Thanks for testing AnesCalc — a few minutes of feedback directly shapes the next build.
The quickest route is TestFlight: take a screenshot in AnesCalc and tap Share Beta Feedback, or open the TestFlight app, choose AnesCalc, and tap Send Beta Feedback. If that isn't working for you, use this form instead — it goes straight to the developer.
Your feedback was sent. It genuinely shapes what gets fixed and built next.
