Hi, Since the app is already live, I would start by reproducing and isolating the current bugs before changing architecture or UI unnecessarily. For sports apps, issues around live-score/odds APIs, stale state, authentication and asynchronous updates can easily appear related while having different root causes. My background includes iOS/mobile development, production debugging, real-time API integrations and secure user-account workflows. I can review the existing codebase, reproduce the reported issues, fix the underlying causes, and regression-test the Football/Basketball flows across representative devices. I’ll also verify that live data refresh, account sessions and UI state remain stable after the changes. For the initial maintenance sprint: Budget: $350 USD. Timeline: 4 days. I can start immediately after award and provide a concise summary of each issue, fix and test result.

Live scores, betting odds, and user accounts are exactly the parts of a sports app where small bugs can quickly turn into trust issues for users. For this kind of iOS maintenance work, I’d start by isolating whether the problems are coming from the UI layer, real-time data sync, or auth/session handling so fixes are stable rather than temporary patches. I’ve worked on app troubleshooting where the main challenge was not just fixing visible bugs, but making sure live data, account flows, and app behavior stay reliable after updates. That matters even more in betting-style apps, where delays, wrong odds display, or login/account issues can directly affect user retention. If you share the current bug list, I can map the fastest fix path for you. - Are the current issues mainly in live score/odds updates, login/account handling, or crashes/UI behavior? - Is the app native Swift/SwiftUI/UIKit, or built in another stack for iOS delivery? - Do you also need help reviewing the current API/data integration for stability?

Your iOS sports betting app needs focused maintenance of its existing bug issues, while keeping football and basketball coverage, live scores, betting odds, and user accounts reliable. I can first reproduce each issue on the relevant iOS versions, review crash logs and API responses, then trace the problem through the UI, authentication flow, and real-time data layer before applying targeted fixes and regression testing. I work with native Swift and Objective-C, and can safely update an existing codebase without disrupting working features. For live-data reference, I recently fixed a trading platform whose price charts were freezing because its Twelve Data integration was unthrottled. I added caching, API credit controls, and a last-good-price fallback—an approach that translates well to live scores and odds feeds. I can also review secure session handling, Keychain storage, loading/error states, and odds refresh behavior so users are not shown stale or misleading data. I’ll provide a concise bug-fix summary with the cause and resolution for each issue, plus a tested build for review. Do you already have a reproducible list of the current bugs, or should I begin with a full app audit? Muhammad Saad

Bugs inside a sports betting app usually come from the most sensitive areas: live data refresh, odds rendering, and account-related flows. The right approach here is to review the current iOS codebase, reproduce each issue properly, and fix the root cause so the same problems do not keep resurfacing after release. I’ve handled mobile app maintenance work where real-time feeds and authenticated user sections needed careful debugging, not guesswork. For an app like yours, experience with iOS behavior, API responses, and secure session handling matters a lot because even minor inconsistencies can damage user confidence very quickly. I can also help tighten the UX while resolving the bugs so the app feels smoother overall. - Do you already have a documented list of the bugs, or should I begin with a full QA pass? - Which sportsbook/feed provider is currently being used for live scores and betting odds? - Are these issues happening in production only, or can they be reproduced in a test build as well?

Hi, I am Ryan from San Francisco. Before quoting, two things usually explain "bug issues" on a live sports betting app more than the code itself. First: is the app already live on the App Store, or running via TestFlight/enterprise distribution? Real-money betting apps fall under Apple's gambling guidelines (3.1.1/4.7) requiring proper licensing entitlements and geofencing — some "bugs" turn out to be review/compliance rejections, not runtime crashes, and that changes the fix entirely. Second: live scores and odds usually come from a third-party feed over WebSocket or polling — most "stuck odds" or "wrong score" complaints trace back to stale connections or silent reconnect failures, not the UI layer. My plan: pull the crash logs/current build, reproduce the reported bugs, and separate them into (a) data-layer issues — feed reconnects, odds not updating, score lag, and (b) app-layer issues — auth, UI, account state. I'll fix what's in scope for the budget first (whichever bucket is causing the most user-facing pain), give you a clear list of what's fixed vs what needs more time, and quote separately if anything requires deeper rework (e.g. a full auth overhaul). Quick question: is this already on the App Store, and is the live odds feed a licensed provider's API or a custom scraper? Happy to share iOS work on request. Ready to start once I have repo/TestFlight access. Best, Ryan

I can help you quickly identify and fix the bugs causing trouble in your sports betting app. Having worked on a similar project with live betting updates and secure user accounts, I’m familiar with handling real-time data feeds and ensuring smooth UI/UX under pressure. To start, it would help to know if the bugs affect live scores, betting odds updates, or user authentication specifically. Are you using any third-party services for the live data? That can influence the debugging approach. Also, continuous testing on both Wi-Fi and cellular networks often uncovers syncing issues users face. I can dive into the current codebase, isolate the buggy components, and ensure stable real-time updates for Football and Basketball. My goal will be to improve reliability without disrupting your users’ ongoing bets. Ready to jump in and get those issues resolved fast so your app runs smoothly again. Just share access and any error logs you have, and I’ll get started.
