I’m new to this platform and need a clear, step-by-step walkthrough of the bidding process inside both the website and the mobile app. My main goal is to become confident at writing proposals that actually win work, with a special focus on how to highlight my skills and experience so they speak directly to a client’s needs. Here’s what I’d like from you: • A live screen-share session (or two, if needed) where you show me exactly where to click, what to fill in, and how to submit a bid from start to finish. • Practical guidance on structuring the proposal text, but drilling deepest into the “skills & experience” section—how to choose the right achievements, quantify results, and keep it concise. • At least one reviewed ex...
I’ve come up with an idea for an app I’ve put it below please feel free to run with it if you want to. I just don’t know or have the time to do anything with it. Or know where to start. EARNED – Discipline Before Dopamine EARNED is a behavioural technology platform designed to tackle one of the largest modern challenges: uncontrolled digital consumption. Today’s social media platforms spend billions of dollars engineering products that maximise attention. EARNED reverses that model by creating a system where screen time is earned through positive action rather than consumed passively. The platform uses Apple’s Screen Time framework and on-device artificial intelligence to restrict access to selected apps until users complete real-world tasks such as...

I’m launching a green-field application that must run seamlessly in the browser and as a native Android build. Your job is to take it from concept to deployment, delivering a slick, modern interface backed by a robust database and a secure email-and-password sign-in flow.

I need a full-stack Flutter developer to turn my concept for a habitat-condition data collection system into a production-ready product. Mobile app • Built with Flutter for Android and iOS • Works fully offline, including photo capture, GPS tagging and entry of vegetation cover, soil health, water quality, field notes and any other custom fields I configure • Stores records locally and auto-syncs to a secure cloud MySQL database the moment connectivity returns (no data loss permitted) Admin & analytics web console • Role-based access: researchers / ecologists will need dashboard privileges alongside standard survey managers and system admins • Create and edit survey templates on the fly, activate / retire them and manage user accounts • Leafl...
I want to turn my website into a sleek, cross-platform mobile experience that draws users back every day. The core goal is user engagement, so the app must feel instantly familiar yet noticeably smoother than the current mobile web version. A clean, minimalistic look is essential—simple typography, plenty of white space and subtle motion that highlights, rather than distracts from, the tools on each page. Key functionality I need from day one is native push notifications. They should be easy for me to schedule and segment so I can nudge specific user groups whenever new content or tools go live. Smooth onboarding, intuitive bottom-tab navigation and lightning-fast transitions between screens are equally important, but notifications are the single must-have engagement feature. I wi...

I’m rolling out Moego and need the whole sales-to-appointment flow tuned so customers can discover services, buy on the spot, and lock in a time without friction. That means configuring every selling feature Moego offers while also activating its appointment-booking module so both pieces work in tandem. The system has to fire perfectly on my website and in the companion mobile app. I’ll supply the brand assets, service menu, pricing tiers, and current site/app access; you make Moego do the heavy lifting—product catalog, add-ons, payment gateways, calendar rules, confirmations, reminders, and follow-ups. Deliverables: • Complete Moego sales setup connected to my service list • Appointment booking workflow tested end-to-end • Seamless integration on w...
I’m getting ready to publish a new utility app and need 20 committed Android users to put it through its paces in a private Google Play Console track for two full weeks. During the 14-day window you’ll install the build, use it naturally each day, and send me clear feedback focused on: • The overall user interface and experience—anything confusing, awkward, or visually off share a simple bug-report template and a brief survey that you’ll complete every other day. Screenshots or screen recordings are encouraged whenever you hit a problem or spot something that feels wrong. Deliverable at the end of the test: one concise summary document listing all issues you found, steps to reproduce them, and your top five improvement suggestions. Once I confirm the r...
I want an Android app that lets my tuition-class students handle everything in one place. First, they must be able to create an account or log in with existing credentials. Once inside, the timetable should load automatically and push a notification whenever I add, cancel, or reschedule a session. A built-in messaging area is essential so students can reach me (and I can reach them) without shifting to another platform. I’m intentionally leaving out payments and other extras for now; the focus is on registration, schedule visibility, real-time alerts, and smooth in-app chat. Deliverables I expect: • A production-ready Android APK and its full, well-commented source code (Java or Kotlin, latest stable SDK). • Simple admin access or clear written steps that let me u...
I already have a fully-functional mobile app connected to a Bubble back-end and currently distributed through TestFlight. What I now need is a complete visual and experience refresh using the brand-new Loveable designs I’ve received. The job is straightforward: swap out the current interface and flows so that the app looks and feels exactly like the Loveable concept. Because I want both the UI and overall UX updated, you’ll be touching every live screen that users interact with, wiring those refreshed layouts back to the same Bubble endpoints and logic that power the app today. Deliverables • All screens rebuilt to match the Loveable mock-ups pixel-perfectly (colour, typography, spacing, animations, etc.). or can I paste project to bubble? • Updated navigati...
I need an intuitive expense-management app designed for everyday individuals and released simultaneously on iOS and Android. The core goal is to let users record purchases quickly, view their spending habits at a glance and stay on top of monthly budgets without the complexity that usually comes with finance apps. Key expectations • Smooth onboarding with email, Apple, Google or phone sign-in. • Rapid transaction entry: manual input, recurring payments and photo receipt capture. • Smart categorisation (food, travel, bills, etc.) that the user can edit or merge. • Clear visual summaries: daily and monthly totals, category pie charts and line-graph trends. • Budget alerts that notify users before they overspend. • Secure cloud sync so data stays consi...
I need a dedicated Android application that lets customers browse products, add them to a cart, and check out securely—all in a smooth, modern interface. The project is strictly mobile app development for the Android platform, and the end goal is a fully functional e-commerce experience that I can publish to Google Play. To succeed you will design the UI, code the app, connect it to a back-end (I’m open to your recommended stack), and make sure payments, user accounts, and product data flow reliably. Core deliverables: • Release-ready APK and complete source code • Material-styled UI that adapts to phones and tablets • Integration with a payment gateway and a simple product database or API • Clear documentation so I can maintain or extend the a...
I’m ready to take 360kart Pro from “almost there” to a fully polished shopping experience and need a capable developer to jump in alongside our CTO, Prince. What we must tackle first is the user interface. The navigation menu, product display pages and the entire checkout flow need a cleaner, more intuitive look and feel while keeping the existing brand guidelines intact. Smooth transitions, consistent spacing and responsive layouts across devices are essential. Equally important is performance. Users are currently facing slow loading times, occasional crashes and a general lag during browsing. I need you to profile the code, squash the crash triggers and implement proven optimisation techniques so the app feels snappy on even modest hardware. Finally, a handful of p...
Hi I will share the details with the shortlisted candidates. Thanks
1. Overview This project covers the design and delivery of an all-in-one car rental and fleet management system: a single system that handles reservations, fleet, payments, customer communication, and reporting for a rental operation. The goal is to replace the usual patchwork of spreadsheets, paper agreements, and disconnected booking tools with one connected workflow that runs from a customer's first booking through to the final invoice. The platform is built for car and van rental as its core use case but is structured to flex into adjacent rental markets — motorbikes, boats, equipment, and long-term leasing — through configuration rather than rebuild. ## 2. Objectives - Let customers book and pay 24/7 through a branded online channel, without a phone call or a deve...

I’m trying to submit my very first proposal from the Freelancer mobile app, but the “Place a Bid” button never shows up on my phone. I suspect it’s tied to account-level permissions rather than a simple navigation problem, so I need targeted, step-by-step help to unlock or activate whatever setting is preventing the button from appearing. Here’s what I expect from you: • Quickly diagnose the permission or profile requirement that blocks the bid feature. • Walk me through the exact path on the Android / iOS app (and, if necessary, the web dashboard) to enable bidding. • Stay on the call or chat until we confirm the button is visible and I can actually submit my first bid. If additional verification steps, identity checks, or profile edits...

I’m building a new social-networking application that will launch simultaneously on iOS and Android. The initial release focuses on robust User Profiles: sign-up and sign-in (email, phone or social OAuth), avatar upload, editable bio, and basic privacy settings. Messaging and a news feed may arrive in later phases, so please structure the code so those modules can snap in without refactoring the core. Clean UI/UX, smooth native performance, and adherence to both Apple and Google store guidelines are critical. I will supply wireframes, brand colours, and a feature specification once we agree on the approach. You’re free to recommend native (Swift + Kotlin) or a cross-platform stack such as React Native or Flutter—whichever delivers the best user experience and maintainabi...
I’m planning an Android app designed to make everyday life a little easier by connecting ordinary people with a supportive community. The core idea is simple: users open the app, find others facing similar challenges, share advice in real time, and access curated help resources. Here’s what I need from you: end-to-end Android development—from refining the concept and mapping the user journey, through clean, well-documented Kotlin or Java code, all the way to a polished, Play-Store-ready build. Reliability is crucial; regular progress updates and tested, maintainable code matter as much to me as the final feature set. Because community and support sit at the heart of the product, experience with chat systems, push notifications, secure user authentication, and scalab...
I want to build a specialized options screener that filters contracts in real-time based on two main criteria: raw price and volume data. My goal is to display only those strikes that meet dynamic thresholds—which I can adjust as needed. The back-end logic is the priority. I need reliable data ingestion (API or direct feed), a rules engine where I can add or modify filters without altering the core code, and an interface that clearly displays the resulting option chains. I am flexible regarding the front-end stack and deployment target; whether it’s a mobile-friendly view or something else, just suggest an approach that allows for rapid development and easy maintenance. Deliverables • Clean, well-commented source code for the screener • A configuration file or panel...

I am building a full-stack solution that lets customers order everyday essentials at discounted prices from their phones. The project has three main parts: • Customer apps – A single codebase compiled for Android and iOS. Shoppers must be able to create an account with email, phone number, or any of their social media logins, browse the catalogue, place orders, and choose either home delivery or pick-up from the address they specify.
