Gbbrsh is a small design and development studio. We make our own apps, like Hbts and Keystreaks, and build for others too.
Work
iPhone app, 2026
A habit tracker where every habit is a journey.
Every day each habit gets a ticket to use. Tickets wear out when they sit unused, routines run like timed journeys, and progress lives in a passport full of stamps.
Coming soon to the App Store
Web app, 2025
Typing practice built for focus.
A minimal, ad-free place to type and get faster, with live metrics, combinable typing modes and leaderboards. Keystreaks for Education brings it to schools.

How we work
Everything we make, our own apps first, follows a few rules.
No ads, no tracking. What you make stays yours, on your device whenever it can.
Fast to load, quick to answer, and nothing you didn’t ask for.
Small and minimal by default, so the parts that matter can be big, beautiful and a little noisy.
Design and code come from the same hands, so nothing gets lost between the sketch and what ships.
Services
Native iPhone apps in Swift and SwiftUI, from the first prototype to the App Store.
Custom websites and web apps that don’t look like every other template.
Interface and experience reviews, design systems, and the architecture behind an app that runs like a well-oiled machine.
New identities and refreshes, big or small: logo, type, color and the rules that hold them together.
Studio
Gbbrsh makes and holds Hbts and Keystreaks, and the products that come next will live here too.
The studio is led by Ivan Viveros, a designer and developer known online as Zteetch.
When a project needs more hands, we bring in trusted collaborators for just that project.
Based in Mexico. We work in English and Spanish.
Gbbrsh is gibberish, minus the vowels. The name comes from Keystreaks, the first product we built: its gibberish mode shuffles the letters of every word, so you stop typing from muscle memory and actually learn the keys. It’s harder, and more rewarding.
Every mode in Keystreaks has an icon. For gibberish, a quick scribble on an iPad felt right straight away. That scribble is now our logo.
