The Idea

Bringing a nostalgic experience to modern technology.

The goal was to bring back the charm of 90s virtual pets and reimagine the experience for Apple Watch.

The challenge: create an engaging, interactive character that feels alive, while keeping interactions simple, intuitive, and perfectly suited to a tiny screen.

The Solution

Gremlet transforms the Apple Watch into a home for a playful pixel-art gremlin.

Users can feed their pet Bolt Stew, play mini-games, clean up oil spills, and guide its behavior. The way they care for it shapes its development: into a friendly Tinker or a mischievous Grizzle.

The pet continues to evolve even when the app is closed, while a watch-face complication provides quick updates on its status.

How We Built It

We developed Gremlet as a native Apple Watch application using SwiftUI, with custom pixel-art graphics inspired by classic LCD displays.

The interface was designed specifically for the small screen, combining simple controls, expressive animations, and quick interactions.

Time-based pet progression, Digital Crown support, and WidgetKit complications extend the experience beyond the main app.

The Result

A distinctive wearable application that combines nostalgic gaming with modern Apple Watch capabilities.

Gremlet demonstrates how creative product design, custom development, and thoughtful user experience can transform a simple idea into an engaging digital product.
