What Calistree does
Calistree is a privately held, bootstrapped software company that operates a freemium mobile fitness application focused on calisthenics and bodyweight training. The app, distributed globally on iOS and Android, serves individual consumers — primarily calisthenics enthusiasts ranging from beginners learning foundational movements to advanced athletes targeting skills such as front lever, planche, and one-arm handstand — and is designed to address decision paralysis and lack of personalization in generic workout programs by automatically generating and adapting training "Journeys" based on user objectives, equipment availability, and computed experience levels.
The core product is built around a proprietary graph database that structures relationships between exercises, muscles, joints, equipment, and objectives, with each exercise characterized by dozens of parameters. This data model powers a Skill Tree visualization for progression mapping, Experience Profiles that track strength, flexibility, balance, and cardiovascular capacity per muscle, and a Weak Link Identification feature that recommends targeted exercises to overcome specific plateaus. The exercise library has grown from roughly 800 exercises in 2022 to 1,350+ by late 2024, with monthly product updates (the app has reached its 300th iteration) and new content contributed by both the founder and users. The platform also includes a Community Page, Workout Buddies social feature, Knowledge Center for educational content, and integrations with Apple Health and Health Connect.
Calistree monetizes via a freemium model: the free tier provides unlimited workout sessions with constrained routine and customization limits, while Calistree PRO ($5.99/month, $44.99/year, or a one-time $179 lifetime license) unlocks expanded routines, equipment profiles, custom exercises and flows, buddies, and color themes. Distribution and growth are entirely product-led via app-store listings, blog content, a public feedback/roadmap board, and organic social channels (Reddit, Instagram, Facebook) — with no paid acquisition, sales team, or external capital. The company is operated by sole founder Louis Deveseleer, a Belgian-born former mechanical engineer who self-taught programming during the COVID-19 period and continues to develop the app while working part-time at another startup.
