Revyl

your iOS simulator now hot reloads from the cloud. live device updates in 3 seconds. no mac. no xcode. no local sim.

Serious question for other mobile devs: Why waste compute running Xcode sims locally, when you can just stream them from the cloud?

devtools, but for your ios app. every test run comes with cpu graphs, memory, fps, and a full network waterfall. uber demo, fully profiled.

We turned your regression suite into a living map of your app. Atlas captures every screen and action your tests touch, then assembles them into an interactive graph. Screens as nodes, actions as flows. Watch your app evolve, build over build.

having trouble using simulators across multiple worktrees and verifying your changes? built a tool that - starts an ios/android device in the cloud - hotreloads changes so you can view updates in real time Using it to run parallel worktrees and verify that the changes are correct. Don't let verification or compute be the bottleneck

The bottleneck for iOS dev is truly the CPU now. It's hard to work on features in parallel and testing if the app is compiled locally.

same flow, 10 parallel runs, fresh cloud device each time. vision-based, no selectors. if one fails, it's a real bug, not a flake. check every PR across security, design and engineering

mobile dev is no longer blocked on writing code. It is blocked on proving the change actually works across different devices claude code runs iPhone, iPad, and android in parallel, observes the app, patches the code, reruns the flows, and gives you proof that your changes work.

The Runna app has a 36 screen onboarding This is very intentional to create some value via personalization, and invoking the sunk cost fallacy before getting hit with the paywall. Designers and product engineers spend countless hours perfecting this - but they don't actually know what the app looks like for the end user.

the new mobile dev loop: type a prompt on your phone codex edits the expo app revyl dev pushes to a live phone change appears on screen didn't even touch my laptop.

You no longer need your computer to build mobile apps. Iterating on an app from my roof, Codex driving Revyl CLI, hot reloading a cloud simulator that I can use too. All from my phone.
