We have an Android app (TC58) that prints ShipStation shipping labels (4x6 PDF) to a Zebra mobile printer over Bluetooth. We need a definitive fix for unreliable PDF Direct printing and a robust default path that works across power cycles and app sessions. Current setup Device: Zebra TC58 (Android handheld) Printer: Zebra mobile thermal printer (Link‑OS 6.x) over BLE Labels: ShipStation 4" x 6" PDFs (~63 KB) SDK: Zebra Link‑OS Android SDK (Bluetooth + FileUtil/sendFileContents) What we’ve tried and observed We toggle (PDF Direct) per print: set to pdf before print, none after. This is wrong per Zebra docs; only applies after a printer restart. After the first successful label, subsequent prints often fail silently (no label) or “corrupt” printer state ...

I need a straightforward Android application that lets a user record daily expenses and keep an eye on their spending habits over time. Core workflow is simple: the user adds an expense, assigns one of five fixed categories (Food, Transport, Shopping, Bills, Other), and can later update or remove that record whenever needed. Every entry is stored locally with Room/SQLite so everything works offline. The interface can stick with the default Android UI components; polished visuals are welcome, but I do not require a full-blown Material makeover. What matters is a clean layout, dark-mode support, and snappy navigation between the main screens: • Dashboard – an overview that totals weekly and monthly spend, plus a running balance. • Detail list – searchable and filter...

My browser-based 3D maze () works smoothly on desktop, yet mobile browsers choke. I need an experienced web-game optimiser to: • Diagnose the bottlenecks in the current Web build (likely WebGL asset size, compression, streaming, or shader setup). • Apply best-practice fixes so the game opens quickly and runs fluidly on standard Android and iOS browsers without breaking the existing desktop experience. • Provide a reproducible build process and a brief change log so I can maintain it going forward. Acceptance criteria – Game loads in under 5 seconds on a typical 4G connection using Chrome’s network throttling. – Sustains ~30 fps on a mid-range Android (Pixel 4a class) and iPhone SE. – No new functional regressions on desktop. Deliverables...

I’m planning a new utility-style Android application and want to team up with a developer who can turn the concept into a polished product. The goal is a single code-base that runs smoothly on smartphones, tablets, and popular wearable devices. Scope • Shape the core feature set with me from early wireframes through a functional MVP. • Build clean, maintainable Kotlin/Java code that follows current Android best practices, Material Design, and responsive-layout guidelines. • Handle Play Store preparation—package signing, versioning, and listing assets. • Set up a lightweight CI/CD flow (GitHub Actions or similar) so future iterations ship quickly. • Provide basic analytics hooks and crash reporting for post-launch insight. What I’ll suppl...

Make Our MVP flatshare Marketplace Feel Premium About us We're a pre-launch real-estate/flat-share marketplace. The MVP is built and the backend is fully working and integrated. This is a front-end-only engagement. We want someone with real UI/UX taste to lift the whole product to a premium, polished, launch-ready standard and also perform the code changes. The work Bring our 15-20 core user-facing pages to a consistent, high-end standard — the pages seekers and listers actually use: homepage, search results, listing detail, the "post a listing" wizard, edit listing, listing preview, user profile & account, saved listings, messages, and sign-in/up.

We are Heartland Promotional Products, an established promotional products company serving business clients in Ohio. We are looking for an experienced mobile app developer to build Version 1 of a new client relationship application called Hit-Up Heartland. This is not an e-commerce app. It is not a product catalog. It is not a CRM. It is intentionally simple. Our existing clients often think of a project, question, or promotional idea while they are in meetings, traveling, or working. Instead of expecting them to remember to call later, this app gives them a simple way to notify our team in seconds. The attached PDF contains the complete project specification. Please read it before bidding. ⸻ Version 1 Features * iPhone and Android * Flutter preferred * Customer registration (on...

My Shopify store’s Inbox chat icon is fully functional on desktop, yet on any mobile device it looks clickable but never opens. Shopify Support hinted at a clash with either a third-party app or the heavy custom code inside my theme. What I need from you I want the real root cause isolated and eliminated—not a quick patch. While my own suspicion leans toward a CSS conflict (pointer-events, z-index, hidden overlays, etc.), the investigation should also cover JavaScript event listeners, App Embeds, and possible collisions with Avada apps or other installed plugins. How you will work • Safari Inspector is my preferred live-device debugger, though you’re free to confirm findings in Chrome DevTools or any tool that yields solid evidence. • You’ll step...

I’m looking for a skilled Android developer to transform my concept, “1000askia,” into a fully functional mobile app. The first release focuses on a clean, stable build with in-app purchases implemented through Google Play Billing. Here’s what I need: • A native Android application written in Kotlin or Java, compatible with the current Android SDK. • Seamless in-app purchase flow (subscriptions or one-time unlocks, depending on what you recommend for best user experience). • A lightweight dashboard or admin configuration so I can add or adjust purchasable content without digging into code. • Polished UI that matches material design guidelines; wireframes or a quick prototype are available on request. • Source code, build instruc...

I need a straightforward way to silence every caller and texter on my iPhone except one specific contact whenever I’m in a meeting. Calls and texts from that chosen person (my wife) must still ring through; everyone else should be muted until I turn the filter off. Here’s what matters: • It must cover both calls and texts, not just one or the other. • I’m fine with either a clever use of built-in Focus / Do Not Disturb settings, a Shortcut, or a third-party app—whichever reliably delivers the result. • Extra conveniences such as quick on/off toggles, schedule presets, or small automations are welcome if they make the workflow smoother, but the core requirement is the selective blocking itself. Deliverable 1. A clear, repeatable setup (writte...

I’m assembling a real-time dashboard solution that must run smoothly on both web browsers and mobile devices. The front end will be built with modern HTML, CSS and vanilla JavaScript where appropriate, but React will drive the component logic and state management. On the back end I already have a FastAPI service in place; your task is to consume those endpoints, handle authentication with Firebase, and persist light local data through SQLite when the connection drops. The application needs to feel product-ready from day one: fast initial load, fluid charts that update live as new data streams in, and a UI that scales cleanly as we add new metrics. Efficiency and long-term maintainability matter more to me than quick hacks, so clear component structure and thoughtful API integratio...

The project revolves around building an educational Android application that acts as a “Personal Teacher” for users who want to learn Android-app concepts step by step. Think bite-sized lessons, short challenges, and quick feedback loops that make the phone feel like a private tutor. Core scope • Design and code a clean, modern Android native app (Kotlin or Java) that opens with a simple onboarding flow, then serves structured lessons on Android development fundamentals. • Integrate quizzes or mini-tests so learners can check understanding after each topic. • Track user progress locally and sync it to the cloud so they can pick up where they left off. Why location matters Face-to-face sessions will speed up architecture decisions, UI reviews, and peri...

I’ll supply the civil engineering standards and the specific formulas the reckoner should reference; you conver...

On my WordPress site, built with a premium theme, the footer behaves oddly on phones held in portrait mode. When I reach the very bottom and begin to scroll up, the view suddenly snaps up to the “Our Services” <h3> heading instead of moving smoothly. I haven’t knowingly added any footer-specific custom code or plugins, so I need someone to: • trace the exact cause—whether it’s theme JS, a plugin, or rogue CSS overflow rules • correct the issue so scrolling in the footer is smooth in mobile "media portrait orientation".

Need a Web App designed for mobile, removed from Base44 to React Native. I created a mobile app using Base44 and is currently hosted in Base44, with storage in S3, Lambda in AWS, but want to get it to be full mobile app to be on App Stores. Ned an experienced developer who has done this type of extraction and rebuild before. Need to see working examples.

I need an experienced iOS developer to embed a fully-functional “mod menu” into my existing Swift/Objective-C app. The menu’s sole purpose is user-centric customization, not cheats or debugging tools. Core requirements • Appearance / theme tweaks – the menu should let users change on-screen visual values at runtime (colours, font sizes, maybe even light-dark variants) and see the result instantly. • Control adjustments – simple options to remap or tune in-app controls (e.g. button placement, sensitivity sliders). Implementation notes • The menu must feel native and stay hidden until invoked by a discreet gesture or icon. • Persist all user selections with UserDefaults or a lightweight local store so settings survive relaunch. ...

I have the signed APK of an existing Android app and need it re-worked so the current UI/UX layout problems are resolved. No new features or visual theme changes are required—just a solid clean-up of the screens so they render and behave correctly on recent Android versions and a range of device sizes. You will decompile the APK, correct the layout XML, update any related Java/Kotlin resources if they block proper rendering, and then rebuild and re-sign the package. I expect the fixed APK plus the modified source set so I can continue development internally. Deliverables • De-compiled project with updated UI/UX layouts • Re-signed, installable APK showing the corrected interface • Brief change log outlining what you touched I can provide the current APK and ...

$100 fixed job ! picking up HungerQuest again after a short pause. need someone to come in, review where the codebase is at, handle some small UI fixes and updates, and get the app deployed to TestFlight and eventually App Store and Play Figma files, working from the existing screens and verbal direction. previous developer did solid groundwork but a few things need tidying before it is ready for for someone with React Native experience who also brings a bit more to the table, ideally familiar with market research integration, audio services, and multilingual support (Arabic, Spanish at minimum). not all of these are immediate but want someone who can grow with the project.

I need an Android-only social media application built from scratch. The initial release must focus on robust user profiles: secure sign-up/login, editable profile pages with avatar, bio, and basic privacy settings. Code quality and a clean Material-compliant UI are essential because I plan to layer in messaging and photo/video sharing after this first version goes live, so the architecture must be modular and scalable. Please handle: • Full Android Studio project with readable, well-commented code • Compiled APK ready for testing on recent Android versions • Brief setup guide so I can run and build the project locally If you can also integrate basic analytics or push notifications, mention it—those could become follow-up tasks.

Hi, I’m looking for some help customising our Shopify product pages. Our website is At the moment, customers have to select one size at a time and add each item to the cart individually. This is causing friction and likely affecting conversions. We want a size quantity selector on product pages so customers can: Enter quantities for multiple sizes at once (e.g. 5 Small, 5 Medium, 7 Large, 10 XL) Then click one button to add everything to the cart Instead of selecting one size at a time, we’d like a simple layout like: Small [ 0 ] Medium [ 0 ] Large [ 0 ] XL [ 0 ] Customer enters quantities, then clicks: Add to Cart / Start Order This should add all selected sizes (with quantities) to the cart in one go. Must work on mobile (most of our traffic is mobile) Must work wi...

I’m building an Android-only application that mirrors the simplicity and speed of the Crex platform, but tailored to my own branding. The core sport is cricket and the must-have features are: • Real-time score updates that refresh seamlessly during every ball • Complete player statistics—career numbers as well as match-by-match performance • Short, in-app match-highlight clips once an over or innings is completed I’ll provide any design assets or style guidelines you need; everything else—from the mobile UI to the back-end scoring engine and API layer—should come fully implemented, tested, and ready for Play Store submission. At hand-over I expect: • The compiled APK plus source code, neatly organised and documented • A ...

I need an online store that lets customers order vinyl-wrap cabinet doors in both profiled and flat styles. Please use the linked page as a loose reference for flow and logic, but strip it back to only the essentials so the interface stays clean and extremely easy to navigate. All pricing is already set out in an Excel sheet; you’ll import that data so product sizes and options calculate automatically at checkout. Because these are vinyl-wrap doors only, there’s no need to show alternative materials— a few door profiles, edge choices where relevant, and quantity input. Core tasks . based if possible • Build a fast, minimalistic front end that works smoothly on mobile and desktop. • Map my Excel price list to the product configurator so customers see real-t...
