<p><b>Startup description</b></p><p>Track your fitness evolution with precision. Measurements, progress photos, charts, and GLP-1 treatment control for smarter, consistent weight loss.</p><p>Easily record and track waist, hips, chest, arms, legs, and other key measurements over time.</p><p><b>Key highlights:<b></b></b></p><ul> <li><b>Annual revenue:</b> $300 - $600 (Current low-monetization phase)</li> <li><b>Annual profit:</b> $300 - $600 (Minimal infrastructure costs)</li> <li><b>Lifetime revenue:</b> $375</li> <li><b>Churn rate:</b> 3-5% (High user retention)</li> <li><b>LTV:</b> ~$15 (Based on current one-time purchases/ads)</li> <li><b>CAC:</b> $0 (100% Organic growth via ASO)</li> <li><b>Business margin:</b> ~95%</li> <li><b>Users:</b> 6,900+ registered users.</li> </ul> <p><b>Team</b></p><p>The project is a solo venture. As a Senior Flutter Developer, I am responsible for the entire lifecycle: UI/UX design, frontend development (Flutter/Dart), and backend architecture (Firebase).</p><p><b>Tech Stack</b></p><ul> <li><b>Frontend:</b> Flutter &amp; Dart (Single codebase for iOS/Android).</li> <li><b>Backend:</b> Firebase (Firestore for real-time data, Firebase Auth for security).</li> <li><b>Storage:</b> Firebase Cloud Storage for user progress photos/videos.</li> <li><b>Architecture:</b> Clean, documented code following industry best practices.</li> </ul> <p><b>Marketing and growth</b></p><p>Growth has been <b>100% organic</b>. The app was optimized for App Store Search (ASO), which consistently brings in new users daily without any paid advertising. This proves a strong product-market fit and a high demand for the "body metrics" niche.</p><p><b>Revenue and profit</b></p><p>The app currently generates ~$50/month. While the current ARR is modest ($600), the <b>Retention</b> is high and <b>CAC</b> is zero. The profit margin is extremely high because the Firebase backend stays within or near the free tier/low-usage brackets even with thousands of users.</p><p><b>Return on investment</b></p><p>The payback period is estimated at <b>12-18 months</b> at the current revenue. However, a buyer can achieve an <b>instant ROI increase</b> by:</p><ul> <li><b>Android Launch:</b> Using the existing Flutter code to capture the Google Play market.</li> <li><b>Paid Ads:</b> Scaling the proven organic conversion with Meta/Google Ads.</li> </ul> <p><b>Startup assets<b></b></b></p><ul> <li><b>Full Source Code:</b> Proprietary Flutter/Dart codebase.</li> <li><b>Database:</b> 6,900+ registered users and their historical body metrics.</li> <li><b>App Store Account:</b> Transfer of the live app on the Apple App Store.</li> <li><b>Backend:</b> Full ownership of the Firebase Project.</li> <li><b>Branding:</b> All logos, icons, and UI design assets.</li> </ul> <p><b>Risks</b></p><p>The main risk is the competitive fitness market. However, this is minimized by the app's established organic ranking (ASO) and the "sticky" nature of the data—users who have logged months of progress are unlikely to switch to another app.</p><p><b>Summary</b></p><p>You should buy my app because it is a <b>proven technical asset with a massive "sleeping" audience</b>. You aren't just buying $50/month; you are buying a polished, custom-coded platform with <b>7,000 users</b> that is ready to be turned into a high-MRR SaaS. It’s the perfect "plug-and-play" project for a marketer or entrepreneur who wants to skip the expensive $15k+ development phase and go straight to scaling.</p><p>✅ $375 in Annual revenue</p><p>✅ 6,900 customers</p><p>✅ Business model: IAP</p><p>✅ Built with Flutter, Firebase, Google Firestore</p>
