Original Purpose: As a developer, I once felt that most planning apps on the App Store were hard to use. They didn’t truly visualize goals and progress, nor did they effectively motivate users. After conducting surveys and research into what people really need, I created this app. The core idea is to make every check-in for your plan feel direct and rewarding, while also giving you great encouragement. I hope you find it both handy and enjoyable to use. Some Quick Tips: First, TOP plan is the most important one. You can set your most urgent plan as a TOP plan. To help you focus better, you can only have one TOP plan at a time. The app also offers a variety of widgets that you can freely combine and place on your home screen for quick access. Some of these widgets even include buttons for direct actions, so you can operate them without opening the app. Everything is designed with your needs in mind, and I believe you’ll make great use of it. You are very welcome to join our Discord group to share any thoughts or feedback you have.
