We are thrilled to announce the first public demo of our newest product.

The demo is free to join and you will be able to experience all the features first. There’s no registration required and the process is anonymous.

Why you should be interested

Pero allows you to save PIN codes and access them quickly and privately via Smart Stack or Accessory Rectangular complication.

✅ You own an Apple Watch
✅ You need a quick way to access your frequently used PIN codes
✅ You run iOS 17 paired with watchOS 10

If these are green for you, you should try Pero. When we worked on Pero, our goal was quality of life improvements. We achiving these with fast performance and innovative utility. Because people carry their watches all day long, Pero can save chunks of time through brief interactions.


  • Organise PIN codes by tag, like Home and Work.
  • Generate new PIN codes
  • The data is only stored on your Apple Watch
  • Polished watchOS 10 look and feel

Business Model

  • The app will cost something
  • All the features, and possibly more, will be available for those who buy the app
  • All the current features of the Apple Watch will be available as long as possible without an ongoing subscription
  • We might add more features to the iOS Companion app, and we will likely offer a subscription for using these more elaborate features


We also made a video to demonstrate the usage.
