MuscleTools
Read full descriptionHide full description
No unnecessary complexity, personalization hype or subscriptions. MuscleTools is simply the app I wanted to use myself, with tools and resources for a fit lifestyle. Tools like: - Exercise for each muscle (visualised on a human body) - Exercise instructions - Soreness timer - Tabata timer Resources like: - Simple supplements information (no affiliations or other bs) - Niche workout routines (e.g. for climbers, runners, swimmers etc) Note: Information in the app is based on a mixture of AI-generated content and personal online research. I am in no way any expert or professional, but have a general interest in fitness and nutrition. Always consult with a medical professional before attempting any lifestyle changes regarding supplements or otherwise.
