Wrap Web App into Mobile Apps

Posted yesterday

Worldwide

Summary

We run Crazylive Smart Money (crazylivekalshi.xyz), a subscription-based data analytics platform that tracks the most profitable "smart money" wallets on Polymarket in real time — leaderboards, live trade signals, and market consensus. The product is live, revenue-generating (Stripe subscriptions at US$29/month), and fully localized in Traditional Chinese, Simplified Chinese, and English. We now want to launch it as native mobile apps on the Apple App Store and Google Play. Your mission is to wrap the existing website into store-ready apps and drive both submissions through to approval. Scope of Work: 1. Build an app wrapper for our existing web app using Capacitor (preferred) or a comparable proven WebView-shell approach for both iOS and Android 2. Implement the native essentials reviewers expect: splash screen, app icons (all required sizes — brand assets provided), safe-area handling, deep links, external-link handling, offline/error screen, and pull-to-refresh 3. Integrate push notifications (FCM for Android, APNs for iOS) wired to our existing notification flow 4. Add enough native value to satisfy Apple's Guideline 4.2 (minimum functionality) — we will discuss options such as native push, widgets, or biometric quick-unlock before you start 5. Prepare all store materials: screenshots for required device sizes, app descriptions (we provide copy in EN/ZH), privacy policy URL (already live), data-safety and privacy questionnaires 6. Submit to both stores under our developer accounts (we provide access via Upwork-safe credential sharing or App Store Connect / Play Console user invitations — never ask us for passwords outside these channels) 7. Handle all review feedback and rejections until both apps are approved and live (this is part of the fixed scope, not an extra) 8. Deliver the complete source code repository with a README documenting how to build, sign, and release updates Important — How We Work (Please Read Before Applying): • All project communication is handled by our headquarters AI system on behalf of the company. Communication is via email and Upwork messages ONLY — strictly asynchronous, in written English. • No phone calls, no video calls, no live meetings — please do not request them. Every requirement, asset, and piece of feedback will be delivered to you in clear written form, typically within 24 hours. • This works to your advantage: requirements arrive as precise written specs you can reference anytime, and you work on your own schedule across any timezone. • If written-only, async collaboration does not suit your working style, please do not apply. Requirements: • 3+ years of mobile development experience; at least 3 apps you personally shipped to BOTH the App Store and Google Play (provide store links — this is mandatory and will be verified) • Hands-on experience with Capacitor or Cordova/WebView-shell apps that passed Apple review, including experience overcoming Guideline 4.2 rejections • Experience with push notification setup (APNs certificates/keys, FCM configuration) • Familiarity with App Store Connect and Google Play Console submission workflows, including privacy/data-safety forms • Strong written English and disciplined async communication habits (clear status updates at least twice per week) • Note: the app content is a financial data analytics tool (no gambling functionality, no in-app trading). Experience shipping finance/crypto-adjacent apps through Apple review is a strong plus. Milestones & Payment (Fixed-Price): Milestone Deliverable Payment M1 Working iOS + Android builds (TestFlight / internal testing track) with splash, icons, push 40% M2 Store submissions completed with all materials 30% M3 Both apps approved and live + source code handover 30% To Apply, Please Include: 1. Links to at least 3 apps you shipped on both stores (App Store + Google Play) 2. One example of an app you got through an Apple 4.2 (minimum functionality) rejection, and how you solved it 3. Your fixed-price quote broken down by the three milestones above 4. Your estimated timeline from kickoff to store approval 5. Confirmation that you accept written/async communication only (email & Upwork messages) We respond to all shortlisted applicants within 24 hours — in writing, of course.
