Deltix

Deltix tests a mobile app the way a user would: you describe a task in plain English, and an AI agent runs it on an iOS simulator on your Mac, then reports whether a real user could complete it. Successful runs can be saved as regression checks and replayed later. The agent runs locally, so your source, build and signing identities stay on your machine; the service is in open beta, currently iOS only, and you can bring your own model key.
