I am Sumit Joshi from Sacesta Technologies. Proposed approach and stack • Mobile app with a fully native look and feel • Option one: Flutter for a single high performance codebase with native UI tuning • Option two: SwiftUI for iOS and Jetpack Compose for Android if full native separation is preferred • Local storage with offline-first support using secure local database • Cloud sync via secure APIs so tasks stay consistent across devices • Push notifications using native notification services for due date reminders Core functionality • Create, edit, delete, and reorder tasks using drag and drop priority • Set due dates and priority levels with clear visual indicators • Local and remote notifications triggered reliably and on time • Offline access with automatic sync when connectivity returns • Clean UI aligned with Apple Human Interface Guidelines and Material Design Deliverables • iOS and Android apps ready for TestFlight and Google Play Console review • Full source code in a private repository with clear structure and comments • Setup and handover documentation for builds, notifications, and future extensions • QA checklist covering task flow, sync behavior, notifications, and offline cases Relevant work • Built workflow driven mobile and web apps where speed, clarity, and reliability were more important than feature volume

@arshig8

Having completed numerous iOS and Android app projects, I am Arshiya, a skilled and versatile freelancer. My expertise spans both the Android and iOS platforms; with experience in both Kotlin/Jetpack Compose and Swift/SwiftUI, means that I can seamlessly build your task management app natively for both operating systems. My approach to development places emphasis on user experience,e and my familiarity with Material Design and Apple Human Interface Guidelines ensures I will construct an app with a clean, responsive interface. Beyond the brief, my past experiences can contribute positively to the project roadmap - I’ve integrated calendar functionalities, note-taking features, and ensured push-notification capability on previous apps. Maintaining data securely is a priority for any app, but particularly this one, as data needs to reliably sync across devices while remaining available offline. With a deep understanding of offline persistence mechanisms, I can ensure a robust architecture that will meet this requirement with success. Equally, this would not compromise my ability to realize the 'fully native look and feel'. On completion, I will ensure swift delivery by uploading your product to Testflight and Google Play Console,e where you can have it reviewed - before handing over all source codes in a secure private repository so you retain complete control of your work.

Hi! I’m Tarang, I am very interested in your project, "iOS & Android Productivity App" I have over 12 years of experience and a background in developing projects in mobile application technologies like react native(Android & iOS).

@KarthikTechCon

Hi, I’m Karthik, a mobile app engineer with 10+ years of experience building fast, reliable productivity and task-management apps for iOS and Android. Your focus on speed, clarity, and native-quality UX over feature bloat is exactly how a great productivity app should be built. I’ll keep the core flow frictionless: create → prioritize → get reminded → complete. Proposed approach: • Clean task creation with priority, due date, and drag-and-drop reordering • Local-first data storage with secure cloud sync, so tasks work fully offline • Reliable local + remote push notifications for due dates and reminders • Polished UI aligned with Apple HIG and Material Design standards • Scalable architecture so notes and calendar features can be added later without rework Tech stack (recommended): • Flutter for iOS & Android with near-native performance • Local persistence (SQLite/Hive) + secure cloud sync (Firebase) • Firebase Cloud Messaging for push notifications • Clean state management and modular codebase (If you prefer fully native, I can also deliver SwiftUI + Jetpack Compose.) Timeline: • Week 1: UX flow, data model, core task CRUD • Week 2: Notifications, offline sync, drag-and-drop, UI polish • Week 3: QA, performance tuning, TestFlight & Play Console builds Deliverables: ✔ iOS TestFlight build ✔ Android Play Console build ✔ Complete source code in a private repo ✔ Deployment & handover notes Best regards, Karthik

@uniqedeveloper

Hi, I’ve built several lightweight task and habit apps focused on speed and clarity, including a cross-platform to-do app with offline sync and push reminders used daily by a distributed team. This project is refreshingly well-scoped and aligns with how I like to work: simple core, polished execution. I’d propose Flutter or native SwiftUI + Compose depending on your preference. Data would be stored locally first (SQLite/Room/CoreData) with background sync to a secure backend (Firebase or Supabase). Push notifications handled cleanly with due-date scheduling, and drag-and-drop priority ordering implemented natively for smooth UX. UI will strictly follow HIG and Material standards—no clutter, no lag. I’ll deliver TestFlight and Play Console builds with a clean, documented repo. Questions: Single list or multiple task lists in v1? Any need for recurring tasks at launch? Preferred auth method (email, Apple/Google, or anonymous)? Should reminders work fully offline? Any branding or UI references to follow? Let's get in touch Thanks

@LiamKJ

NO SATISFACTION, NO PAYMENT. Missing the mark on the core task flow risks frustrating users and undermining daily productivity—delivering a sluggish or unintuitive app would jeopardize adoption and long-term retention. Your vision demands more than technical know-how; it requires a deep understanding of user behavior and streamlined workflows. Our approach is focused on crafting a responsive, native-feeling experience that aligns perfectly with platform conventions, ensuring seamless task creation, prioritization, notifications, and offline access without unnecessary complexity. We’ve completed similar projects for clients outside this platform, and to strategically build our reputation here, we’re offering a limited discounted rate that reflects our commitment rather than inexperience. If you’re open to a brief discussion or have specific preferences on platform choices and timeline, I’d welcome your quick reply. Warm regards Liam Jasson

@coretus

Hi there, I’ve been looking at your requirements for a clean, performance-first productivity app and I completely agree that speed and intuition should take priority over feature bloat. I can help you build this from the ground up so that it feels natively responsive on both platforms. For a project like this, I recommend using Flutter. It’s perfect for creating a high-end UI that aligns with both Apple’s Human Interface Guidelines and Material Design while allowing us to maintain a single, high-performance codebase. I can deliver the initial builds for TestFlight and Google Play within 4-6 weeks. This includes setting up the secure cross-device sync and the drag-and-drop priority features you mentioned. My focus will be on ensuring the interactions are buttery smooth so that adding a task feels effortless. Once we pass review, I’ll hand over the full source code and documentation so you have total ownership of the roadmap moving forward. Best regards, Anil
