Five-Screen HarmonyOS Utility App

@KESHAVINFOTECH

Hi There, 1.I need a lightweight utility application built exclusively for HarmonyOS.... ==> We got your requirements for the HarmonyOS utility app. We are very comfortable working with ArkUI to create that polished and native experience you want. We will focus on making the notifications and app integration work perfectly. We have built similar utility apps in the past. One of them had a unique feature where it could create profiles that automatically adjusted system settings based on the time of day or location, without needing user input each time. We have reviewed your list of deliverables. We will provide you with the complete and well-documented ArkUI source code, a release-ready HAP package for easy installation, and a simple README file with all the build instructions. We also understand there will be one revision cycle for minor changes, which works for us. ## Queries : 1. Could you please provide more detail on the main purpose of this utility tool and which specific external HarmonyOS app or system module we will need to integrate with for data exchange? ## Initial Project Structure : - Main Dashboard - Integration Settings - Notification Log - User Preferences - About We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

I have hands-on experience building lightweight apps using Huawei’s ArkUI framework and can deliver polished, fully native UI across all five screens. For real-time notifications, I’ll integrate HarmonyOS’s notification service to ensure alerts come through even when the app runs in the background. To handle data exchange, I suggest connecting with the built-in HarmonyOS calendar or contacts app via their APIs, which is a reliable way to demonstrate external app interaction. I will provide clean, well-organized ArkUI source code plus a release-ready HAP package tested thoroughly on HarmonyOS 3+ devices. The README will detail build instructions and necessary Huawei kits or permissions. After delivery, I’ll handle one revision cycle for polish or minor adjustments. Could you confirm if you have a preferred app in mind for integration or should I proceed with calendar/contacts? What timeline do you expect for the initial version? I’m ready to start immediately and keep communication focused on quick, clear updates.

Hey there !! I can deliver a fully native HarmonyOS utility app using ArkUI, optimised for speed, low footprint, and clean system integration. A five-screen scope is ideal for doing things properly—tight navigation, consistent layout, and zero unnecessary abstraction. Approach & stack • ArkUI (Stage model) with declarative UI components • HarmonyOS Notification Kit for real-time background alerts • Ability-based navigation with clear lifecycle handling • Inter-app interaction via HarmonyOS system abilities or supported app-to-app APIs (depending on your target integration) What I’ll deliver Well-structured ArkUI source with clear separation of UI, state, and services Release-ready HAP package, tested on HarmonyOS 3+ phones/tablets Short README covering build steps, required Huawei kits, permissions, and signing One post-handoff revision pass for UI or behaviour tweaks across all screens Quality checks • Cold launch and background resume tested • Notification delivery verified in foreground/background • External app/system interaction demonstrated with a reproducible test case • No console errors or deprecated APIs Once you confirm the target external app/module and notification triggers, I can share a concrete timeline and screen-by-screen plan and move immediately. Warm regards, Safal Bhatia

I can build the 5-screen HarmonyOS app in ArkUI, with real-time notifications via the HarmonyOS notification service and one external app or system-module integration. Success is: HarmonyOS 3+ launch with no errors, all five screens reachable with clean navigation, notifications firing in real time in background, and a repeatable test that shows the external interaction working. First I’ll scaffold the ArkUI project with the full navigation flow and state model, then implement notification publish/subscribe and validate behavior on a HarmonyOS 3+ device or emulator with proper permissions. Which ArkUI stack are you targeting, ArkTS (preferred for HarmonyOS 3+) or JS, and what external interaction do you want: share sheet, calendar, contacts, file picker, or deep link to another HarmonyOS app you already use? Pitfalls: background limits delaying notifications, missing permissions, device-specific behavior, deep link routing issues, and packaging/signing problems for the HAP. I’ve shipped native mobile utilities with system notifications, deep links, and strict performance requirements. Can start today and deliver in 3–5 days with one revision round. Hope to discuss more on chat. Best, Danylo Podolskyi

@Dmitrydev1

Hi there, I’ve reviewed your Five-Screen HarmonyOS Utility App brief and I’m confident I can deliver a polished, fast, fully native ArkUI solution that stays within the five-screen scope while delivering a seamless user experience. With hands-on HarmonyOS ArkUI development, I’ve built lightweight utilities that reliably show real-time notifications via the HarmonyOS notification service (including background delivery) and integrate with external apps or system modules for data exchange. For this project, I will architect five cohesive ArkUI screens with clean navigation, a native feel, and optimized performance. Deliverables include: complete ArkUI source code with inline documentation, a release-ready HAP package installable on HarmonyOS 3+ devices, and a concise README detailing build steps and required Huawei kits/permissions, plus a one-revision cycle after hand-off for minor tweaks. Acceptance criteria will be met: the app launches without errors, all five screens are accessible via intuitive navigation, notifications arrive in real time, and the integration scenario demonstrates data exchange with at least one external HarmonyOS app or system module. Timeline and approach: I can start immediately and deliver a stable prototype within five days, with final polish within the same window. After hand-off, I’ll accommodate one revision cycle for tweaks across screens. Best regards, Dmytro

@mhirforwork

Hi, I can test your HarmonyOS utility app and verify that all five screens work smoothly and meet your acceptance criteria. I will: - Test navigation between all screens - Verify notifications trigger correctly (foreground/background) - Check integration with external HarmonyOS apps - Identify UI/UX issues and functional bugs - Provide clear reproduction steps with screenshots I can start immediately once you share a build or access. Thanks.

@drosashallal

السلام عليكم .. تواصل ويايه وسهله ... I can build your HarmonyOS-only utility app as a clean, fully native ArkUI project (5 polished screens) with fast navigation, real-time notifications, and a demonstrated integration with at least one external HarmonyOS app/system module. I’ll implement HarmonyOS notification service so alerts fire instantly (including background delivery where allowed by permissions), and I’ll add a clear external interaction via Ability/Intent routing or a system kit (e.g., Contacts/Calendar/Files/Share Sheet), depending on the exact data you want to push/pull. Deliverables: well-structured ArkUI source code with comments, a release-ready .hap, and a short README covering build steps, required Huawei kits, permissions, and a test scenario. I also include one revision round for minor UI/flow tweaks. Approach & timeline: setup + UI/5 screens first, then notifications, then external integration + QA and packaging. Share what the 5 screens are and which app/module you want to integrate with, and I’ll confirm a precise timeline and implementation plan.
