Everything You Need

Professional API testing tools, designed for mobile.

PRO

Endpoint Monitoring

Mark a saved request as watched and ProbePad runs it in the background, then tells you when it starts failing. It shows when the last check happened — iOS decides when the next one is granted.

Free + PRO

Home & Lock Screen Widgets

Last Request and Request Status on your Home Screen, plus a Lock Screen circular — all free. The Endpoint Monitor widget, showing a watched endpoint's last result, is PRO.

Free

Spotlight Search

Your request names and hosts are searchable straight from the Home Screen. Tap a result to open it. Secrets and environment values are never indexed, and you can switch indexing off.

Free

Cancel a Running Request

One tap stops an in-flight request and tears the connection down. The cancelled attempt still lands in your history.

Free

Find in Response & Cookie Replay

Search inside a response body with a live match count, copy a single header value, and send a returned Set-Cookie straight back as a request header.

Free

cURL Import — Free

Paste a cURL command, get a request. Free for everyone, and staying free — bulk Postman and OpenAPI imports are the PRO ones.

HTTP Requests

GET, POST, PUT, PATCH, DELETE with full header and body control. Multipart/form-data with file upload built in.

GraphQL

Dedicated query editor with variables, operation names, and pretty-printed responses. Run queries, mutations, and subscriptions.

WebSocket

Open WebSocket sessions, send text and binary frames, and inspect every message in a live transcript.

Collections & Environments

Group requests into named, colour-coded collections. Switch between dev, staging, and production with one tap.

Secrets Vault

Store API keys securely in the iOS Keychain with Face ID / Touch ID protection. Secrets never leave your device.

Response History & Diff

Compare responses with JSON diff. Track status, latency, and payload changes over time.

Siri & Shortcuts

"Run Saved Request" and "Send HTTP Request" App Intents for Siri, the Shortcuts app, and Focus automations.

Import & Export

Import Postman v2.1 collections, paste cURL commands to create requests, and export back to cURL.

What's New

Endpoint Monitoring (PRO)

Mark a saved request as watched and ProbePad runs it in the background, then notifies you when it starts failing. The app tells you when the last check happened.

Widgets

Last Request and Request Status on the Home Screen, Request Status as a Lock Screen circular, and Endpoint Monitor (PRO) showing a watched endpoint's last result.

Spotlight

Request names and hosts are searchable from the Home Screen; tap a result to open the request. Secrets and environment values are never indexed, and there is a switch for it in Settings.

Cancel a Running Request

One tap stops an in-flight request and tears the connection down. The cancelled attempt is written to history.

Find in Response & Cookie Replay

A find bar over the response body with a live match count, one-tap copy of a header value, and a returned Set-Cookie sent straight back as a request header.
