MarkTodo is a Todolist APP that allows you to focus on starred to-dos. It displays your starred to-do in a double-column waterfall card style. MarkTodo currently supports the three major platforms of iOS/iPadOS/macOS, and supports iCloud synchronization of to-do items, allowing you to handle to-do items anytime, anywhere on any device. The original design intention of MarkTodo actually originated from my personal actual needs. In my daily work and life, many to-do items do not actually have a clear deadline, but this does not mean that these to-do items are not important. In contrast, most of the things that really matter don’t have clear deadlines. In traditional Todo tools, in order to reflect the importance of to-do items, deadlines are often used. However, deadlines can cause stress and often end up causing to-do items to expire... So, I was wondering, is there a to-do tool that can allow people to focus on important to-do items without causing time pressure? Therefore, I decided to develop MarkTodo, a todolist app that allows you to focus on starred to-dos. The core function of MarkTodo is the homepage, you can add to-do items that you think are important recently to homepage without adding a deadline. MarkTodo has several important features: - The homepage directly displays starred to-dos - Quickly add to-do without going inside the list - Add star and cancel star to-do at any time In addition, MarkTodo also provides all list pages similar to traditional Todo Apps, allowing you to get started quickly. Full functionality of MarkTodo: - Starred todos - Planed list - All Todo List - Done list - Custom list - Tag list - To-do priority - To-do reminder If you have any suggestions, please contact the developer: linguny@gmail.com ———————— MarkTodo Pro membership benefits: There are three MarkTodo Pro memberships, with any one of them you will have unlimited access to all MarkTodo features. - MarkTodo Pro Lifetime Membership (pay once, valid for life) - MarkTodo Pro Monthly Membership (monthly subscription) - MarkTodo Pro Annual Membership (annual subscription) Subscription price: Among them, MarkTodo Pro monthly membership and MarkTodo Pro annual membership are automatic subscription members, and the subscription price is subject to the actual price displayed in the AppStore.
