Deltix
Deltix is an AI agent platform that tests your iOS app by carrying out real user tasks described in plain English on a simulator, without writing test scripts.

Description
Writing and maintaining automated mobile app tests is one of those chores that teams know they should do more of but often skip, because tools like Appium or XCUITest require real scripting effort that breaks every time the UI changes. Deltix takes a different approach: you describe a user task in plain English — "sign up, add a payment method, and complete checkout" — and an AI agent actually carries it out on an iOS simulator, the same way a human tester would click through the app, then tells you whether it succeeded.
It runs in a local execution mode where your source code and app builds stay on your own machine rather than being uploaded anywhere, which matters for teams cautious about handing proprietary code to a third-party service. Beyond one-off task testing, it offers a Playbook mode to save and replay the same test flow repeatedly, and an Experiment mode for A/B comparing different app versions or flows. It also captures screenshots during test runs for later review. Deltix is currently in open beta and free to use, with no credit card required to get started.
💬 Our review
The short version: plain-English, agent-driven mobile testing is a genuinely appealing alternative to writing and maintaining brittle Appium/XCUITest scripts, and being free during open beta makes it essentially risk-free to try against a real app. The local execution mode — keeping your code and builds on your own machine — is a meaningful trust signal for teams wary of uploading proprietary mobile code to a testing SaaS.
The obvious caveat is that it's currently iOS-simulator-only and in open beta, so there's no Android support yet, no guarantee the free pricing continues once it exits beta, and AI-agent-driven testing in general is still less predictable than deterministic scripted tests for catching very specific edge cases. For teams already invested in mature scripted test suites, Deltix is complementary rather than a wholesale replacement; for teams with no mobile testing at all today, it's a much lower-effort way to start than writing Appium scripts from scratch.
