VigiGym – The Intelligent Workout Tracker for iPhone &amp; Apple WatchVigiGym is a minimalist yet powerful fitness app built for serious lifters who value focus, precision, and design. Created entirely by a solo developer, it blends Apple’s design philosophy with the discipline of structured strength training.The app features a fully modular system that lets users build any workout routine – from straight sets to supersets, cluster sets, and drop sets – without templates or unnecessary clutter. Every muscle group is color-coded with a unique visual mapping system, offering instant feedback on which areas are trained.Unlike most workout apps, VigiGym doesn’t overwhelm you with social feeds or algorithms. It stays silent and efficient in the background, letting you focus on what matters most: lifting. With smooth sliders and dynamic 1RM calculations, tracking sets and weights becomes intuitive and fast — no typing, no friction.VigiGym also integrates seamlessly with Apple Watch, allowing users to view, log, and adjust their workouts directly from their wrist. All data is stored locally on-device — 100% offline, private, and secure.The app’s core is written in SwiftUI and powered by Core Data, designed with obsessive attention to visual detail and performance. Its creator, Achim Loobes, combines over 25 years of design experience with a lifelong passion for training and technology.VigiGym is more than a fitness tracker — it’s a handcrafted experience for those who want to train smarter, not noisier.App Store: <a target="_blank" rel="noopener noreferrer" class="break-all link-break text-gray-500 hover:underline" href="https://apps.apple.com/de/app/vigigym-workout-tracker/id6748325582">https://apps.apple.com/de/app/vigigym-workout-tracker/id6748325582</a>Website: <a target="_blank" rel="noopener noreferrer" class="break-all link-break text-gray-500 hover:underline" href="https://www.vigigym.com">https://www.vigigym.com</a>
