LetGo helps you quit unhelpful habits and build better routines without all-or-nothing pressure. Most habit trackers make one missed day feel like failure. LetGo is more than a tracker: it's a calmer, more supportive way to change. Adaptive Habits creates realistic weekly goals that adjust to you, your progress and pace, helping you keep moving forward when life gets messy. No guilt. No starting over. Whether you want to reduce smoking, drink less alcohol, spend less time scrolling, exercise regularly, read more, meditate, sleep better, or drink more water, LetGo gives you a clear, supportive plan for lasting change - one that adapts when life does not go as planned. Building habits with LetGo feels less like using another productivity tool and more like an evolving journey you actually enjoy showing up for. Our Balloon and Stone metaphor makes progress feel visible: build good habits that lift you up, and let go of the habits that hold you down. This isn't just another checklist, it’s an evidence-based approach to lifestyle and habit design. KEY FEATURES • Adaptive Habits: Set a pace that feels achievable. Your weekly goals adapt to your successes and struggles, helping you build consistency without burnout. • Pressure-free progress: Built on principles of behavioral psychology and the science of "small wins." Slip-ups happen. Instead of killing your streak, LetGo recalibrates your path to keep you moving forward.| • Quit & Build: Work simultaneously on leaving behind habits that hold you back while building routines that support the person you want to become. • Cloud Sync & Security: Never lose your progress. Your data is automatically saved to the cloud, keeping your progress safe and available across your devices. • Insights and statistics: Understand your consistency, spot patterns, and see how your habits change over time. • Gentle reminders: Stay mindful of your plan with reminders designed to help you return to your habits at the right moment. • Unique and simple design: We’ve stripped away the clutter. Enjoy a clean, intuitive interface designed to reduce cognitive load, so you can focus entirely on your habits, not the UI. • Dark & Light modes: Whether you’re setting goals at dawn or reflecting at midnight, our beautiful Dark and Light modes ensure a comfortable experience for your eyes at any time of day.
