Termopus App

Native mobile interface for controlling Claude Code

The Termopus mobile app is a purpose-built native interface for Claude Code. It renders every action Claude takes in real time — code diffs, file edits, terminal output, and error logs — in a scrollable conversation thread with full syntax highlighting.

All cryptography runs in native Swift (iOS) and Kotlin (Android). The Dart UI layer never touches encryption keys.

• WhatsApp-style conversation thread showing Claude's output as it happens
• Syntax-highlighted code blocks, inline diffs, collapsible tool-use cards
• Interactive action buttons: Allow, Deny, Edit, Always Allow
• Active agent indicators and task progress tracking

• Every approval gated behind biometric authentication (Face ID / Fingerprint)
• Smart "Always Allow" — learns patterns and auto-writes permission rules
• AskUserQuestion intercepted and rendered as interactive cards on phone

• Line-by-line file change inspection before execution
• Color-coded additions, deletions, and modifications
• Collapsible diff viewer with full syntax highlighting

• Pair with work laptop, home desktop, and cloud VMs simultaneously
• Each session independently encrypted with hardware-backed keys
• Project-grouped session picker — tap to switch, swipe to delete

• Silent FCM push when Claude waits for input
• Notification includes request context for quick triage
• Auto-wake and reconnect on tap

• 5 breakpoints covering phones through tablets
• Adaptive typography, spacing, and icon sizing
• Terminal mode toggle — chat bubbles or terminal-style feed
