What is it?
Mika is an Android app that takes a natural-language request and carries it out on the phone. It runs apps on a separate background screen, so the user can keep using the phone while it works. The agent reads the screen, finds buttons and inputs, taps, types and scrolls, and it can also read apps whose interfaces lack accessible labels by using built-in text recognition.
Beyond apps, Mika includes a built-in browser that opens pages in desktop mode and performs real clicks and keyboard input, and a Linux sandbox for running Python, Node and shell commands on files you send. It supports scheduled and conditional tasks, a floating capsule for progress and approvals, and a memory feature that stores facts and preferences on the device. Users can choose an ask mode, which confirms spending steps, or an autonomous mode.
Mika has no server of its own. Requests go only to the model provider the user configures, using their own API key. Presets cover many providers, plus custom OpenAI-compatible, Anthropic, Gemini and OpenAI Responses endpoints. The project is in public beta and requires Android 13 or later for task execution.
