1. ReqPad — the most Postman-like, and the only one past REST

Our app, so judge the claim by its checkability: ReqPad is the only mobile API client with gRPC and Socket.IO support — across every App Store listing we checked in October 2026, no other client mentions either, and none mentions MQTT. It's also the one that behaves most like Postman itself:

• Your Postman work, intact — one-tap Postman Cloud Sync import of workspaces, collections and environments; plus Postman v2.1 files, cURL, OpenAPI/Swagger and HAR.
• Your scripts still run — pre-request and test scripts with the Postman-compatible pm.* API, and a Collection Runner with CSV/JSON data files.
• Seven protocols — REST with Server-Sent Events, WebSocket, GraphQL with subscriptions, gRPC (reflection + .proto, all streaming modes), MQTT, Socket.IO and MCP.
• ReqPad AI — explains a failing request with a one-tap fix, builds requests from plain words, writes queries and tests; secrets are removed on your device first.
• Enterprise auth — OAuth 2.0 with PKCE and auto refresh, AWS SigV4, Hawk, Akamai EdgeGrid, Digest; secrets in the Keychain.
• Everywhere you are — iPhone, iPad, Mac and Android; no account, no ads.

Honest cons: it's the newest app here, and the rating count reflects that; and the heavy protocols, scripts and advanced auth live behind Pro (REST and WebSocket are free forever, no account; 7-day free trial).

2. HTTPBot — the established all-rounder

The strongest established iOS client: 1,322 ratings at 4.48 is real, earned trust, and it's actively maintained (updated October 2026). It has grown well beyond plain REST — WebSocket, GraphQL and remote MCP servers are all in its listing now, along with Postman collection import, export and account sync. If your work is REST/GraphQL and you want maximum maturity, it's an excellent choice. Where it stops: no gRPC, MQTT or Socket.IO, and no Postman pm.* script execution or collection runner advertised. Our detailed take: HTTPBot vs ReqPad.

3. Tester — the feature-rich workspace

Formerly Teste (and API Tester before that), now listed on the App Store as "Tester – Super Intelligence". The category's install leader on Android (100K+), with REST, GraphQL, WebSocket and SOAP, collection import, Shortcuts, widgets and an Apple Watch app. If you want an all-in-one mobile dev workspace, it's a serious option. Trade-offs: no gRPC, MQTT or Socket.IO in its listing, OAuth limited to pasting an access token, and its Android build hasn't been updated on Google Play since August 2025. Details: Teste vs ReqPad.

4. Rest – HTTP API Client — simple, but dormant

A clean, minimal REST client with Postman collection file import and CloudKit sync. Well liked (4.41), but its last update was August 2022 — fine for occasional GETs, risky as a daily tool.

5. Postman in the mobile browser — the no-install fallback

web.postman.co loads on a phone and is genuinely Postman — but the layout, tap targets and the cloud Agent assumption are desktop-first. Fine for reading a collection on an iPad with a keyboard; frustrating as a daily phone tool. Full assessment in our Postman-on-mobile guide.

How to choose in 30 seconds

• You need gRPC, MQTT or Socket.IO on the move — ReqPad is the only iPhone client with any of the three.
• You rely on Postman scripts and runs — ReqPad runs pm.* pre-request and test scripts and whole collections with data files.
• Same tool on iPhone and Android — ReqPad (or Tester, if its Android build runs well on your device).
• REST/GraphQL + maximum track record — HTTPBot has earned its ratings.
• Won't install anything — Postman web in the browser, with patience.
