This profitable iOS health app helps users maximize their height potential by combining AI-driven coaching with workout guidance, sleep tracking, nutrition support, and progress monitoring, and it’s built in Flutter so it’s Android-ready while supporting 30 languages; it has grown from $60 to $527 in MRR over the last 3 months entirely through organic TikTok content with zero paid acquisition, runs on weekly and yearly subscriptions via RevenueCat at roughly 74% net margins after platform fees and international taxes, and operates with zero infrastructure costs thanks to free-tier services, making it fully automated and solo-run with a proven content playbook, a largely untapped US market (most users to date are European), and the ability to launch on Google Play within days, as the founder is shifting focus to another project and wants an owner who can give it dedicated attention.
