I need an end-to-end build of a wellness platform that lives on three fronts: a responsive website, an Android app, and an iOS app. The core purpose is to guide users through gym,yoga plans, nutrition guides, and mental-wellbeing content, all delivered through engaging interactive tools and calculators also with static posts or videos. Note- Backend Development is 70% completed including entire yoga/gym and nutrition section and major section of mental wellbeing Website scope • 5 main sections—each accessible from a clean, modern landing page. • Interactive elements such as calculators (e.g., macro or BMI), self-assessment quizzes, or planning tools integrated directly into the pages so users can generate personalised outputs on the spot. Along with it some free for commercial use meditation videos and frequency audios • Another CMS portal with separate admin, psychologist and one more login so I can monitor users, add or update plans, guides, and push for events registration without touching code. Mobile apps • Native or well-optimised cross-platform build for Android and iOS that mirrors the website’s structure. • Offline-friendly storage of selected plans and calculators for gym/yoga/ nutrition users with spotty reception. • Push notifications for plan reminders and newly published content. Look & feel I’m aiming for a calm, energetic aesthetic—think light colours, intuitive navigation, and clean typography—so users feel motivated rather than overwhelmed. Tech preferences I’m open to React Native, Flutter, or platform-specific stacks if you can justify the choice. For the site, a React, Next.js, or similar SPA is welcome, as long as SEO is not compromised. Deliverables 1. Fully functional website with domain deployment and admin access 2. Published Android and iOS apps (Play Store / App Store) 3. Source code and basic documentation covering environment setup, build steps, and how to add new calculators or articles 4. One short hand-over call or screen-share to walk me through operations Acceptance criteria • All sections load and function consistently across web and mobile. • Each interactive calculator returns accurate, validated results. • No critical accessibility or performance issues (Core Web Vitals in the green zone on desktop and mobile). • Store approvals achieved for both apps. If you have a track record in wellness or fitness tech, I’d love to see links in your proposal.
