Evidence scope: No current overall US chart position is available. Category-chart positions shown in discovery are a separate scope. Revenue is a directional model estimate, not verified earnings.
A product spec, screen plans, and build steps for your coding agent.

Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

Good fit for mobile-first iOS and Android prototypes with managed app scaffolding.

Tempest is the SSH client built for people who actually manage servers. Connect via SSH, SFTP, or Mosh. Forward ports. Transfer files. Manage Kubernetes clusters. Collaborate in real-time. All from your phone, tablet, or Mac — with end-to-end encrypted cloud sync across every device. CORE FEATURES • SSH & Mosh — Reliable connections, even on flaky networks. Mosh keeps your session alive where SSH drops. • SFTP File Manager — Browse, edit, and transfer remote files with a native file manager experience. • Port Forwarding — Set up local and remote SSH tunnels in seconds. • Storm AI (Pro) — An AI agent that plans, executes, and completes terminal tasks for you. Not a chatbot — a copilot that actually runs commands. • Real-Time Collaboration — Invite teammates into your live terminal session. Debug together, resolve faster. • Kubernetes — Sync kubeconfigs, switch clusters, manage pods with AI-assisted workflows. • Post-Quantum Cryptography — One-tap switch to PQC key exchange. Protect your connections against future quantum threats today. • Connection Multiplexing — Reuse TCP connections. New sessions open instantly as additional channels. • Hardware Security Keys — FIDO2 / YubiKey authentication via ed25519-sk and ecdsa-sk. • 1Password Integration — Pull credentials directly from your vault. SECURITY FIRST Zero-knowledge architecture. Your data is end-to-end encrypted before it ever leaves your device. Encryption keys stay on your device — we never see them. Encryption is fully open-sourced for transparency. SYNC EVERYTHING Sessions, keys, snippets, and configurations sync across major OS. Pick up exactly where you left off. PRO UNLOCKS • Background connection persistence • Biometric app lock • Server performance monitoring dashboard • Full Storm AI access • Cloud sync --- Tempest is built by engineers, for engineers.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
