Tophat by Shopify

What it does

Mobile devs waste hours building branches locally just to test a PR. Tophat pulls any CI artifact and installs it on simulators or physical devices. For iOS and Android engineers.

Easily install and test mobile applications with a single click. - Shopify/tophat

Tophat is the best way to install and test any mobile application. Just add CI. With Tophat, you can skip building branches locally. Use Tophatʼs many features and APIs to easily create installation links to CI artifacts. Take your tooling a step further and offer contributors the ability to test pull requests without cloning anything! With the TophatKit SDK, you can easily extend Tophat to integrate with custom build and caching systems. This makes Tophat compatible with virtually any tooling setup you can imagine! Quick Launch allows you to add your favourite apps right to the Tophat menu. Need the latest build? Click on the icon and go! Tophat will download the latest version,…from github.com

  Hey HN, I’ve been working on Quash, a mobile-first QA tool where you can write test flows in plain English and have an agent execute them on real Android devices. We’ve finally shipped a downloadable desktop app (macOS, Intel + Apple Silicon), and you can try it now. No managed “demo” environment – it runs tests against your own apps and devices. (Can connect any device locally as well)

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
