I made WatchDog because I was tired of the little wave of panic every time I had to leave my MacBook on a cafe table to grab a coffee or run to the restroom. Here is how it works. You arm it before you step away. If someone touches or moves your Mac, it sounds a loud alarm and pings your iPhone...

As answered by people managing WatchDogApp.de and Diffyn.
WatchDogApp.de's answer
WatchDog is one of the few Mac anti-theft tools that reacts in the moment instead of after the fact. Most options only help you locate your Mac once it is already gone. WatchDog sounds a loud alarm and pings your iPhone the instant someone touches or moves your MacBook, locks the screen, and resists quick shutdown attempts, so a thief gets noticed before they can walk away.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
WatchDogApp.de's answer
Trackers like Find My and Prey are recovery tools that help you chase your Mac after it is stolen. WatchDog is a deterrent. It makes a scene the second someone reaches for your laptop, which is what actually stops a grab in a busy cafe or library. You arm it with a tap, it works offline over Bluetooth, and it never touches your files.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
WatchDogApp.de's answer
WatchDog is a native macOS app with a companion app for iPhone. It uses Bluetooth for arming, disarming, and proximity detection, and push notifications to deliver instant alerts to your iPhone.

WatchDogApp.de's answer
People who work on a MacBook in public. Students in libraries, remote workers and freelancers in cafes, and digital nomads in coworking spaces. Anyone who has to leave their laptop on a table to grab a coffee or use the restroom and wants to step away without worrying it gets taken.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
WatchDogApp.de's answer
I work out of cafes and coworking spaces, and I could never relax when I had to leave my MacBook to grab a coffee or use the restroom. Find My only helps after your Mac is already gone. I wanted something that reacts in the moment, so I built WatchDog. You arm it, step away, and if anyone touches your Mac it sets off a loud alarm and pings your phone right away.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
