I’m building a mobile learning environment where students can sit for structured test series and access supporting study material. The app must run natively on both Android and iOS, with the entire user journey centred on clear, intuitive navigation and smooth performance. Core testing flow • Two distinct test modes: – Practice Mode: students may retake a paper unlimited times and view instant scoring. – Live Mode: a scheduled exam that opens simultaneously for every registered student and can be taken only once. When the countdown reaches zero, the test locks automatically. Study-material delivery At launch I will share PDFs only, so the admin area needs a quick upload tool and an in-app PDF reader. (The structure should be flexible enough to add vid...

I want to launch a modern, minimalist mobile app on both iOS and Android that lets me sell and manage test-series for students while also sharing study material such as PDFs. The core flow is straightforward: learners sign up with phone-number + OTP, pick a test, and start practicing. Two distinct test modes are essential. • Practice Mode – students can retake these tests as many times as they like. • Live Mode – the paper opens for everyone at the same scheduled time and each student gets only one attempt. Each account must work on a maximum of two devices to discourage sharing. The overall interface should look premium, load fast, and remain completely glitch-free. After the first release I will need ongoing support for updates, bug fixes, and minor feature re...

I need a single code-base application that lets companies who move oversize loads find and book escort drivers quickly. The priority is a smooth, real-time chat that connects the load owner with available escorts the moment a request is posted. The conversation thread should stay synced across iOS, Android, and a responsive web portal, so whichever device people pick up, the same history, files, and read receipts appear instantly. Alongside chat, a lightweight map is required. It only has to display origin, destination, and the suggested route; live traffic layers or GPS tracking can wait for a later phase. Think of it as a visual aid inside the chat window that both sides can reference while they negotiate. Key screens I expect: • Escort marketplace where drivers list their availa...

I need a mobile application built specifically for an e-commerce business. The core of the project is a clean, fast product catalog that lets shoppers browse by category, search items quickly, and view detailed photos and descriptions. From there, the user should be able to add items to a streamlined shopping cart and update quantities or variations without friction. For now, I am concentrating on those two pillars—catalog and cart—while payment processing will be handled separately at a later stage, so no gateway work is required in this phase. Please structure the code so that a payment module can be plugged in later without major refactoring.

My app already runs smoothly on both iOS and Android, but the external services it relies on still need to be wired up. I want every major integration—payments, social, and messaging—implemented end-to-end so users enjoy a seamless experience without ever leaving the app. Payment gateway I have not locked myself into a single provider, so feel free to recommend the best fit (PayPal, Stripe, Square, or another PCI-compliant option).

I need a fast turnaround on a set of up to ten lightweight Unity games for mobile. We will begin with one title and, once that is signed off, roll straight into the remaining nine. Reference: The core puzzle-solving mechanic stays, but everything the player sees or hears must feel brand-new. Think bright, cartoonish characters, playful animations, and a smoother overall flow. I will supply mood-boards and specific animation references so you can focus on execution rather than guessing the style.

I’m ready to turn a new app concept into a polished product and I’m looking for a developer who can guide the whole build— from setting up the architecture to publishing in the stores. The core brief is straightforward: • The app’s topic is still open; I’ll share final wireframes and user stories once we connect. • Three headline features will drive the first release. I have rough notes that currently map to standard staples such as secure sign-in, real-time alerts, and optional monetisation hooks, but I’m happy to refine these together so they fit the chosen tech stack and platform guidelines. • I haven’t locked myself to iOS, Android, or a cross-platform solution yet.

The response must open with a friendly greeting, list my contact details, and then show a clear order menu with concise instructions on how to place an order.

Here’s what I expect from you: • Craft the copy (including emojis or line breaks where they improve readability) so it fits comfortably within WhatsApp’s character limits and looks clean on both Android and iOS. • Format the order menu so customers can see numbered or bulleted options and understand the next step at a glance. • Activate the auto-reply inside my WhatsApp Business settings...

I’m ready to commission a cross-platform mobile app that streamlines every aspect of my security company’s field operations.

I’m building a mobile application that must perform and feel identical on Android and iOS—I value both equally, so each platform needs the same polish, speed, and attention to detail. My preferred stack is React Native for the shared frontend layer; if you are comfortable weaving native modules or platform-specific tweaks into that workflow, even better. The scope covers everything from setting up the project repository through to releasing a production-ready build on Google Play and the App Store. Along the way I’ll need clean, well-commented code, component-level testing, and logical Git commits so future iterations remain straightforward. Deliverables • React Native codebase configured for Android and iOS • Integration of any native modules we identify as...

I need a native Android application whose sole purpose is to help users work smarter and stay organised. The app will be positioned squarely as a productivity tool, so every screen, interaction and workflow should reinforce speed, clarity and ease of use on mobile.

Clean Material-design styling, smooth performance on recent Android versions and sensible local data storage are non-negotiable. If you can architect the project so that future integrations—such as Google Workspace or Microsoft Office—can be a...
