1. Project Overview & Goal We are seeking a skilled iOS Developer (Swift/Objective-C) to create a simple, elegant mobile application that functions as a highly customizable speaking clock or hourly chime replacement. The core goal is to audibly announce the current time on the hour using high-quality, non-digital, human voice recordings, with flexible user controls. 2. Core Feature Requirements The final delivered product must include the following functionality: A. Time Announcement Logic • The app must run reliably in the background (using appropriate iOS background execution features) and announce the time exactly on the hour (e.g., at 1:00 PM, 2:00 PM, 3:00 PM, etc.). • The announcement must be played at the system volume level, or a volume level independent of the system media player if feasible and better for user experience. • The announcement should be in the format: "It is [Hour] o'clock" (e.g., "It is five o'clock"). B. Customizable Voice Selection • The app must include pre-recorded, non-digital, human-sounding voice assets for the announcements. • The user must be able to select between two distinct voices (Male or Female) within the settings. • Note to Freelancer: I will provide the high-quality pre-recorded audio files for the numbers (one through twelve) in both the male and female voices upon project award. C. Hourly Schedule Control (Key Feature) • The user must have granular control over which hours the announcement is active. • This must be implemented as a 24-hour schedule (12 AM to 11 PM) with individual toggles for each hour. • Example: The user can toggle ON announcements for 8 AM, 9 AM, 5 PM, and 6 PM, but leave the rest of the day OFF. 3. Technical Requirements & Deliverables A. Platform & Technology • Platform: iOS (latest stable version). • Development Language: Swift is preferred. • Target Devices: iPhone (Universal app). B. Deliverables 1. Fully functional, tested, and ready-to-publish iOS application package. 2. Complete, clean, and well-commented source code (via a GitHub repository or similar) which I will own 100%. 3. Documentation on setting up and compiling the source code. 4. All necessary design assets (icons, UI elements, etc.). 4. User Interface (UI) Requirements The UI should be clean, modern, and simple. It needs two main screens: 1. Home/Status Screen: Displays the current time and a master ON/OFF toggle for the entire service. 2. Settings/Schedule Screen: • Voice Selection (Radio button/Segmented Control): Choose Male or Female. • 24-Hour Schedule List: A list view or matrix with 24 rows/toggles labeled clearly (e.g., 12 AM, 1 AM, ..., 11 PM) for activation control. 5. Selection Criteria (What to Include in Your Bid) Please ensure your proposal addresses the following: • Your experience with iOS background audio/task execution and dealing with iOS system limitations for scheduled tasks. • The estimated timeline for completion. • Confirmation that you understand the requirement for 100% source code ownership transfer upon completion. • Confirmation that you can integrate the provided external audio files seamlessly. We look forward to reviewing your proposals and selecting a developer who can deliver a reliable, polished application.

Hello! I can build your iOS speaking-clock app with reliable background execution, precise hourly announcements, and seamless integration of your pre-recorded human-voice audio files. I’ve shipped multiple Swift apps that rely on background audio, scheduled triggers, and clean UIKit/SwiftUI interfaces — so handling iOS’s background constraints and ensuring the chimes fire exactly on the hour won’t be an issue. What I’ll deliver • Swift-based iOS app that announces the time on configured hours • Background-safe scheduling using approved iOS audio/background modes • Male/Female voice selection with your provided audio assets • 24-hour granular schedule with individual toggles (12 AM → 11 PM) • Clean 2-screen UI: Home (master toggle + time) + Settings (voice + schedule) • App Store–ready build + all icons/assets • 100% source code ownership (Git repo) + setup documentation Experience Worked extensively with: background audio, local scheduling logic, AVAudioSession, Swift concurrency, and reliable time-accurate triggers. If this aligns with what you’re aiming for, I can start immediately and outline the full implementation plan. Best regards, Jasmin.

I can build your speaking-clock iOS app exactly as specified, using Swift and following Apple’s latest background audio rules to ensure reliable hourly announcements. I’ve worked extensively with background tasks, audio playback, and scheduling on iOS, so implementing an hourly chime system with user-controlled 24-hour toggles will be straightforward. I can integrate your provided male/female voice recordings, build a clean UI with a master switch, voice selector, and per-hour schedule, and ensure the app plays high-quality audio precisely on the hour. You’ll receive a fully tested, publish-ready build plus 100% source code ownership with clean, well-commented implementation and setup documentation. I can also advise on best practices for long-running audio services within iOS limitations. Timeline will be efficient, and I can deliver incremental builds as needed. I’ll share portfolio examples during the interview.

Hi, I'm an experienced iOS developer specializing in Swift, with deep knowledge of background audio handling and scheduled task execution on iOS. I understand the challenge of reliably triggering audio announcements at exact hourly intervals, especially under iOS’s background limitations — and I will leverage AVAudioPlayer, Background Modes, and local notifications for robust execution. I can seamlessly integrate your provided human-voice audio files and offer a smooth toggle-based 24-hour schedule UI. Managing per-hour user preferences and dynamic voice switching will be modular and cleanly coded. I'll also ensure volume handling respects the user experience while maintaining system compliance. The UI will be minimalist and intuitive, with complete source code and documentation delivered as requested. Thanks, Hercules

Hey, i will create the speaking-clock app in swift using xcode with background audio modes enabled so the app can run time checks on the hour and play the provided pre-recorded voice clips through avaudioengine at system volume or an app-controlled level, while a scheduled timer synced with the system clock triggers announcements only for the hours selected by the user; the interface will have a minimalist home screen showing the current time with a global on/off switch, and a settings screen using a segmented control for male/female voice selection plus a scrollable list containing 24 toggles mapped to 12 am through 11 pm, each linked to userdefaults so preferences persist across sessions; the audio files for hours one through twelve will be organized in asset catalogs and referenced dynamically based on the current hour modulo twelve, and the background execution will rely on audio session categories and periodic wake strategies that stay within ios policy; once the app logic, ui, and hourly scheduling are confirmed on real devices, i will prepare an app-store-ready build, deliver all swift source code in a repository, provide setup notes for compiling and signing, and include the required design assets. Let's have a detailed discussion, as it will help me give you a complete plan, including a timeline and estimated budget. I will share my portfolio in chat Looking forward to hearing from you through chat. Thanks Best Regards, Mughira

Hello. The critical factor here is bypassing iOS background execution limits to guarantee the chime plays *exactly* on the hour, rather than approximately. Are you open to using Local Notifications with custom audio payloads to maximize battery life, or are you strictly requiring a background audio player mode? Additionally, regarding the audio assets, do you need assistance normalizing the volume levels between the male and female recordings before integration? I will develop this natively in Swift, prioritizing a "set and forget" architecture. I will create a logic controller that maps your 24-hour toggle list directly to the system's notification center or audio session, ensuring the app respects the specific hours selected and plays the correct file even when the app is backgrounded. The UI will be intuitive, matching your two-screen requirement (Home/Status and Schedule), and I will ensure the audio integration handles the transition between voices smoothly. I fully confirm and agree to the 100% source code ownership transfer upon completion. I am a Senior iOS Engineer with extensive experience in AVAudioSession and background task scheduling, ready to deliver a polished, publish-ready application.
