We make ReqPad, so discount accordingly — and check every row yourself. Teste is the category's install leader and earned it; this is about which tool fits which developer.

Teste wins on breadth of workspace and platform reach. Scripts and a terminal next to your requests is a genuinely different proposition — closer to "pocket dev environment" than "API client" — and it's available on Android right now, where ReqPad isn't yet. The install base says plenty of developers want exactly that. (As with any app, scan the most recent reviews for your specific device before relying on it in production on-call.)
ReqPad wins on protocol depth. Where Teste goes wide across tools, ReqPad goes deep on the API layer itself: six protocols including the two no other mobile client covers (gRPC, Socket.IO), GraphQL subscriptions, MQTT with QoS, nine auth schemes, and your existing Postman workspaces imported in one tap. If "debugging APIs" rather than "general dev tasks" is the job, that depth is the difference.
Wider context: best Postman alternatives for iPhone and why there's no Postman mobile app.
Yes — the app formerly known as API Tester (apitester.org) rebranded to Teste. It is the category install leader, with 100K+ downloads on Google Play and a 4.72 rating on the App Store.
If you want an all-in-one mobile workspace — HTTP requests plus scripting and a terminal — or you need an Android app today. Teste ships on both platforms; ReqPad is iOS/iPadOS/macOS with Android in development.
When protocol coverage decides it: ReqPad handles GraphQL, gRPC, MQTT, WebSocket and Socket.IO alongside REST — ReqPad is the only mobile API client with gRPC and Socket.IO support. Likewise if you want one-tap Postman workspace import or auth schemes like AWS SigV4, Hawk and EdgeGrid.
REST & WebSocket free forever, no account — and gRPC, MQTT, GraphQL & Socket.IO behind a 7-day Pro trial.
