Kilo Code App is the mobile companion for Kilo Code, the open source agentic engineering platform. Code, monitor, and steer your agents from your phone, wherever you are. WHAT YOU CAN DO → Code from your phone with Cloud Agents Spin up a Kilo Cloud Agent, give it a task, and review its work from the chat. Full agentic coding, backed by Kilo's managed infrastructure, without opening a laptop. → Connect to your desktop sessions Pair with a Kilo session running in Kilo CLI or VS Code on your computer. Send instructions, review diffs, and keep an eye on long-running tasks while you're away from the desk. → Watch your agents in real time See sessions running outside the app — CLI, IDE, Slack, or cloud — in a live read-only view. Know what your agents are doing, even when you can't intervene. → Review pull requests Paste a GitHub PR link to see checks and full file diffs with syntax highlighting. Leave line-level comments, batch them into a review, approve, reply in threads, and merge. → Work by voice, or from anywhere Dictate prompts instead of typing. Queue follow-ups while an agent is working. Attach any file type. Share links, text, and files into Kilo from any app's share sheet. → Get pinged when an agent needs you Push notifications when a session needs input, hits a milestone, or your balance runs low. An "Active now" tray keeps live sessions at the top with NEEDS INPUT badges. ALSO IN THE APP → Code Reviewer for GitHub, GitLab, and Bitbucket, with a model per repository → Security Agent: posture dashboard, findings to triage, and policy settings → Organizations: members, roles, usage limits, credits, and invoices → Context pressure and session cost in the chat header, with a per-model token breakdown → Sign in with Apple, Google, or a one-time email code → Light, Dark, or System theme WHY KILO → 500+ AI models supported Premium, free, open-source, and open-weight models.

The Abyss
Read full descriptionHide full description
The Abyss is the iOS companion for Hermes - your self-hosted AI agent running on your own machine. Connect over your local network or Tailscale, send prompts, watch the agent think and reach for tools in real time. The Abyss is a remote control. Hermes is the brain. You own both. Built for people who already host their own things. CHAT - Live token streaming. Watch the agent's reply appear as it's generated. - Transparent tool calls. See the agent reach into your shell, files, or the web - with each tool's name and arguments shown as a card. - Multimodal. Attach images from the photo library and send them with your prompt. - Slash commands. Trigger agent-side commands from a clean, keyboard-friendly composer. VOICE MODE - Hands-free conversation. Dictate prompts and hear the reply spoken back. - On-device transcription. Your voice is transcribed locally; the text is what gets sent to your agent. - Bring-your-own TTS. If your Hermes backend streams text-to-speech, you hear the agent in a neural voice; otherwise it falls back to iOS voices. SESSIONS - Server-side history. Every conversation lives on your own Hermes server, not ours. - Searchable, renameable, pinnable. Find the thread you need, give it a name, keep it on top. - Local cache. Scroll the transcript even when you're offline. MULTIPLE BACKENDS - Run more than one Hermes instance? Add them all. Switch active with one tap. - Pair a second device by scanning a QR code. Credentials never cross our servers - we don't have any. - Each backend gets its own identity colour so you always know which agent you're talking to. DEMO MODE - Not running Hermes yet? Try the demo. A scripted preview shows how the real client behaves, without any setup. No account, no network, no obligation. PRIVACY-FIRST BY DESIGN - All credentials live in iOS Keychain. Face ID required before revealing or sharing them. - No analytics. No third-party SDKs. No telemetry. - The Abyss only talks to the backends you point it at. Apple processes any future purchases; that's the only third party in the loop. - App data flows between your device and your own Hermes backend. Nothing else. REQUIREMENTS - A running Hermes Agent on a machine you control. - Network reachability to that machine. Same Wi-Fi works; Tailscale (or another mesh) is recommended if you want to reach the agent from anywhere. The Abyss is not a hosted AI service. It is a remote control for an AI agent you host yourself.

Verdict
The clearest difference is in-app purchases: The Abyss at none against Kilo Code's 3. Kilo Code's advantage is iOS requirement (16.4 vs 26.5). On price, update cadence, ads and device support there is nothing between them.
