ProbePad
Read full descriptionHide full description
ProbePad is the API client Postman never built for iPhone and iPad ā native, private, and fast enough to ship a production fix from the couch. New in v1.6: ProbePad watches your endpoints while you sleep ā 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 ā HOME SCREEN AND LOCK SCREEN ⢠Last Request ā your most recent run, with its status and when it ran ⢠Request Status ā a saved request's last status and response time. Also a Lock Screen circular widget ⢠Endpoint Monitor (PRO) ā 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 ā 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 ā 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 (1ā300 s) ORGANIZE ⢠Collections ā group related requests, colour-coded (free) ⢠Environments and variables ā switch between dev, staging and production (PRO) ⢠Secrets Vault ā 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 ā 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). Yearly is US$9.99 per year after a seven-day free trial and renews automatically until you cancel it in your Apple Account settings. Prices for your region are shown in the app. Bought ProbePad before v1.6? You keep PRO forever, at no charge, including everything in this release ā nothing to buy, nothing to do. PRIVACY-FIRST ⢠All your data stays on your device ⢠No analytics, no third-party SDKs, no advertising identifier, no telemetry ⢠PrivacyInfo.xcprivacy declares everything the app touches ⢠Secrets live in the iOS Keychain, never in plain text Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
