I am looking for a professional app developer/team to review my existing project and give me a realistic price to make it ready for Android and iOS. This is not a simple website project. It is a marketplace-style app called Vixo, where people can request practical everyday help, and local helpers can accept tasks, send bids, chat, share GPS location when on the way, and later receive payment through the platform. The app is currently built as a mobile-first web app and is prepared for Capacitor. The goal is to make it ready for Google Play and Apple App Store. I do not want rushed work or quick promises. I need a serious developer who can inspect the current project, understand the purpose, and give a clear price and plan. Main app concept: - Users can request help with everyday practical tasks - Helpers can create profiles and services - Customers can create tasks - Helpers can bid on tasks - Customers can accept a helper - Chat must work between customer and helper - GPS/live location must work when the helper is on the way - Notifications must work properly - Admin panel must allow support, task overview, users, helpers, reports and price/fee overview - Payment system must be prepared so the platform can later take a fee/commission Important features that must work: - Android app - iOS app - Capacitor setup - Push notifications - GPS/location tracking - Chat - User roles: customer, helper, admin - Helper profiles with rating/reviews - Open bidding system - Price agreement system - Admin panel - Future payment/fee system - App Store and Google Play preparation Payment system: In the first version the platform is free for testing, but the app must store agreed prices, task value, helper payout and future platform fee. Later all payments should go through the app, and the platform should be able to take a commission/fee. I need a developer who understands marketplace apps, not just basic websites. Before I choose anyone, I want to see: 1. Apps you have built before 2. App Store / Google Play links if available 3. Experience with GPS/location tracking 4. Experience with push notifications 5. Experience with payment systems, preferably Stripe Connect or marketplace payments 6. Experience with React / Capacitor / Supabase or similar stack 7. Your suggested plan 8. Your estimated fixed price or milestone price Please do not send a generic message. Start your reply by explaining how you would approach: - reviewing the existing project - making it ready for Android/iOS - implementing push notifications - implementing GPS - preparing the payment/fee system - getting the app ready for App Store and Google Play I will not make a rushed decision. I need someone professional, honest and experienced.

Hi Anders — this bid reflects what we agreed after I reviewed the full Vixo codebase (frontend, Supabase schema, RLS, Capacitor setup). Complete package to get Vixo live on both Google Play and the App Store: $2,900 total, fixed price, split into clear milestones you approve and pay one at a time — no big upfront. We start with M1 + M2 (security verification + native shell and real device builds), then push notifications, native GPS, and store submission. Stripe (test mode + live activation) sits at the end for whenever you're ready to take payments — Vixo ships as a payment-free MVP first. Everything runs through a cloud build pipeline + TestFlight, and I handle the first technical review round if Apple or Google flag anything. Milestone breakdown below.

Hi, A marketplace app like Vixo usually breaks at key handoff points: task creation, bidding, chat, live location, and payment/commission logic. The best first step is a full review of the current Capacitor build to identify what is already solid, what still belongs to the web layer, and what needs native app work before store submission. I’d start by auditing the existing codebase, data flow, and Android/iOS readiness, then map the work required for push notifications, GPS tracking, chat reliability, and admin/support flows. On the payment side, I’d review how prices, payouts, and future fee handling should be structured now so commission payments can be added later without a rewrite. Key focus: - Review current project structure - Check Capacitor and native app readiness - Audit push notifications and location flow - Review chat and role logic - Plan payment/fee data model One quick question: is the backend already handling task, chat, and location data, or is that still partly in the mobile web app? I can review this with you via Freelancer chat or video call, 11 AM–8 PM IST. If helpful, please share the current build and I’ll outline the next steps.

Interesting project, Vixo is exactly the kind of marketplace app I focus on: task bidding, real-time chat, GPS tracking for helpers en route, and push notifications across both platforms. I will review your current Capacitor setup and codebase first, then give you a clear milestone plan covering Android/iOS readiness, native push notifications, live location sharing, and the payment structure (storing task value, helper payout, and future platform fee so Stripe Connect slots in cleanly later). On a similar marketplace build, setting up Capacitor plugins for GPS and push early in the review phase saved weeks of rework, because those two features expose most of the gaps between a web app and a native-ready one. I will do the same here. Questions: 1) Is the current stack React with Supabase, or something different? Ready to start whenever you are. Kamran

Hi, reviewing and upgrading an existing app like Vixo is usually less about adding features and more about finding where the current architecture is brittle before changes compound it. The real engineering risk is hidden coupling between mobile flows, backend state, and release behavior, especially if the current app has drifted without a clean audit path. I’ve worked on live product upgrades where the first step was a code walkthrough, issue isolation, and defining the safest path to improve functionality without destabilizing production. With Vixo, I’d want to understand whether the pain is in the app layer, API behavior, or data sync around Supabase. The closest match here is Custom Feature Development & Integration, where I reviewed an existing codebase, identified friction points, implemented improvements, and added test coverage for stability. I usually structure this kind of work in phases: audit current flows, isolate failure points, then separate quick fixes from architectural corrections. That avoids patching symptoms while leaving the underlying state model unresolved. I build systems for long-term maintainability, not one-off edits that create more regressions later. If useful, I can start by sketching a concise upgrade audit: current app flow, risk areas, and the highest-value fixes first. Thanks, Hercules

Hi there, I can help you review and upgrade the Vixo app. I've built marketplace apps before and understand the full scope. My approach would be: first inspect the current codebase and Capacitor setup to identify gaps, then tackle each feature area methodically push notifications using Firebase Cloud Messaging, GPS tracking via Capacitor Geolocation plugin, chat with Supabase realtime, and Stripe Connect for the payment/fee system. For iOS/Android readiness, I'd handle provisioning profiles, app signing, and store metadata. I'm Edward and I've shipped similar apps to both stores. Let me know if you want to discuss specifics.

Hey, keeping GPS tracking active in Capacitor when a helper locks their phone is where most marketplace apps stumble. I'll audit your codebase first, focusing on background geolocation plugins and OS permissions. That's tricky because Apple's strict background execution rules often reject apps tracking location without a clear user benefit. Is your current web app built on React or Vue, and do you have developer accounts set up?

Hi, I’ll review Vixo by mapping the Capacitor web-first flows to native app expectations, focusing on GPS, chat, and bidding to ensure Android and iOS share core logic with native polish. Relevant experience signal: I’ve led marketplace upgrades with mobile-first stacks and payments scaffolding. Execution approach: I’d validate the current flow, isolate unstable parts (push, location, admin tooling), and quick-sprint a plan aligned with Agile Development and iPhone-focused Mobile App Testing. One technical risk: iOS GPS live tracking during navigation may need careful battery and permission handling. Two clarification questions: What is your rollout strategy for Android and iOS, and should we use a shared Capacitor codebase or native wrappers for location and chat? How should payments be staged in v1, free testing with stored prices and later commissions, and what are your Stripe Connect readiness priorities? If we're aligned, I can outline the implementation phases before kickoff. Best regards, Brandon

To review your Vixo app, I would first do a detailed code audit focusing on existing Capacitor integration, key features like chat, GPS, and notifications. This helps identify gaps for native readiness and app store rules. For Android/iOS readiness, I’d optimize the Capacitor setup, verify plugin compatibility, and test all device APIs (camera, GPS, notifications) thoroughly on real devices to ensure smooth performance and compliance. Push notifications work best via FCM on Android and APNS on iOS. I’d integrate these through Capacitor plugins, ensuring background notification handling and in-app updates without missing messages. GPS location tracking would run continuously with permission management, updating live location only when the helper is on the way. I’d implement efficient background tracking to save battery but keep accuracy, tested across common devices. For payment preparation, I’d set up secure price storage and task value tracking, planning for Stripe Connect integration to handle payouts and platform fees later. This keeps the first version free but ready for seamless upgrade. Publishing involves app store guideline checks, preparing metadata, privacy policies, and testing compliance on both platforms, ensuring smooth review and approval. Could you share access to your current repo or a demo? Also, are you using any backend for real-time chat and notifications now? I’ve helped marketplace apps navigate similar transitions, and I’m ready to provide a clear fixed milestone plan once I review your code. Let’s get this app fully ready for launch.
