    I need a location-based geofilter activated on Snapchat for a single venue that serves as our community’s main gathering place. I already have the design concept sketched out; what I’m missing is the technical side—preparing the artwork to Snapchat’s specs, defining the exact geofence around the venue, submitting the filter through the On-Demand dashboard, and confirming it goes live without hiccups. Here’s what I expect from you: • Refine or recreate the artwork so it meets Snapchat’s PNG size, transparency, and resolution requirements. • Configure the geofence precisely around the landmark (I will share the map pin and radius). • Schedule the filter for the dates and hours I provide, submit it, and keep me updated until Snapchat app...

    My live app on both iOS and Android suddenly stopped talking to its companion website. All users now see loading errors where content used to appear. I haven’t changed the code or any server settings, and I’m not even certain what the original developer used to build the backend—WordPress, a custom stack, or another CMS are all possibilities. What I need is straightforward: diagnose why the mobile clients can’t reach or authenticate with the site anymore and implement a solid fix so content loads normally again on both platforms. You will likely inspect API endpoints, SSL certificates, DNS, hosting logs, or any middleware in the path, then patch or re-configure whatever is blocking the handshake. Once the app is successfully pulling live data on iOS and Androi...

    I’m building a mobile app whose sole focus is accurate astrological calculation and prediction. Users will enter their birth data and instantly receive personalised horoscope forecasts generated by an in-app calculation engine. The app must handle ephemeris look-ups, house and aspect calculations, then transform those results into clear predictive text that can be displayed in a clean, modern UI. The core I need from you is the algorithmic backbone—think Swiss Ephemeris-level precision—wrapped in a stable cross-platform shell (Flutter or React Native are both fine; if you have a better suggestion, let’s discuss).

At this stage I only require the core one-to-one text conversation flow; once that is solid I may extend it to voice notes, file exchange, or group rooms, but those extras are not part of this first milestone. Here is what I expect: • A clean Android Studio project written in Kotlin (Java is fine if you strongly prefer). • Real-time send/receive with message status indicators.

    I want to bring a fresh social-networking experience to life and need a complete mobile app that runs smoothly on both iOS and Android. The core of the product is a robust User-profile system—think clean onboarding, editable bios, avatars, privacy controls, and a profile-to-profile follow mechanism. From sign-up to profile customization, everything should feel fast, modern, and secure. Cross-platform delivery is essential. If you prefer Flutter, React Native, or another proven framework that keeps one code-base in sync across the two stores, let me know your reasoning; I’m open as long as the final apps meet Apple and Google submission standards. Key requirements • Native-level performance and polished UI/UX that aligns with current iOS Human Interface and Android Mate...

    I have an internal voter-engagement app already running on AppSheet that holds roughly 175,000 records. Ten team members use it today, and I expect that number to reach about 500 over the next twelve months, so stability and performance at scale matter.

    I’m building a new mobile app that helps users organise and complete remote tasks, and I need a cohesive set of realistic illustrations that will give the interface a polished, trustworthy feel. Each illustration should align with common in-app moments—onboarding screens, empty states, success messages, and quick tutorials—so users intuitively understand what to do next.
