About

Mobile work means juggling simulators, emulators and a different set of tools for each. Agentsims puts every iOS simulator and Android device you have running in one browser workspace. Boot devices, flip settings like dark mode, location or network across them, read the accessibility tree, follow the logs and, in React Native and Expo apps, jump from what is on screen to the code behind it.

It also lets coding agents work on a phone the way you would. A full CLI gives them the screen and the controls, and the skill that ships with it teaches them to use both well: with it, Pi on GPT-5.6 Sol completed 113 of the 116 tasks in the AndroidWorld benchmark.

At TurboML, it is part of how the team builds and tests mobile every day.
