Hi, I need a simple method to send an APK file to approximately 2,000 WhatsApp contacts using an approved WhatsApp message template. My only requirement is to send the approved template along with the APK file. I do not need a dashboard, CRM, or any other additional features. Please confirm whether this is technically possible through the official WhatsApp Business API and share the method, cost, and timeline. I am looking for a freelancer who has experience with WhatsApp API templates and APK file delivery.

A simple fees management app...just student name , month, fees paid or unpaid, and auto whatsapp reminder

I have a steady stream of handwritten notes that need to be digitised directly inside our in-house Android app. Your task is simple and fully remote: open the mobile application, use its built-in camera scanner to photograph each page, and then type the visible content into the text fields the app provides. Accuracy matters more than speed, so I’m counting on careful transcription, correct spelling, and faithful formatting (line breaks, bullet points, etc.). Good lighting when you take the photo makes the work easier for both of us, so please check each scan before you start typing. When you finish a batch, just hit “Submit” in the app—no extra files or emails required. I review entries daily and will approve them quickly if everything matches the source. If you ...

I want to turn key paediatric guidance into a smartphone experience that helps parents stay on top of their child’s growth and wellbeing. The app’s core purpose is Educational, so every screen should teach, reassure or prompt sensible next steps rather than entertain or manage medical records. Primary audiences are parents and carers of children from birth to roughly twelve years old, so navigation, colours and language must feel welcoming to adults while still reflecting a kid-friendly theme. Content requirements • Developmental milestones – an easy way for parents to check what to expect at each stage and log observations. • Parenting tips – bite-sized, evidence-based suggestions that appear context-ually (e.g. “4-month tummy-time ideas”). ...

I’m starting this project from a blank folder and need a fully responsive website crafted with pure HTML5, CSS3 and Vanilla JavaScript. My priority is a clean, modern UI that feels just as smooth on a phone as it does on a desktop. Core features I’m looking for: • A modern, accessible navigation menu (I’m flexible on whether it’s horizontal, vertical or hamburger, as long as it looks sharp on all screen sizes). • An interactive Services section that highlights what we offer with subtle, elegant motion. • A dynamic contact form that validates fields in-browser before submission and provides clear inline feedback. The site should include tasteful CSS transitions—think gentle fades or slides rather than flashy effects—and all comp...

I need help repairing a responsive glitch that only shows up on mobile phones. On the homepage the layout breaks—sections slip out of place, spacing collapses, and the overall flow looks nothing like the desktop or tablet versions, which both render perfectly. Your task is to dig into the existing HTML, CSS and any related JavaScript, identify exactly why the mobile breakpoint misbehaves, then deliver clean, tested code so the homepage looks polished on common iOS and Android devices. Please make sure your adjustments do not disturb the tablet and desktop views. Deliverable: updated stylesheet (or component-level overrides) and a short note of what was changed so I can keep the repository in sync. Feel free to use Chrome DevTools, Safari responsive mode, or any framework-specific d...

Saya ingin membangun sebuah aplikasi Android sederhana yang berfokus pada fungsi login pengguna. Aplikasi ini hanya perlu menampilkan layar pendaftaran, layar masuk, dan satu halaman beranda kosong setelah autentikasi berhasil. Ruang lingkup pekerjaan: • Merancang antarmuka login & registrasi yang bersih dan responsif (XML / Jetpack Compose diperbolehkan). • Mengimplementasikan autentikasi email-password (Firebase Authentication, atau solusi backend ringan lain yang Anda sarankan). • Menyimpan data pengguna dasar (nama, email) di Firebase Realtime DB, Firestore, atau tabel MySQL—silakan pilih pendekatan yang paling efisien. • Menangani validasi input, pesan kesalahan, dan sesi pengguna sehingga pengguna tetap masuk saat aplikasi dibuka kembali.

I want to turn key geometry topics into a series of self-contained, interactive exercises that hold the attention of 13- to 18-year-olds and guide them from basic definitions through applied problem-solving. The material will live online, so everything must run smoothly inside a modern browser on laptops, tablets, and phones without extra plug-ins. Each exercise should let students manipulate shapes, drag-and-drop measurements, or toggle construction steps, then receive instant feedback that explains both correct and incorrect choices. Where possible, visual hints and short, in-context explanations should replace long text blocks; the goal is “learn by doing.” Deliverables • A collection of interactive geometry activities packaged as HTML5/JavaScript (or another lightw...

I run a small clinic and need a straightforward mobile application that lets my team capture, store and pull up a patient’s complete medical history at any moment. The heart of the build is a structured medical-history module linked to a prescription writer, so a doctor can open a chart, review past notes, add today’s findings, then generate and save a new prescription—all from one screen. The app has to work smoothly on modern smartphones, store data securely on-device first, and give me an easy way to back up or export records (PDF for individual visits and CSV/JSON for bulk data). A quick search by name, phone number or patient ID is critical because we often look up a file while the patient is sitting in front of us. Appointment scheduling is not a must-have right no...

Based on the image you sent from the Freelancer app ("Tell us what you need done"), the text you should type into that empty box depends on what kind of project you want to post. Here are a few options you can copy and paste depending on what you need: —————————— Option 1: If you want to hire someone to edit a photo (like the church photo you mentioned earlier) I need a professional photo editor to edit a church photo. I want you to remove the background trees, replace them with a nice dramatic sky, enhance the lighting and colors, crop it nicely, and deliver a high-quality final image. —————————— Option 2: If you want to hire a Graphic Designer (Logo...

I need a complete Android-only mobile app built from the ground up for my project, Jamzith ja. The core idea is defined, yet the feature set still needs to be refined and transformed into an intuitive, production-ready experience. I’m looking for a developer who can guide the process end-to-end—brainstorming UX, translating it into clean Kotlin or Java code, and delivering a signed release build on Google Play. Key deliverables • Interactive wireframes and UI designs approved before coding begins • Native Android app coded with modern SDK practices and a modular architecture • Integrated analytics and crash reporting, plus responsive layouts for phones and tablets • Ongoing commits to a private Git repo and clear documentation for future maintenan...

Subject: Senior Full-Stack Mobile Engineer for Luxury Multi-Language Ride-Hailing Platform (Flutter / React Native) Hi Developers I’m launching a high-end private ride-hailing service tailored for a specific regional market, and I’m looking for an elite mobile developer to bring it to life. I’m not interested in a messy prototype or a generic, clunky template. The vision is to build something that feels genuinely world-class—fluid, visually stunning, and as effortless to use as Uber, but with a sharper, more refined aesthetic. The interface needs to be clean, intuitive for everyday users, and completely frictionless from the moment someone opens the app to when they complete a ride. What We Are Building: The Passenger Experience: A gorgeous, minimalist UI with a ...

Run a quick end-to-end check of our live Hutch mobile service using a Hutch SIM physically located in Sri Lanka. You may use either an Android or an iPhone—whichever is easier at the moment—and rely on the phone’s built-in screen recorder so the video shows every tap, SMS, and the Hutch network indicator throughout. The flow is simple: 1. Subscribe to the service through one of the live portals: 2. Immediately unsubscribe. 3. Save the raw, unedited recording. Acceptance criteria • Network indicator clearly shows Hutch at all times • Full subscription journey, each SMS sent/received, and the unsubscription confirmation are visible without cuts or skips • Raw video file is shared, plus a brief two-to-three-sentence note stating the time ...

I need fresh eyes on my Android app to track down stubborn “App Not Responding” crashes. To reproduce the issue reliably you will log in with several different Gmail accounts, so please come prepared with at least three active addresses. Here is what I am looking for: • Install the current APK on a real Android device (not an emulator). • Use each Gmail account to sign up, navigate through every screen, and trigger heavy-use scenarios that might freeze the interface. • The moment the app hangs, capture a full logcat trace, note the steps that led up to it, and grab a quick screen-recording if possible. • Repeat until you can no longer reproduce the freeze or you have isolated a clear pattern. Deliverables 1. A concise test report listing every ANR...

I am building a mobile-first e-commerce application whose initial release focuses purely on a browsable product catalog. This is a mobile app project, not a responsive website, and the core objective right now is to give users an attractive, fast, and searchable catalog experience. What I need from you is an MVP that runs smoothly on both iOS and Android (React Native or Flutter are both fine). Because it is strictly catalog-only at this stage, there is no shopping-cart flow or payment gateway to wire up, but please lay the architecture out so those elements can be added later without a full rewrite. Key areas I will review: • Clean, modern UI that matches standard e-commerce patterns • Efficient data handling for categories, variants, and images • Simple admin o...

I’m looking for an experienced Android developer to build a grocery delivery application from the ground up. The app should run smoothly on Android phones and tablets, guiding a customer from product browsing all the way to order confirmation and delivery. At minimum, the flow needs to cover browsing a live catalogue, adding items to a cart, scheduling or requesting immediate delivery, and checking out securely. I’m open to your recommendations on tech stack—whether that’s native Kotlin, Java, or a cross-platform framework that still produces a polished Android build. Clean architecture, modular code, and thorough inline documentation are very important because my in-house team will take over maintenance once the project is live. Please include examples of previou...
