobe Acrobat, Sumatra PDF and more — not just PowerPoint. No other timer does this.

Always Visible · Zero Traces

Never Hidden. Never Modifies Your Files.

Fullscreen-proof and non-intrusive. Low-level window rendering keeps the timer visible on any screen setup. And FlyClock never writes to your PPT or PDF — drag it anywhere, leave no trace.

Remote Control — No Internet Needed

Your Backstage Team Runs the Clock

Scan a QR code. Control from any phone or tablet on the same Wi-Fi. Pause, reset, or trigger an alert in real time — while the presenter stays 100% focused on the audience. No cloud. No data leaves your network. Works in environments where internet isn't allowed.

Presenter ⟷ LAN only · fully offline Controller
