I want an app that helps golfers record and analyse their swing on both iOS and Android phones. The core of the project is accurate, frame-by-frame swing analysis: the user opens the camera inside the app, captures a swing, and then sees clear visual feedback—slow-motion playback, key angles highlighted, and comparison with previous swings stored locally on the device. A clean, intuitive interface is important; users should reach the analysis screen in as few taps as possible and scrub through the video smoothly. I am open to whichever stack you feel delivers the best real-time performance—native Swift/Kotlin, Flutter, or React Native with the right camera and computer-vision libraries—but please outline your choice and why it suits this specific task. If you have an off-the-shelf analytics engine or a custom model ready to integrate, even better; otherwise, describe the approach you would use to detect club path and body positions reliably. Deliverables • Production-ready iOS and Android builds • Full, well-commented source code • Short setup & maintenance guide so I can run future builds myself Please include a brief note on similar video-analysis or sports-tracking projects you have shipped and the libraries or frameworks you used. I will shortlist based on proven experience with high-performance camera apps and clear, maintainable code.

Hi, This is Elias from Miami. I checked your project description and understand you want a mobile app for iOS and Android that lets golfers record swings directly in-app, review them frame by frame, and analyze motion with smooth playback, visual angle feedback, and local comparison against previous swings. I’ve worked on camera-heavy mobile apps and performance-sensitive flows before, including projects where smooth video capture, frame processing, and clean UX were critical. For approach, I’d recommend a native-focused architecture for this use case, or Flutter with native camera/CV bridges if you want one shared codebase, because swing analysis depends heavily on low-latency capture, precise frame access, and reliable on-device processing. I’d keep the flow minimal: capture, process, analyze, compare, with local storage and a codebase structured for easy future model upgrades. I’d be happy to go through the details and suggest the best technical approach. I have a few questions to get a better understanding: Q1 – Do you want the swing analysis to run fully on-device, or are you open to a backend-assisted CV pipeline for heavier pose or club-path processing? Q2 – Should the first version focus on body-pose/angle analysis only, or do you also want club tracking and path detection included from the MVP stage? Looking forward to hearing from you.

Hi, Capturing the split second mechanics of a golf swing requires a high frame rate architecture and precise Computer Vision processing. At Plan D Studios, we bring 12+ years of experience in Mobile App Development, specializing in native performance to ensure video scrubbing remains fluid and analysis stays "buttery smooth." My Technical Approach: The Stack: I recommend Flutter with custom C++ Native Modules. This allows for a unified UI while leveraging native camera APIs for high FPS capture and OpenCV or MediaPipe for real time pose estimation. Swing Analysis: I’ll implement a custom model to detect 33 key body points and the club path, enabling automated drawing of swing planes and joint angles directly over the slow motion playback. High Performance UX: A "Zero Latency" video player built with hardware acceleration, allowing golfers to scrub frame by frame with zero lag. Local Comparison: A split screen overlay feature to compare current swings with "Gold Standard" sessions stored on the device. We handle all iOS Development and Android App Development in house to ensure elite code quality. Regarding the analysis: Would you like the app to automatically trigger the recording based on the sound of the club impact, or should the user manually start and stop each capture? Regards, Haider

Good to see this project, I will deliver production-ready iOS and Android builds of the swing analyzer — camera capture, frame-by-frame playback with scrubbing, angle overlays on key joints, and local swing history with side-by-side comparison. I will use Flutter with the camera plugin for capture and Google ML Kit Pose Detection for body landmark tracking. ML Kit runs on-device with low latency, giving reliable joint positions without a cloud round-trip. From those landmarks, I will calculate club path, hip rotation, and shoulder angles per frame — rendering them as real-time overlays on the slow-motion timeline. Flutter's Skia engine handles the smooth scrubbing and drawing without dropping frames on mid-range devices. Looking forward to your response. Best regards, Kamran

Hello For this project, I recommend a native approach (Swift for iOS + Kotlin for Android) to ensure maximum camera performance, low-latency processing, and precise frame control—something cross-platform frameworks often struggle with in real-time video analysis. For swing detection and body tracking, I’ll integrate MediaPipe Pose, combined with custom logic (and optional OpenCV enhancements) to calculate key metrics like spine angle, hip rotation, and swing plane. The app will work fully on-device (offline) and store swings locally for instant comparison. Please consider me and initiate a chat for further detailed discussion. Regards, Anju

Frame-by-frame swing analysis fails most often at capture quality and timeline scrubbing—if frames drop or decoding lags, angle detection becomes unreliable and UX breaks. I’d build this natively (Swift + Kotlin) to guarantee consistent high-FPS capture (60–120fps where supported) and precise frame access. Video is recorded using device-level camera APIs, stored locally, and processed frame-by-frame with a lightweight pose estimation model (MediaPipe or a CoreML/TFLite variant). Keypoints (shoulders, hips, wrists, club proxy) are extracted per frame, then angles and swing path are derived deterministically. Playback uses a custom frame buffer to ensure smooth scrubbing without re-decoding overhead. I’d also cache computed metrics per video to avoid reprocessing and enable instant comparison between swings. I’ve built similar video pipelines in Aras (Python/PHP), handling frame-accurate processing and low-latency playback, improving analysis speed by ~40%. Happy to walk through a working architecture before starting. Q1: Do you require real-time analysis during recording or post-capture only? Q2: Should swing comparisons include overlay alignment or just metric-based comparison? Q3: Any target devices or minimum FPS requirements we must guarantee?

Hello, I can build your golf swing analysis app for iOS and Android with a strong focus on high-performance video capture and smooth frame-by-frame analysis. With 8+ years of experience, I’ve worked on camera-based and real-time applications, and I recommend using a cross-platform approach (React Native) combined with native modules for camera and computer vision to ensure both performance and scalability. Proposed approach: • Use high-performance camera libraries for smooth video capture • Implement frame-by-frame playback and slow-motion controls • Apply computer vision (OpenCV / MediaPipe) to detect body posture and swing angles • Highlight key angles and swing paths visually • Store and compare swings locally for progress tracking • Ensure a clean, minimal UI so users reach analysis quickly Why this approach: React Native allows a single codebase for both platforms, while native integrations ensure real-time performance for video processing, which is critical for this app. Deliverables: • Production-ready iOS (.ipa) and Android (.aab) builds • Full well-documented source code • Setup and maintenance guide for future builds I focus on building fast, intuitive, and accurate video analysis experiences with clean, maintainable architecture.

Hi there, I will build your golf swing analyzer for iOS and Android with in-app video capture, smooth frame-by-frame playback, angle overlays, and local swing history for side-by-side comparison. For this type of app, I would use native Swift and Kotlin because camera control, frame access, and playback performance are stronger for high-speed analysis than a shared layer. I have handled camera-focused mobile work with frame processing and would use pose detection plus tracked swing checkpoints to keep feedback fast and consistent on-device. Questions: Do you want body-angle analysis only, or club path tracking as well? Should past swings stay only on the device, or also sync to a backend? Do you want support for external slow-motion videos too? Looking forward to talking through the details. Faizan
