iOS Finger Chooser Clone

I need an iOS app that visually and audibly mirrors the ios-only “Chwazi Finger Chooser” so closely that, when my version and the original sit side-by-side, no one can spot the difference. Every detail—timing, haptic feedback, sound cues, and fluid movement—has to feel identical.

Core behaviour
• Detect between one and six fingers on the screen.
• Instead of random selection, the finger whose touch point is nearest to coordinate in the left upper corner of a phone must always win be selected .
• The original “group” feature can be left out.

Critical visual polish
The three hallmark animations must look and behave exactly as in Chwazi:
• Circle Selection Animation
• Finger Detection Animation
• Winner Announcement Animation

Audio & haptics
Use the exact same selection and winner sounds the Android version employs, matched in volume and timing, plus identical vibration feedback.

Platform & delivery
This is strictly an iOS build. Please supply a TestFlight link for hands-on testing and the full Xcode project so I can archive future builds myself. I’m open to Swift, Flutter, React Native—whatever lets you replicate the experience pixel-perfectly and efficiently.

Acceptance criteria
1. Side-by-side visual and audio indistinguishability from the reference app.
2. Deterministic winner logic based on proximity to (0, 0).
3. Smooth performance on current iPhone models.
4. TestFlight build and clean, well-documented source code provided.
