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 looking for a full-service partner to build a real-money online casino focused mainly on slot machines. I need the complete website—front end, back end, and game content—delivered production-ready. Game content • Slot machines are mandatory. • I’m open to either integrating trusted third-party slots or having comparable originals developed from scratch; suggest the most efficient route and justify it. Core platform requirements • Player registration, KYC, and account management • Secure wallet with multi-currency deposits and withdrawals • Provably fair RNG or relevant certification for all games • Admin dashboard for user, game, and finance oversight • Scalable architecture that handles high traffic without lat...
I already use a Twilio number for live API traffic on my website and Twilio confirms the line “supports WhatsApp Business.” SMS messages flow and the logs look clean, yet the Android WhatsApp Business app never receives a verification code when I try to link the same number. I’m looking for someone who has been through this exact activation loop and can pinpoint whether the block sits inside Twilio, Meta/Facebook Business Manager, or the WhatsApp onboarding sequence itself. You’ll have access to current Twilio logs and, if needed, I’ll share temporary Business Manager access so you can check display name approval, messaging limits, and any missing compliance steps. Acceptance criteria • The number completes verification inside the Android WhatsApp...
We currently have a Android App which has a interactive animation built in Java and Android XML, you can check what this animation looks like by clicking a topic in the app and then clicking any purple line. We want to add some panels on the homepage that displays each of the categories that we have and when these are panels are clicked we want these boxes to have a press animation. When the next page is loaded which has the topics for the chosen category that’s been selected we can split by latest etc. We may also want to change the page which lists all the topics into one topic per line and also animate the pressing of the topic in some way. I will share any further details required when we speak on chat. This may require you to add categories to our website database so that we c...

I need a complete Matka gaming solution built from scratch—a responsive web site plus a dedicated Android app. The core of both platforms is a smooth betting interface where players can pick numbers, place bids, and instantly see odds. As soon as the draw is over, the same ecosystem must publish results in real time, so latency has to be minimal. All users will come through a secure registration and login flow. I expect standard e-mail/phone verification, an encrypted password store, and basic account-management screens. An admin console should let me edit draw schedules, push results, view player activity, and manage payouts. For the Android side, follow current Material guidelines and make sure the app calls the same back-end APIs that power the site. I prefer you use a moder...

I’m ready to bring a new social-networking experience to Android and need a developer who can take it from concept to a polished, downloadable APK. The focus of this first release is simple but critical: real-time one-to-one and group messaging. Users should be able to register quickly, find contacts, and exchange text, images, and short videos with reliable push notifications. I’ll provide the basic wireframes and brand assets. You’ll turn them into a clean Material Design interface, build the back-end (Firebase or another lightweight, scalable solution you’re comfortable with), and hook up the messaging logic with end-to-end encryption. Key deliverables: • Full Android Studio project with readable, well-commented code • Secure user authentication, cl...
I need a vibrant, intuitive UI/UX created for an entertainment-focused digital product. The platform itself is still flexible—whether the final experience lives as a website, a mobile app, or a hybrid web app depends on where the concept shines best—so the design thinking should stay adaptive to multiple screen sizes. My top priority is a user journey that feels playful and fluid while remaining clear and accessible. Motion, micro-interactions, and bold visuals are welcome as long as they never slow the user down. Expect to move quickly from concept sketches through wireframes to a clickable high-fidelity prototype so we can validate flow and aesthetics before development. Deliverables I need from you: • Low- and high-fidelity wireframes covering all key screens •...
I want to launch a dedicated Android application that lets me sell my photographs directly to users.

Key features I need live in the first release: • User accounts with secure sign-up, social or email login, and a basic profile page • Built-in photo editing tools—crop, rotate, filters, and simple adjustments so customers can personalise images before purchase • Full payment-gateway integration (Stripe is my preferred choice, though I’m open to PayPal or another reliable option you recommend) for one-off photo purchases Deliverables I expect: 1. Production-ready APK plus al...
Senior iOS & Android Developers Wanted Build the Next Generation of a Parental Control, catch a cheapter & Device Management Platform The App can be installed in a very, very simple way, or, even if not installed, there should be a better way to access kids' or people's cellphones completely without iCloud access or anything else; that would be ideal.

I need you to finish a straightforward Revolut referral flow so I can unlock a bonus on my side and reward you with €50 on yours. You’ll be working with the link below and must follow each step exactly for the reward to track: !JUL1-26-AR-H1-REV-CTRL&geo-redirect What you’ll do 1. Open the link, sign up for a new Revolut account, and pass identity verification. 2. Top-up your new account by bank transfer (your stated preference). 3. Make three separate purchases of at least €5 each. Please avoid money transfers, gift cards, or gambling transactions—Revolut excludes those. 4. Order a physical Revolut card, then add that card to Apple Pay or Google Pay. Since you’re already comfortable with this step, no extra guidance is needed. Confirm...
My iPhone is at capacity and I need a careful clean-up that keeps every bit of my important information intact. Messages and WhatsApp data are my top priority, but I also want photos, videos, notes, and documents safeguarded. I already run regular iCloud backups and I have a Google Drive account, so you’ll be working within those ecosystems rather than introducing brand-new platforms. Here’s what I expect from you: • Audit the phone to pinpoint what’s consuming space, then walk me through the findings. • Create a full, verifiable backup—first to iCloud, then a secondary archive to Google Drive. • Upgrade or adjust my iCloud plan if needed and configure it so future backups run smoothly without duplicating data. • Off-load or archive large...

I want a straightforward mobile solution that lets boutique managers handle last-minute call-outs without headaches. The app must launch on both iOS and Android from day one and open straight into a clean flow where a manager can post an open shift, push it live, and then watch the responses roll in. Core experience • Managers create a shift card (date, time, pay, location, notes) and publish it. • Qualified associates receive an instant push notification, tap once to accept or decline, and the first confirmed response locks in the coverage. • Every user has a profile showing basic credentials, past ratings, and preferred boutiques so managers can review at a glance. • A lightweight in-app chat thread opens automatically between manager and confirmed staffer ...

# Partner With [App Name] — Distributor Opportunity Brief ## The Opportunity Voice technology is going mainstream — and [App Name] is built for the everyday consumer, not the tech elite. In a market crowded with complex, feature-bloated apps, [App Name] wins on one thing that matters most: **it just works, instantly, for anyone.** We're inviting a select group of online distributors to help us bring [App Name] to consumers through social media, e-commerce, and email — and share in the revenue as we scale. --- ## The Problem We Solve Most voice apps lose users in the first 60 seconds — confusing setup, unclear permissions, cluttered interfaces. Consumers give up before they ever experience the value. [App Name] removes every barrier: - **Zero-friction onb...

I’m ready to move fast on a complete mobile solution for our courier and transport operation. The project covers native apps for both iOS and Android, plus a lightweight web-based admin console if you feel it speeds up fleet oversight.

I want a single mobile application, running smoothly on both iOS and Android, that unifies day-to-day stock control with automated financial reporting. The idea is simple: I update purchases, sales, and closing stock on the go, and the app instantly reshapes those numbers into banker-ready statements—Balance Sheet, DSCR, CMA data, plus estimated and projected Balance Sheets.

I’d like a set of fresh, authentic-sounding App Store reviews that spotlight my iPhone app’s strengths and nudge new users toward downloading. The goal is straightforward: product promotion. I’ll provide the app link, a quick feature rundown, and a few existing comments for context. From there, I need you to craft multiple review snippets—varying lengths and tones—so we can rotate them over time without sounding repetitive. Each review should read as a genuine user experience, highlight the most eye-catching benefits, and avoid any language that might trigger Apple’s moderation filters. Once drafted, I’ll run them through a quick check and let you know if anything needs tweaking; otherwise, consider the project complete when I have a polished bu...

My current iPhone app needs a smoother, faster experience and a navigation flow that feels intuitive from the first tap. User-interface focus • Add clear, context-aware menus so key tasks surface naturally. • Strip down or merge cluttered menu items to keep journeys under three taps. • Build a more responsive search that returns results instantly and can filter as the user types.

# Project: Progressive Web App (PWA) for Kosher Supervision (Hashgacha) Management ## Project Overview I am looking for an experienced developer to build a **simple, secure, and easy-to-use Progressive Web App (PWA)** for a small kosher supervision (Hashgacha) organization. The system will be used internally by mashgichim (kosher supervisors) to manage businesses, perform inspections, record visit information, upload photos, and maintain inspection history. **I prefer a Progressive Web App (PWA) rather than separate iPhone and Android apps**, as it should work on phones, tablets, and computers through a web browser while still functioning like an installed app. The design should focus on **speed, simplicity, and ease of use**. --- # User Roles ### Administrator The Administrator s...
I need twelve Android users to help me measure how my app affects battery life during heavy, real-world use over a 14-day window.

I need a seasoned UX designer to help me rethink both my mobile app and its companion website with one clear objective in mind—dramatically increasing user engagement. The core flows are already in place, but interactions feel flat and users drop off after a few screens. Here’s what I’m hoping you can do: audit the current journeys, spot the friction points, and propose fresh, intuitive layouts that keep visitors tapping, scrolling, and coming back. Low-fi sketches are fine at first, but I’ll ultimately need interactive Figma prototypes that my development team can lift straight into build. Because this is as much about psychology as pixels, I’m looking for someone who can point to real-world results from past projects—tell me how your design decis...

Project Title: Senior Android TV / IPTV Developer for Custom Hardcoded App Job Description: We are looking for an expert Android TV / IPTV developer to build a custom, white-labeled, hardcoded IPTV application from scratch.

I’m gearing up for an ambitious “10 million – 10 × 10 ×” initiative and need a top-tier digital product designer to shape the entire user experience from concept to polished visuals. This is a pure digital play—no physical components or packaging—so every interaction, screen, and micro-animation must feel purposeful and seamless on web and mobile.

I’m rolling out a full-fledged hotel booking ecosystem that lives on three fronts: a customer-facing Android app, an iOS app, and a browser-based admin portal. The apps must let travellers search live inventory, choose an exact room (e.g., “Room 457” instead of a generic “Double”), pay securely, and leave ratings and reviews once their stay is over. Property data can never be stale, so real-time room availability has to stay in sync with external channels such as Airbnb and ; whichever API or iCal approach you prefer is fine as long as double-booking risk is zero. Each hotel owner will have an individual account with the freedom to update rates, photos, descriptions, blackout dates, and promotions at any moment without touching code. Multi-layer user per...
I want a custom digital planner built from the ground up so it isn’t just another off-the-shelf template. The core function is crystal clear: daily scheduling. Within each day I need three specific, fully integrated modules—Habit Tracker, To-Do List, and Time-Blocking—so I can move seamlessly from planning to execution without jumping between separate pages or apps. Format • The end product must simply be a custom digital planner. I’m flexible on the exact container (hyper-linked PDF, interactive tablet file, or another clever solution) as long as it opens smoothly on iPad/GoodNotes and similar note-taking apps and keeps hyperlinks intact.

Core experience The product centres on live, one-to-one HD video therapy sessions, real-time messaging/chat, and a completely automated appointment-scheduling flow that keeps therapists’ calendars and client reminders in sync. I also need an AI layer that can surface self-help resources, suggest next-step actions, and flag potential crises for clinical review—all while keeping user data encrypted at rest and in transit. Technical expectations Please architect for scale (micro-service...

I am setting up an online hub for buying, renting, and marketing pre-owned cars in the Atlanta area. The site must feel effortless for visitors: clean navigation, intuitive booking, and a checkout flow that works as smoothly on mobile as it does on desktop. Core functionality I need built and ready for launch: • Search and filter cars by make, model, price, and location • Rate and review cars after each rental or purchase • Schedule test drives directly from every listing At checkout, customers should be able to pay with credit or debit cards, PayPal, or a direct bank transfer.
