About

ProbePad

Features
Read full description

ProbePad is the API client Postman never built for iPhone and iPad — native, private, and fast enough to ship a production fix from the couch. New in v1.6: ProbePad watches your endpoints while you sleep — background health checks with failure alerts, status widgets on your Home and Lock Screen, Spotlight search, and one-tap cancellation. ENDPOINT MONITORING (PRO) • Mark any saved request as watched and ProbePad runs it in the background • A notification when a watched endpoint starts failing, with the request name and the status it returned • A cooldown per endpoint, so a flapping service does not alert you over and over • iOS decides when background work is granted. ProbePad tells you when the last check happened, never when the next one will • If Background App Refresh is off, the app says so plainly WIDGETS — HOME SCREEN AND LOCK SCREEN • Last Request — your most recent run, with its status and when it ran • Request Status — a saved request's last status and response time. Also a Lock Screen circular widget • Endpoint Monitor (PRO) — a watched endpoint's last result, and when it was checked • A widget sees a summary only: request name, host, status, timing. Never a header, a body or a token SPOTLIGHT, SIRI AND SHORTCUTS • Request names and hosts are searchable from the Home Screen — tap a result to open it • Indexing is a switch in Settings, and secrets and environment values are never indexed • "Run Saved Request" and "Send HTTP Request" App Intents for Siri, the Shortcuts app and Focus automations • The Shortcuts result carries the request, the status and the timing CANCEL A RUNNING REQUEST • One tap stops an in-flight request and tears the connection down • The cancelled attempt is written to history, not lost ON CALL, INSIDE THE RESPONSE • Find in the response body, with a live match count and wrapping next/previous — even on truncated bodies • Copy a single header value without selecting text • Replay a returned Set-Cookie as a request header, in one tap • History rows are tagged with the environment they ran against, and a cross-environment diff warns you first BUILD & EXECUTE • GET, POST, PUT, PATCH, DELETE with full header, query and body control • Multipart/form-data with file upload • JSON, raw and form-encoded bodies • Per-request timeout (1–300 s) ORGANIZE • Collections — group related requests, colour-coded (free) • Environments and variables — switch between dev, staging and production (PRO) • Secrets Vault — API keys in the iOS Keychain, Face ID or Touch ID (PRO) INSPECT • Syntax-highlighted JSON tree • Response history with side-by-side diff (free) • Status, headers, timing and byte count AUTHENTICATION • Bearer token, Basic, API key (header or query) • OAuth 2.0 authorization code with PKCE, and client credentials (PRO) • Automatic token refresh, Keychain storage • Provider presets: Google, GitHub, Azure AD, Auth0 • JWT inspection GRAPHQL & WEBSOCKET (PRO) • GraphQL editor with schema introspection, variables and named operations • ws:// and wss:// sessions with text and binary frames, a full transcript and auto-reconnect IMPORT • cURL — paste a command and get a request. Free, and staying free • Postman v2.1 collections, OpenAPI 3.0 and Swagger 2.0 (PRO) PROBEPAD PRO Lifetime is a one-time purchase (US$19.99).
