MonMenuSain is an iOS application designed for French users to navigate fast-food menus while pursuing their health goals. The app allows users to view nearby restaurants, receive personalized menu suggestions scored on their health impact, and check if meal combinations are compatible with their dietary macros. Users can also save their favorite dishes for future reference. It covers major fast-food chains and verifies nutritional data from official sources. Launched in late March 2026, the app experienced organic growth, hitting a Monthly Recurring Revenue (MRR) of €100 by May and achieving over 8,250 downloads. TikTok played a significant role in this growth, generating over 6 million views, with revenue peaking at €585 in June. The business faced a decline as content production on TikTok paused for a new project focus. The current MRR stands at approximately €300 with 89 active subscriptions and around 120 new users monthly, despite the content hiatus. The package for sale includes the full app and its code, verified nutrition database, established paywall, and branding assets. A comprehensive content playbook and a month's handover support are offered. An ideal buyer is envisioned as a French-speaking content creator or nutrition expert able to post thrice weekly on social platforms to leverage growth. Growth opportunities lie in resuming content, expanding restaurant options, and potentially testing paid advertisements. Despite challenges in adding new restaurants due to manual data entry, this remains a competitive moat. The business, with expenses around €35/month, is being sold to free up focus for a new endeavor, with revenue traceable through RevenueCat and App Store Connect.
