PreGuru: Timer & Slide Remote
Talk timer on your Apple Watch
$7.99
Finish on time: extra-large remaining time with colour and haptic warnings. Flick your wrist on Apple Watch to advance slides. Record every talk. Receiver: preguru.app
Finish right on time. Advance slides with a flick of the wrist.
A timer and remote for talks, lectures and presentations. Your remaining time fills the screen of your Apple Watch and iPhone in extra-large digits. As it runs low the colour shifts white → orange → red; overtime flashes red and the end is a buzz on your wrist. And one flick of the wrist moves to the next slide. No clicker in hand, eyes on the room. PreGuru is for speakers, executives, professors and trainers — everyone who has to deliver in front of people.
■ Own your time, own the room.
Elapsed and remaining time in extra-large digits. As time runs low the colour shifts white → orange → red, and if you run over, a flashing red frame and a vibration make sure you know. Swap elapsed and remaining with a tap. Never lose credibility by running over again.
■ Run the whole session.
An independent countdown timer for exercises, breaks or workshops — separate from your presentation time. 3 / 5 / 10-minute presets, or set the minutes with the crown. It ends with a buzz and a sound.
■ Show the time to the room.
With the free receiver installed, the remaining and elapsed time can be shown large on the Mac / PC screen — over the presentation, or in its own window for the chair.
■ One flick. No glance. — Air Swipe
Swing the wrist wearing your Apple Watch and the slide advances. No clicker to hold, no lectern to look down at. Your eyes stay on the room while you keep talking. Large on-screen buttons and Apple Watch Double Tap work too.
■ Your wrist tells you when it will land.
Apple Watch dims and eventually sleeps once it decides you are not looking, and flicks made then never arrive. PreGuru does not hide that — it reports it through your wrist. Two rising taps: you can send. One falling buzz: it may sleep soon, so tap the face once. One light tap: the slide was sent. You never have to look at the watch.
■ It learns how you move.
Motion sensing is combined with on-device machine learning to suppress unintended triggers. Undo an accidental advance within 2.5 seconds and PreGuru records it as a mistake, growing more attuned to your own gesture the more you present. All learning and processing stay on the device — nothing ever leaves it.
* This misfire-prevention technology is U.S. patent pending.
■ Drive the app you already use.
Install the free PreGuru Receiver on your Mac or PC (get it at https://preguru.app — no account, nothing more to buy) and control Keynote, PowerPoint, Google Slides, PDF, Canva, Prezi and anything else that advances with the arrow keys.
■ Capture what matters.
Long-form recording on your iPhone, continuing in the background so you can review it later. External microphones are supported. Hand the audio to a generative AI and transcription takes moments.
■ iPhone alone works too.
Time management, recording and slide control all work with just your iPhone — no Apple Watch required.
■ One-time purchase.
No subscription. Buy once, use every feature.
■ And your hands are free.
No clicker to hold, no laptop to hover over. With both hands free, you gesture, you move, you connect — because a presentation is a live performance. Command the stage like the speakers you admire. PreGuru gives you that freedom.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Cleaner Apple Watch controls and fixes for Wi-Fi connection trouble.
Apple Watch
- A single tap on the time display no longer does anything, so a light tap to wake
the screen cannot change the display or a setting. Switching between elapsed and
remaining is now a double tap, and the air-swipe ON/OFF chip at the top is a triple tap.
- With Wake Duration set to 70 seconds, the watch stays awake for 70 seconds after you
touch the screen, and any small movement wakes it instantly. A light single tap on
the face during a talk starts another 70 seconds.
- The slide buttons are shorter, so an unseen touch is less likely to hit them.
- The ON indicator is larger and pulses faster.
iPhone
- While connected to a receiver, a gear button on the status row now lets you switch
to a different Mac/PC (for venues with more than one receiver).
- If an old address was left in the IP address field under connection settings,
automatic discovery stopped working entirely. The IP address field is now the first
thing tried; if it does not respond within a few seconds, automatic discovery runs
alongside it, and the settings screen explains why and offers to return to it.
- iPhone and Mac can now connect directly even without a shared Wi-Fi network
(requires the updated Mac receiver).
- Wording such as "Mac IP address" now reads "Mac/PC" throughout.
