Agentic coding on mobile: plan, act, ship

Treena launches a mobile coding agent with plan and agent modes, enabling developers to edit code, run commands, and push to GitHub from a phone. The bring-your-own-key approach lets users connect their own AI models, making mobile a first-class development surface for shipping fixes on the go.

Agentic coding on mobile: plan, act, ship How plan and agent modes change mobile development, why bring-your-own-key matters, and what a coding agent can do on a phone that a chat app cannot. Treena Chatbots can suggest code. Agents can change systems. That distinction is why mobile finally works for real software work. A chat transcript is not an IDE. An agent with tools inside a workspace is. Plan mode vs Agent mode Treena exposes two deliberate modes: Plan mode The agent drafts a step-by-step approach. You approve before anything is written. Ideal when: - You are new to the repo - The change touches auth, billing, or data - You want a mental model before execution Agent mode The agent edits, runs commands, and iterates until the task is done or blocked . Ideal when: - The task is well-scoped - You trust the surrounding tests - Speed matters more than ceremony One toggle. Same conversation. Different risk profiles. Tools beat pure text A useful mobile agent must be able to: - Read and search files - Apply patches - Run the terminal - Observe errors and try again - Produce a reviewable diff Without tools, you are copy-pasting into a chat window. With tools, the phone becomes a remote operations console for your codebase. Bring your own key First release philosophy: your model, your credentials. Connect OpenRouter, OpenAI, Anthropic, or account-linked flows like Codex and Claude Code. You keep control of cost, policy, and provider choice. Treena is the environment and the loop, not a locked model tax. What "done" means on mobile Done is not "the agent said something smart." Done is: - Tests green or a clear reason they are not - Diff reviewed - Commit created - Push to GitHub If those four can happen on a phone, mobile is not a niche. It is a first-class development surface. The future is pocket-scale Software is becoming less about sitting still and more about being available when the idea or the incident arrives . Agentic mobile IDEs close the gap between "I noticed it" and "I shipped the fix." That is the future Treena is building toward. Join the waitlist / waitlist , and keep your laptop optional.
