I build iOS apps (Swift/SwiftUI, shipped to App Store) so I'm very familiar with TestFlight, provisioning profiles, and the whole beta testing flow from the developer side. That actually makes me a better tester -- I know what logs and screenshots are useful vs. what's noise. I'm based in LA, have an iPhone 15 Pro on T-Mobile postpaid, running iOS 18. I've used TestFlight plenty of times both as a developer distributing builds and as a tester on other people's projects. Comfortable with step-by-step test scripts, capturing screenshots at each stage, and reporting results clearly in real time over chat. What you'd get: someone who won't need hand-holding on the install or setup, who understands what call screening activation actually does under the hood (CallKit, call directory extensions), and who can give you useful bug reports instead of just "it didn't work." If something breaks during a session I can tell you roughly where -- the app layer, the carrier side, or iOS permissions -- which saves your dev team debugging time. Early morning or evening slots work for me. I can start as soon as you send the TestFlight invite -- no ramp-up needed. Want to kick off a quick test session this week?

Hi, I’m excited about the opportunity to test your iOS call-screening app. I have active lines on both AT&T and T-Mobile, and I’m using an iPhone 14 running the latest iOS version.

I can be available during early morning or evening US time slots, ensuring responsive communication on Slack throughout the sessions.

The worst case is you walk away with a free consultation from me about your project. Regards, Maanie786

I recently helped a tech team validate an app's functionality across various devices and networks, making sure everything ran smoothly. I can assist in testing your iOS call-screening app to ensure it performs well on major US carriers. I see you need testers for AT&T, T-Mobile, and Verizon. I have active lines on both AT&T and T-Mobile, ready to go for the live sessions during early morning or evening slots. With my experience in QA and app testing, I can provide clear feedback while capturing detailed screenshots at each step. First, I’d focus on ensuring the installation process is seamless and the call screening feature works flawlessly. I'm available to start immediately and would love to discuss further. When works for you? Kind Regards, Anchel.

I HAVE RECENTLY FINISHED A SIMILAR PROJECT where I tested a call screening app across different carriers, ensuring it performed seamlessly. I understand the importance of verifying functionality on AT&T, T-Mobile, and Verizon, especially with the various network conditions users may face. My approach emphasizes clear communication and thorough documentation, ensuring that each testing phase is executed smoothly. I noticed your emphasis on capturing screenshots during call notifications, which is crucial for validating user experience. I have experience with TestFlight and currently use an iPhone 13 on AT&T, making me well-suited for this role. I would love to discuss the project further and clarify any details needed to proceed. Regards, Jeandre.
