Azure Key Vault, without the portal: KeyVault Studio is the native client for Mac, iPhone and iPad. Your secrets, keys and certificates are well protected in Azure. Managing them just takes too many clicks in the portal. KeyVault Studio turns that into a real Apple app: fast, focused and secured with Face ID / Touch ID. Want to look around first? Demo mode opens the complete app with sample data, no Azure account needed. SECRETS ▸ Create, view, update and delete, every value behind Face ID / Touch ID ▸ Full version history with side-by-side comparison ▸ Content types for JSON, XML, connection strings and API keys ▸ The app warns before anything expires, with thresholds you choose ▸ Copied values clear themselves from the clipboard KEYS ▸ Create RSA, EC and HSM-backed keys ▸ Crypto Playground: encrypt, decrypt, sign, verify, wrap, unwrap ▸ Rotation policies and one-tap rotation ▸ Import from JSON Web Key CERTIFICATES ▸ Issue self-signed and CA-signed certificates ▸ Import PFX/P12 and PEM, export the public certificate or the private key ▸ Manage policies, issuers, contacts and pending operations NETWORKING ▸ Configure the vault firewall, VNet rules and private endpoints ▸ Manage private DNS zones, record sets and VNet links ▸ Approve or reject private endpoint connections VAULTS ▸ Find vaults across all your Subscriptions in seconds ▸ Create a new vault with a guided wizard ▸ Backup and restore, AES-GCM encrypted if you want ▸ Recover or purge soft-deleted vaults and items AI ASSISTANT ▸ Ask questions about your own infrastructure: what expires soon, what is disabled ▸ Runs fully on device if you want: Apple Intelligence or Gemma, no cloud required ▸ Or bring your own key: Claude, OpenAI, Gemini, plus Ollama on your own network ▸ Naming suggestions per Cloud Adoption Framework, subnet and address space planning ▸ The assistant sees names and metadata, never secret values ▸ A visible token budget keeps API costs under control BUILT FOR APPLE PLATFORMS ▸ Mac, iPhone and iPad with the same feature set, tuned per size class ▸ Lightning-fast search across every vault and item, right on the device ▸ Several accounts side by side: Azure Commercial, US Government and China clouds ▸ No middleman servers: the app talks directly to Azure with your Microsoft Entra ID sign-in Bring your own app registration or use the built-in one.

Difftray brings code review to your phone and tablet. Pair it with the open-source Difftray desktop app, then read git diffs, browse every changed file, and leave line-by-line comments — all over your own local network, with no cloud in between. Difftray is a companion app. It works alongside the Difftray desktop app running on your Mac. Scan a QR code once to pair, then pick up any project from the couch, a meeting room, or the other side of the office. REVIEW DIFFS ANYWHERE Read inline diffs with real syntax highlighting, sized for small screens. See additions and deletions at a glance, move between changes, and mark each file reviewed as you go. BROWSE CHANGED FILES Step through every changed file in a project and see exactly what moved, with per-file and total added/removed line counts. HAND OFF TO YOUR CODING AGENT Leave comments on the lines that need work, then export them as an agent-ready prompt. Copy it or share it straight into your AI coding agent so the fixes are queued up before you're back at your keyboard. ALL YOUR PROJECTS Every project open on your desktop is one tap away on your phone or tablet. PAIR LOCALLY, STAY PRIVATE Connect by scanning a QR code or entering a short code — no account, no sign-up. Your phone talks directly to your own computer over local Wi-Fi, or over your private Tailscale network when you're away from your desk. Pairing is end-to-end encrypted, and your code never touches a server we run. REQUIREMENTS Difftray requires the free, open-source Difftray desktop app with its companion server enabled. This mobile app is a companion to that desktop app and does not work on its own. Pair your phone, step away from your desk, and keep reviewing.
