<p><b>Startup description</b></p><p>This product is a mobile iOS app that allows users to send documents as faxes directly from their phone without using a physical fax machine. The app is designed for business users, freelancers, and professionals who need to send contracts, invoices, signed documents, PDFs, and other files quickly and securely.</p><p>The app supports importing PDFs and images, adding an electronic signature, previewing documents before sending, and tracking fax delivery status. It is positioned as a simple mobile productivity tool for users who still need fax communication with offices, banks, agencies, and business partners.</p><p>The project was launched on October 30, 2025, as part of our mobile app portfolio focused on useful subscription-based iOS tools. The app already generates recurring revenue and has a lightweight structure with no custom backend.</p><p><b>Key highlights:</b></p><p>• MRR May 2026: $426</p><p>• Proceeds March 2026: $378</p><p>• Proceeds April 2026: $384</p><p>• Annualized revenue prediction based on current MRR: ~$5,112</p><p>• Main operating cost based on usage: iFax API — from $27/month</p><p>• Annualized operating cost: ~$324</p><p>• Estimated annualized profit after API cost: ~$4,788</p><p>• Estimated business margin after API cost: ~93.7%</p><p>• Backend: No</p><p>• Tech stack: Swift</p><p>• Publication date: October 30, 2025</p><p><b>Team</b></p><p>The app was developed and managed by an experienced mobile app team. Responsibilities include iOS development, product management, ASO, App Store operations, design, monetization setup, and buyer support after the sale.</p><p><b>Tech Stack</b></p><p>The app is built with Swift for iOS. There is no custom backend, which makes the project simple to maintain and easy to transfer. Fax delivery functionality is powered through the iFax API, which currently costs $27/month.</p><p><b>Marketing and growth</b></p><p>The app has been promoted mainly through paid acquisition. The product is in a practical business utility niche with clear user intent: people search for fax apps when they need to send documents urgently from their phone.</p><p>There is still room for further growth through Apple Search Ads, Google App Campaigns, improved ASO, localization, better screenshots, and paid traffic testing in Tier-1 countries.</p><p><b>Revenue and profit</b></p><p>The app is already generating recurring subscription revenue. Proceeds were $378 in March 2026 and $384 in April 2026, with the current May 2026 MRR at $426.</p><p>Based on the current MRR, the app has an annualized revenue run-rate of approximately $5,112. Since there is no backend and the only required fixed cost is the iFax API at $27/month, the estimated annualized profit after API cost is approximately $4,788 before taxes and marketplace/platform fees.</p><p><b>Return on investment</b></p><p>The project is suitable for a buyer who wants to acquire an already launched iOS utility app with existing revenue, source code, design assets, website, and operational setup included.</p><p>A buyer can improve ROI by scaling traffic, improving ASO, testing Apple Search Ads, optimizing the paywall, and increasing conversion from install to subscription. Since the app has low fixed costs and no backend, most additional revenue can contribute directly to profit.</p><p><b>Startup assets</b></p><p>• Full source code</p><p>• Website</p><p>• Domain</p><p>• Corporate mailbox</p><p>• Figma design</p><p>• Support after sale</p><p>• Existing App Store product</p><p>• Current monetization setup</p><p>• Lightweight operating structure with no backend.</p><p><b>Risks</b></p><p>The main risks are related to App Store competition, subscription churn, dependency on the third-party iFax API, and the need for continued marketing or ASO improvements to grow revenue.</p><p>Buyers can reduce these risks by keeping the app updated, maintaining API access, improving store assets, testing paid acquisition carefully, and monitoring subscription metrics.</p><p><b>Summary</b></p><p>This is a simple and lightweight iOS business utility app with existing recurring revenue, low operating costs, no backend, and clear growth potential. It is a good fit for a buyer who wants to acquire a ready-made mobile fax app and focus mainly on marketing, ASO, and monetization improvements instead of building a new product from scratch.</p><p>✅&nbsp;$940 TTM revenue</p><p>✅ 14 customers</p><p>✅ Business model: SaaS+Credits</p><p>✅ Built with Swift, UIKit</p>
