What we build

We focus on practical, well-crafted mobile apps: our own products and selected projects, released on the Apple App Store and Google Play.

iPhone & iPad apps

Native-feeling iOS apps that follow Apple's design guidelines and run smoothly on current devices.

Android apps

Apps for phones and tablets on Google Play, built to work well across the wide range of Android devices.

Utilities & tools

Focused apps that do one job well, from trackers and calculators to everyday productivity tools.

Support & updates

We keep our apps current with new OS releases, fix issues promptly and respond to user feedback.

How we work

Every app goes through the same straightforward process, from first idea to the App Store.

Shape the idea

Define who the app is for, the problem it solves and the smallest version worth shipping.

Design

Sketch screens and flows, then refine them until the app feels obvious to use.

Build & test

Develop in short cycles and test on real devices before anything reaches users.

Launch & improve

Release on the App Store and Google Play, then keep improving based on real use.

About Hammerstone Labs

A hammerstone was one of humanity's first tools: a simple, dependable stone used to shape every other tool that came after it. That idea guides how we work. We believe the best apps are like good tools: easy to pick up, reliable every time and made with care.

Hammerstone Labs LLC is a small, independent software company based in Connecticut. We build and publish our own mobile apps and stand behind every one of them.
