All that remains is the actual submission to App Store Connect and shepherding it through Apple’s review until it appears in the store. Here’s the flow I expect: • Generate the production build with the correct signing certificates and provisioning profiles already sitting in my account. • Set up the App Store Connect record: pricing, territories, app privacy details, compliance questions (no in-app purchases). • Upload the build via Transporter or Xcode, spin up a quick TestFlight group so I can run a last internal test, then move it into “Ready fo...

I have a fully-functioning e-commerce web application and an Apple Developer account that is already active and verified. What I now need is a specialist who can turn that site into a compliant iOS submission and push it live on the App Store. You will be responsible for: • Wrapping the web app in an Xcode project (WKWebView or an approach you know will pass review). • Creating all required certificates, identifiers, and provisioning profiles. • Configuring the App Store Connect record, including metadata, categories, age rating, and any required privacy details. • Uploading the build through Transporter/Xcode and guiding it through App Review until it is approved and listed.

Annual Maintenance Contract • Proactive monitoring, quick bug fixing, security patching and version updates • Monthly health reports and a clear escalation path for any critical issues • Store-listing support whenever OS or policy changes demand it 2.

I’m opening a small closed test for my new Android mobile app and need exactly 12 people to take part. All I need from each tester is a valid email address so I can send the Play Store invite. Once you accept the invite, you’ll install the app, use it as you normally would for the next 14 days, and share any issues or thoughts you spot along the way. Key details • Platform: Android only • Test type: Closed Testing (no public sharing, please) • Payment: a single total of $2 will be released to cover all 12 testers after the full 14-day period is complete. Deliverables (per tester) 1. Email address for the invite 2. Proof of installation (screenshot) 3. At least one short feedback message during the 14-day window 4. Final confirmation that the app r...
I need an Android APK that focuses on one clear flow: letting new or existing customers complete a payday-loan application quickly and securely. Core flow • Users land on an OTP screen, enter their phone number, and receive a one-time code to unlock the app. • After successful verification, they reach a single multi-step form that gathers their personal information (name and address), employment details, and bank information. • When the final step is submitted, the data should be stored safely in a backend or Firebase collection I can later review. Interface & tech notes • A lightweight, modern UI in Kotlin or Flutter is fine—choose whichever you work fastest in. • Keep the code organised so I can hand it to another developer later for interes...

I need a skilled Android developer to build a dedicated e-commerce application from the ground up. The core goal is to give users a smooth shopping experience on Android phones and tablets, so performance and intuitive UI patterns matter as much as clean code. Here are the essentials I must see in the first release: • Product catalog that lets shoppers browse, filter, and view detailed item pages • Shopping cart that updates in real time and persists between sessions • Secure payment-gateway integration (I’m open to Stripe, PayPal, or any PCI-compliant option you recommend) Everything should be written natively for Android—Kotlin is my preferred language, though Java is acceptable if it speeds up delivery. I will provide branding assets and product data ...

I need a clear, actionable strategy for push notifications in my fashion shopping app. The focus is on NEW ARRIVALS alerts that fire the moment a user browses a specific category—no delays, the message must go out immediately. Here’s the flow I want mapped out: • Identify the in-app event when a customer lands on or scrolls through a category page. • Capture the event and trigger a personalised “New Arrivals” notification in real time. • Outline the copy style, ideal character count, imagery guidelines and suggested deep-link destinations so the alert feels helpful, not spammy. • Recommend the technical setup (e.g., Firebase Cloud Messaging, OneSignal, or another SDK you trust) including segmentation tips, rate-limiting safeguards, and an...
I need a native-or-resident Indonesian Android user to help me confirm and, if approved, purchase a few in-game items from a Gacha title on Google Play. Here’s how the collaboration will work: 1. You install the specified game (I’ll give you the exact link). 2. You open its in-app store, capture clear screenshots of every relevant bundle so I can see the Indonesian rupiah pricing. 3. Once I green-light the deal, after inspecting the prices, you will be awarded the amount we agree you can do purchas on 4. You send me the Google receipt and a final screenshot showing the items credited to the account. To keep everything smooth, please ensure your device is Android (the game is not on iOS) and that Google Play billing for Indonesia is active. Fast turnaround and accura...

I’m building an iOS application where every screen, control and workflow adapts to three distinct personas: ModuleUser, ModuleAdmin and OrgAdmin. The core requirement is that the same binary ships to the App Store, yet the active Navigation menu, Dashboard, Analytics views and other modules switch on or off through feature flags. Here’s what I need from you: • A clean Swift / SwiftUI codebase that checks a user’s persona at launch and renders the corresponding UI variant. • A feature-flag framework (LaunchDarkly, Firebase Remote Config or a lightweight in-house solution—your recommendation is welcome) to toggle those variants without a fresh release. • Role-based access control so that actions available to ModuleUser, ModuleAdmin and OrgAdmin...
Our live roadside-assistance suite—one consumer app and one tow-driver app, now topping 40 k installs—needs an experienced React Native engineer to squash the remaining Android-side bugs. Current pain points to resolve: • Driver registration occasionally throws false error messages. • Admin panel (cPanel) cannot reliably create, edit, or delete driver accounts in the database. • Call-matching logic sometimes fails to assign the nearest available driver. • A handful of driver account-setting screens are not saving changes properly. I have staging keys, Play Console access, and a transparent Git history ready for you. Once these fixes are confirmed in production, the role will expand into ongoing ownership of the codebase, including an AI-powered...
Devo dare vita a due applicazioni native, una per iOS e una per Android, con finalità distinte ma codice e logiche condivise dove possibile. • Per Android mi occorre una vera e propria app di produttività: gestione attività, promemoria intelligenti e sincronizzazione cloud dovranno essere il cuore del progetto.
 • Su iOS, invece, voglio puntare sull’intrattenimento: contenuti multimediali fruibili in streaming, piccole funzioni social (like/comment) e un’interfaccia che rispetti le linee guida Apple in termini di animazioni e gesture. Mi aspetto: – UI/UX completa (Figma o simili) con prototipi cliccabili;
 – sviluppo in un framework cross-platform moderno (Flutter, React Native o simili) o in nativo qualora garantisca prestazioni mig...
