# Calistree > Calistree is a free, all-in-one fitness app for iOS and Android. It started as a calisthenics (bodyweight strength) app and grew into a full training platform covering bodyweight, weights, cardio, mobility, balance and yoga. It builds personalized, adaptive workout plans from a user's goals, available equipment and schedule, and keeps adjusting them as the user progresses. No ads, free with no time limit; an optional PRO tier raises some limits. Calistree is made by Calistree LLC, a small, founder-led company based in Raleigh, North Carolina, USA.

Building Calistree since 2021. Originally built the app because he could not find the training tool he wanted for his own calisthenics practice. - Mission: help people exercise in a safe, efficient and enjoyable way, for a long, healthy and happy life. - Core values: Connection (exercises are connected, and so are the app's users; the tree in the logo represents this), Health, Consistency, Variety. - Small team; every support channel reaches the same people, who typically answer within two days. ## Contact - [Email](mailto:info@calistree.com): info@calistree.com, for support and general questions. - [Feature requests and bug reports](https://feedback.calistree.com/): public feedback board. - [Reddit](https://www.reddit.com/r/calistree/): community discussion. - [YouTube](https://www.youtube.com/@calistree): tutorials and updates. - [Instagram](https://www.instagram.com/calistree/) - [Facebook](https://www.facebook.com/calistree.official) ## The app - Platforms: iOS and Android (native mobile apps), plus a [companion web app](https://calistree.app) for browsing the exercise library and managing an account/purchases from a browser. - Disciplines covered in one app: bodyweight/calisthenics, weight training, cardio (HIIT and steady-state), flexibility and mobility, yoga, partner acrobatics, handstand training, muscle-up training, and more. Every exercise is scored on four qualities (strength, flexibility, cardio, balance) so the app understands how it fits with everything else. - Exercise library: 1,800+ exercises, each filmed on video, searchable by muscle, joint, equipment and difficulty. - Personalized training plans: the user sets goals and training days, tells the app what equipment they have per location (home, gym, park), and Calistree generates a multi-week training block matched to their level. Routines evolve automatically as the user gets stronger. - Skill trees: visual progression paths from a user's current level to an advanced skill (e.g. handstand push-up, muscle-up), one variation at a time. - Automatic progression: personal records, mastery tracking and experience points; the app levels up a movement as it is mastered. - Muscle recovery map: shows which muscles are fresh, recovering or fatigued before a session. - Kal: an in-app AI trainer that can suggest exercise swaps and next steps during a workout. - Health app integration: exports workouts to Apple Health (iOS) and Health Connect (Android), tagged with the right workout type per discipline. - Localization: available in 16 languages, including English, Spanish, French, German, Portuguese and Japanese. - Ratings (as displayed on the marketing site): 4.9 on the App Store, 4.7 on Google Play, 500K+ downloads. ### Download - [App Store](https://apps.apple.com/us/app/calistree/id1558561315): iOS download. - [Google Play](https://play.google.com/store/apps/details?id=com.calistree.calistree): Android download. - [Universal install link](https://link.calistree.com/get): opens the right store for the visitor's device. ## Pricing - Free tier (forever, no ads, no time limit): unlimited workout sessions, the full 1,800+ exercise library with video, automatic progression, every discipline, 2 routines, 2 equipment profiles, 2 training plans, 3 custom exercises, 3 custom flows, 1 workout buddy, 3 Kal (AI trainer) messages per month. - PRO tier: everything in Free, plus far higher limits (50 routines, 50 equipment profiles, 50 training plans, 250 custom exercises, 250 custom flows, 30 workout buddies, 30 Kal messages per month) and unlocks color themes. - PRO prices (USD list price; actual price varies by country/currency/tax): $5.99/month, $44.99/year, or $179.99 one-time for lifetime access. - PRO can be purchased in-app via the App Store or Google Play, or on the web at the account page.
