Offer description

Freelancers only – no agencies please. I’m looking for an experienced Flutter developer to build an MVP mobile app (iOS & Android) for my UK business Leather Academy. This is a practical, professional tool, not a startup experiment. No logins, no subscriptions, no backend, no AI marketing fluff. ⸻ What the App Needs to Do Core Features 1. Hex colour input colour wheel 2. Preview colour on leather textures 3. Save swatches locally (Hive or similar) 4. Swatch library (view / rename / delete) 5. Export & share PNG including: • Colour preview • Hex / RGB / HSL • name • Date ⸻ Required Advanced Features 6. Camera / photo colour matching • Take a photo or choose from gallery • Tap an area to sample colour • Average pixels for stability • Convert to hex / RGB / HSL • Save sampled colour as a swatch 7. Pigment mixing calculator • Batch size presets: 30 / 50 / 100 / 250 / 500 / 1000 ml custom • Add pigments by % or parts • Auto-calculate ml per pigment • Save formulas ⸻ Tech & Build Requirements • Flutter (single codebase for iOS & Android) • Local storage (Hive preferred) • Camera & image processing • Export/share image generation • Clean, readable, well-structured code ⸻ Branding (Must Follow) • Navy: 0B1F44 • Gold: D4AF37 • Cream: F9F7F3 • Font: Montserrat ⸻ Deliverables • Full Flutter source code • Git repository transferred to client • Android build (APK/AAB) • iOS project/build • Basic setup documentation • 30-day bug-fix support after delivery ⸻ Ownership & IP (Important) This is work made for hire. • I own 100% of the code and IP • The app and code cannot be reused or resold • Final payment only after full handover Can pay in stages If you’re not comfortable with this, please don’t apply. ⸻ How to Apply Please include: 1. Links to 2–3 Flutter apps you’ve built 2. Fixed-price quote for this MVP 3. Estimated timeline 4. A short explanation of how you’ll implement camera colour sampling Please start your proposal with the word “LEATHER” so I know you’ve read the brief.
