Quick start

Basic timing

1. Install FlyPPTTimer or extract the portable ZIP.
2. Run FlyPPTTimer.exe.
3. Right-click the timer or tray icon and open Settings.
4. Set the default duration, timer mode, alerts, colors, and display position.
5. Use F3 to start or pause and F4 to stop and reset.

Use a presentation rule

1. Open Settings → Duration Settings.
2. Add a PowerPoint or WPS presentation.
3. Set its duration and timer mode, then enable the rule.
4. Open or start the presentation from the Remote Control window, or start it normally in PowerPoint/WPS.

Control from a phone

1. Open Remote Control from the tray menu.
2. Keep the phone and computer on the same Wi-Fi, Ethernet LAN, or phone/computer hotspot.
3. Scan the QR code.
4. Use the browser page to control timing and presentations.

Windows may ask for network access the first time remote control is enabled. Allow private-network access only when remote control is needed.

Use the large-screen timer

2. Open Settings → Appearance & Display → Large-screen timer mode.
3. Enable the large-screen timer and choose an extended display.

F5	Show or hide the regular timer

Additional hotkeys can be viewed and changed in Settings.

Privacy and network safety

• No cloud account is required.
• Presentation contents are not uploaded by FlyPPTTimer.
• Settings, rules, selected sounds, and logs remain on the local computer.
• Remote control is intended for a trusted local network and requires an access token.
• Do not forward the remote-control port to the public Internet.
• Do not publish an active QR code, full remote URL, or token.
• Check file paths and other local information before sharing logs or screenshots.
