I accidentally wiped an entire WhatsApp conversation with a person from my Android phone and, to make matters harder, we have a backup but the chat was deleted by us so the backup also does not have any chat from that person. I also have not reinstalled the app yet because I want to avoid overwriting any residual data that might still be recoverable. What I need is a specialist who can safely extract or rebuild the deleted chat history from the device’s storage. Whether that involves forensic-style data carving, use of ADB, root-level tools, or other proven Android recovery software is up to you—as long as the approach keeps the phone usable and preserves any remaining data fragments. Deliverables should include: • The recovered chat thread, either restored directly insi...

I need an Android application that opens with a Phone Number Verification flow—OTP based—so every user is uniquely identified right from the start. After a successful sign-in, the core feature kicks in: each user must be shown Video ada, capped at ten ad views (or clicks to watch) per day. Once that quota is reached, the app should block additional ads for the next 24 hours and reset automatically at midnight. To monetise, I am happy to integrate Google AdMob, Facebook Audience Network, Unity Ads or any other website that can deliver rewarded inventory; pick the one that best meets the daily-limit logic and regional fill rates. Whichever SDK you use, make sure it respects Google Play policies, handles failures gracefully, and records impressions so the daily count cannot be ga...

I have a live mobile application that needs refinement rather than a ground-up rebuild. The core features are already in place; what I need now is a thoughtful upgrade that makes the current experience smoother, more reliable and easier to maintain. Your task is to dive into the existing codebase, identify areas that can be streamlined or modernised, then implement those improvements with minimal disruption to users. Whether that involves refactoring sluggish modules, tightening up API calls, polishing UI flows, or squashing lingering bugs, the aim is the same: deliver a noticeably better app without altering its core purpose. I’ll provide full access to the repository, current build pipeline and a list of pain points I’ve observed so far. From you I expect: • A concise...

Automatic Code Detection and Execution in Existing APK" Hello, I already have an existing Android Browser APK and its full source code, and I want to hire an experienced Android developer to customize it. Main requirement: automatic code transfer and execution without manual copy-paste. Example workflow: I open Telegram in the top half of my phone screen, open my APK in the bottom half in split screen or floating window. When I tap the code once in Telegram, it should automatically appear in the APK's "Code paste karo" field and execute automatically, with no manual pasting needed. Also, completely remove the "Sab IDs refresh – code hatao" button. Optimize the APK for smoother performance and faster page and tab loading, while keeping all existing featur...

I have all the visual pieces ready— decompiled table layouts, colourful card sets, buttons, and pop-ups taken from the reference app “Rummy R13.” What I do not have is the core game itself. I need you to turn those assets into a fully-playable, multiplayer 13-Card Standard Indian Rummy experience built with HTML, vanilla JavaScript on the front end, and Node.js + on the back end. Gameplay & rules • Follow the classic Standard Indian Rummy rule-set: 2–6 players, two decks with jokers, mandatory pure sequence, scoring at declaration, and drop/reshuffle logic. • Real-time multiplayer through rooms, with proper turn rotation, draw/discard, show validation, and point calculation. Flow & UI The look should stay colourful and engaging—exac...

I’m building an RCS business-messaging agent on AWS. Because AWS RCS is not yet available in India, I need one person whose mobile number is registered in the United States, the United Kingdom, Canada, any EU country, or Singapore to help me verify that everything works outside my region. Here’s the workflow we’ll follow: • After we start, you send me your real SIM or eSIM number (no VoIP services such as Google Voice or TextNow). • I add that number to Google’s official “RBM Tester Management” console and trigger an invitation. • You accept the invite, receive roughly five RCS messages, and tap the “Order refill” button inside one of them. • (Optional) you capture a quick screenshot of the message card with your own ...

This project is a straightforward, responsive portfolio site built entirely with HTML5, CSS3, and vanilla JavaScript. The primary focus is a “Projects” section where my work is showcased through embedded or hosted video presentations. Key points you should know: – Design must stay clean and minimalist, adapting fluidly to mobiles, tablets, and desktops without breaking layouts. – No external frameworks are required; pure HTML, CSS, and JS only, so that future edits remain simple. – All files must be clearly organised and commented to make updating colours, copy, or media painless. Deliverables 1. Fully responsive multi-page portfolio with a Projects page that supports video embeds/players. 2. Well-structured folder tree (, /css, /js, /media, et...

I need 12 testers for each of my 8 apps to complete the 14-day closed testing period. Screenshot verification is required. My total budget for all 8 apps is ₹1,000. Please let me know if this is possible within my budget.

I have eight lightweight productivity-tool apps that I need checked on real devices running the latest Android version. I’m looking for twelve reliable testers who can install every app, open each one once or twice a day for the next fourteen calendar days, and then send me timestamped screenshots that prove daily use. What to keep an eye on while you’re inside the apps: • User interface and design — make a quick note if anything looks off, unreadable, or inconsistent. • Performance and speed — flag unexpected hangs or slow first-load times. • Features and functionality — verify that the advertised core feature on the home screen actually works when tapped. At the end of the 14 days I need from you: 1. A zipped folder containing your d...

I need a small, single-user Android application called “Bhavit Halad Kharedi” that I can run entirely offline to track turmeric buying transactions. The workflow is straightforward: each time I purchase turmeric I must be able to enter the purchase date, trader’s name, weight in quintals, and the rate per quintal. The app should instantly calculate the basic cost, then let me add transport, hamali, brokerage (as a percentage), or any other expense so the total cost and the final cost per quintal appear automatically. Because I will open the app many times a day in the market, the interface has to feel clean and quick—nothing fancy, just a moderate design with a tidy layout and a few helpful icons so buttons and fields are easy to spot on a small screen. Records onl...

Je souhaite créer une application Android orientée productivité. L’objectif est de fournir un outil simple et intuitif qui aide l’utilisateur à organiser ses tâches quotidiennes, fixer des rappels et suivre ses progrès. Ce que j’attends : • Un premier croquis fonctionnel (wireframes) validant la navigation principale. • Un prototype APK permettant d’ajouter, modifier et cocher des tâches, avec synchronisation locale (aucun back-end pour l’instant). • Un code propre en Kotlin, prêt pour intégration future de services en ligne. • Une interface épurée respectant les directives Material Design, adaptée aux écrans smartphones et tablettes Android. J&r...

My Android mobile app’s Home screen is misbehaving: the view stops refreshing after the first load and several buttons that should lead to other parts of the app no longer respond. I need someone to dive into the existing codebase, pinpoint the root cause, and push a clean, well-tested fix right away so users can interact with the Home screen normally again. You will receive the full Android Studio project as soon as we start. After investigating, I expect you to update the code, test across common Android OS versions, and supply both an installable APK and the changed source so I can merge it back into the main repository. Acceptance will be based on: • Home screen refreshes consistently without manual intervention. • All previously unresponsive options are fully click...

Hi, I’m looking for a freelancer who can help implement push notifications for my existing app. Currently, my app only supports in-app notifications, so users can only receive notifications about new messages when they have the app open. I want to implement push notifications so users can receive alerts when someone sends them a message, even when the app is running in the background or closed. I’d like to know: If you can implement this feature in my existing app. What technology or push notification service you would recommend. How much you would charge for the full implementation. How long it would take to complete. Whether there are any additional ongoing costs or service fees. Please let me know your estimated price and what information you need from me to assess the p...

Hi, Can you develop the complete platform from scratch including Figma UI, frontend, backend, database, admin panel, and all required APIs? Tech stack: Flutter (Android and iOS), Backend. The platform will have two main roles: Owners can register and list their services or items, while Users can discover nearby listings based on their location and book services according to their needs. Can you implement location-based search, secure payment integration, booking and availability management, an AI chatbot, authentication, notifications, and an admin panel to manage users, listings, bookings, customer support, and payments? Full details or ideas behind this will not be disclosed here. But the flow is the same. Let me know if you are interested.

I’m ready to kick-off the first of several next-gen apps I have planned, and I want an experienced Indian team that can handle both Android and iOS builds from the ground up. The inaugural project is a social media platform focused on user profiles and content sharing with smooth photo- and video-upload capabilities. A modern, sleek look and feel is non-negotiable; think clean lines, intuitive navigation and animations that don’t get in the user’s way. While most collaboration can stay online, I’m based in Hyderabad and appreciate a team that can meet in person when a sprint review or brainstorming session really needs that face-to-face energy—totally optional but definitely a plus. Tech stack is your call as long as it delivers a performant, cross-platform ...

I have a small batch of Viber voice messages—fewer than ten—that I can no longer reach because Viber has cleared them to free up storage. Your job is to locate those files in the Viber backup or on-device storage, extract them without loss, and convert each one to a single, clearly audible MP3. Security is critical: I’ll provide temporary access, and I expect you to work on a local, offline environment, keep logs minimal, and delete every copy once I confirm receipt. Let me know the method you normally use (e.g., SQLite browsing, Viber desktop cache extraction, mobile root/Jailbreak with ADB/iTunes, etc.) and how you keep user data private. Deliverables • Up to 10 recovered voice messages in MP3 format • Brief note on the extraction steps you took so I c...

I want to turn my concept “Mimujer y yo” into a fully functional mobile e-commerce app. The core requirement is a smooth shopping-cart experience that lets customers add, edit, and remove items before checkout. I already know the app’s main goal—selling products—so I need someone who can take that objective and translate it into an intuitive, secure mobile application. Design the user flow around browsing a catalog, tapping an item, and moving it straight into the cart. Payment processing, account creation, and order confirmation screens should all support that flow without friction. If you have existing modules for product search, filters, or user reviews, let me know; they could become the next phase, but right now the shopping cart is the must-have deli...

I have an existing mobile app with separate Swift (iOS) and Kotlin (Android) codebases and I need a handful of targeted adjustments applied to both sides. Nothing ground-up—just concise edits, small feature tweaks, and a couple of bug fixes that surfaced during recent testing. The work will involve: • Updating the native Swift and Kotlin files where required • Ensuring parity between the iOS and Android builds so the changes behave identically • Compiling and testing each platform, confirming that new code doesn’t introduce regressions • Supplying the updated source and a brief change log so I can follow what was modified All code must compile cleanly with the current Xcode and Android Studio versions I’m using, and TestFlight / internal ...

I want to build a brand-new social media application exclusively for Android. The goal is to launch a functional prototype that lets users create accounts, post content, interact through likes and comments, and receive real-time push notifications. I need a developer who can handle the full Android stack—from designing clean, Material-styled screens to writing well-structured Kotlin/Java code and integrating a scalable backend (Firebase, Supabase, or a solution you recommend). Key expectations • Account creation and secure login (email, Google, or phone) • User profiles with editable bio and avatar • Infinite scrolling feed for text, photo, and short-video posts • Like, comment, and follow mechanics • Push notifications for follows, likes, and commen...

My Aspera handset is stuck behind Google’s Factory Reset Protection after I forgot the screen PIN and lost access to the registered Gmail account. I haven’t tried any technical work-arounds yet, so the phone is still exactly as it was when the FRP screen appeared. The warranty period has already expired, but I can supply a scanned proof of purchase to demonstrate legitimate ownership. I want the lock lifted so the phone powers on normally and lets me register a fresh Google account. Whether you achieve that through ADB commands, SP Flash Tool, custom recovery, or another proven Android service method is up to you; I only need a safe solution that won’t hard-brick the device. Acceptance criteria – once you say the job is complete I will: • boot the phone wit...

I have a set of already-approved UI/UX files that must be translated into clean, maintainable code for mobile screens only. Several pages are partly built, a handful of components still show visual glitches, and a few sections are missing altogether. All of that needs to be wrapped up inside a single, seven-day sprint. Your job is purely front-end: no design tweaks, no back-end hooks, just razor-sharp HTML5, CSS3 and JavaScript work (framework choice is up to you, provided the result matches the provided designs exactly). Every pixel, font weight and interaction has to mirror the mock-ups—no creative liberties. To help me gauge fit, tell me about similar mobile-first builds you have completed and the techniques or tools you relied on to hit pixel perfection under tight deadlines. A...

I’m building an AI-driven application whose core is a natural-language chatbot available both in the browser and as an Android app. I already have the product vision; what I need now is an engineer who can take it end-to-end—database, server logic, model integration, and polished interfaces—so users can converse seamlessly across platforms. The work centres on natural language processing, so you should be comfortable selecting or fine-tuning models, orchestrating inference, and exposing clean endpoints that a modern front end can call. Expect to set up the web client (React, Vue, or similar), craft a lightweight Android counterpart (native Kotlin or a robust cross-platform stack such as Flutter or React Native), and wire both to the same backend and database. Key delive...

I’m building a rental-model School ERP that must work both online and in patchy-network environments. The project is split into three tightly-integrated pieces that need to ship together: • Android Tablet APK – runs only in a secure kiosk / lockdown shell. Core modules are manual attendance tracking (checkbox beside each learner), student exam terminals, fee-receipt generation and teacher lesson tracking at the end of every period. The APK will be side-loaded, not published on Play Store, so an easy private-update mechanism and reliable offline/online sync are essential. • Web Hub – a browser app for Principals, Teachers and Administrators. It should let them maintain student & staff records, manage fee ledgers and pull one-click reports covering up to fiv...
