WinCome Sports tournament app for iOS and Android

Win Bracket Context

Tournament context for App

The WinCome Sports app is the fastest way to manage your tournament brackets, calibrate captain picks, and track live scoring from your phone. The app is built native on iOS and Android, with offline draft support and a one-second push notification latency during live matches.

The WinCome Sports app is built native, not wrapped in a web view. The result is a 1-second push latency during live matches, a 38 MB install size, and a 4.9/5 rating from 412,000+ verified players. The next tournament bracket you enter will probably come from this app — and the captain-pick calibration is waiting for you inside.

The WinCome Sports app architecture on iOS and Android

The WinCome Sports app is built native on iOS and Android. The iOS app is written in Swift with SwiftUI for the UI and Combine for the live scoring pipeline. The Android app is written in Kotlin with Jetpack Compose for the UI and Coroutines + Flow for the live scoring pipeline. The shared business logic is implemented in C++ and shipped as a platform-specific library on each platform. The C++ shared library contains the scoring engine, the captain calibration model, the wallet system, and the user authentication. The library is compiled to iOS (arm64) and Android (arm64-v8a, armeabi-v7a, x86_64) architectures. The library is 8 MB on iOS and 10 MB on Android. The library is loaded at app launch and stays in memory for the lifetime of the app. The app uses platform-specific push notification systems: APNs on iOS, FCM on Android. The push notification latency is <1 second during live match windows. The push notification is triggered by the live scoring engine when a notable event happens: a wicket, a fifty, a century, a captain pick re-ranking, a win bracket leaderboard change. The app supports offline bracket drafts. The user can build a team, pick a captain, and save the team to the local device. The team is submitted to the platform as soon as the device reconnects to the network. The offline draft is useful for users who want to plan their team in advance of a match but do not have reliable connectivity at the time.

The 4 features that make the WinCome Sports app unique

Feature 1 is the 1-second push notification latency. The app uses platform-specific push notification systems (APNs on iOS, FCM on Android) and a custom routing layer that bypasses the standard FCM/APNs delays. The custom routing layer reduces the latency from 5-10 seconds (standard) to <1 second. The result is that the user gets the live scoring update almost as fast as the commentator announces it. Feature 2 is the offline bracket draft. The app supports building a team and saving it to the local device, even when the device is offline. The team is submitted to the platform as soon as the device reconnects. The offline draft is useful for users who want to plan their team in advance. Feature 3 is the native C++ scoring engine. The scoring engine runs on the device, so the user can see the live score update even if the network connection is slow. The on-device scoring engine is also used to verify the server-side scoring: if the on-device score and the server-side score differ, the user is notified and the discrepancy is reported to the platform team. Feature 4 is the 5-device trusted device list. The user can mark up to 5 devices as trusted. Trusted devices skip the 2FA prompt for 30 days. The user can revoke a trusted device at any time. The 5-device list is useful for users who have a phone, a tablet, a work phone, a personal laptop, and a work laptop.

Path 2 is the Android Google Play. The app is published under the package name com.wincomesports.bracket. The app supports Android 10 and above. The app is optimized for phones and tablets. The app size is 38 MB. The app supports 4 device architectures: arm64-v8a (most modern phones), armeabi-v7a (older phones), x86_64 (Chromebooks), and x86 (emulators). Path 3 is the Android APK. The APK is the official install path for users outside Google Play. The APK is signed with the WinCome certificate (SHA-256 published on the download page). The APK supports Android 10 and above. The APK size is 42 MB. The APK supports the same 4 device architectures as the Google Play version. Path 4 is the Android HarmonyOS. The app is available on the Huawei AppGallery. The package name is com.wincomesports.bracket.hms. The app supports HarmonyOS 3.0 and above. The app is built with the HMS Core SDK. The app size is 44 MB. The HarmonyOS version is in beta as of Q2 2026.

The 4 platform support paths are unified by a single C++ business logic library. The library contains the scoring engine, the captain calibration model, the wallet system, and the user authentication. The library is compiled to all 4 target platforms: iOS (arm64), Android (arm64-v8a, armeabi-v7a, x86_64), and HarmonyOS (arm64). The library is 8-10 MB depending on the platform. The user experience is identical across all 4 paths. The UI is platform-specific (SwiftUI on iOS, Jetpack Compose on Android, ArkUI on HarmonyOS), but the business logic, the data, and the captain-pick recommendations are identical. The user can switch between platforms smoothly: the account is the same, the wallet is the same, the bracket history is the same, and the captain-pick history is the same. The 4 platform support paths are updated simultaneously. The release cadence is 2 weeks: the iOS, Android, APK, and HarmonyOS versions all ship on the same day. The release notes are published on the news page. The release notes include the new features, the bug fixes, and the known issues. The release notes are also published in the app stores and on the HarmonyOS AppGallery. The 4 platform support paths are tested on a range of devices. The testing matrix includes 24 iOS devices, 32 Android devices, and 8 HarmonyOS devices. The testing matrix covers the most popular devices in India: iPhone 11, 12, 13, 14, 15; Samsung Galaxy A14, A24, A34, A54; Xiaomi Redmi Note 12, Note 13; Realme Narzo 60, Narzo 70; Huawei P50, P60, Mate 50, Mate 60. The testing is automated with Appium and runs on every release.
