[What is Memory Helper?] Have you ever struggled to recall something when you needed it, even though you had memorized it? Forgetting is an inevitable objective law, but letting it happen is a huge waste of your own efforts. Fortunately, review is an effective way to fight forgetting. On the other hand, excessive review is also a waste of effort. For example, like constantly cleaning the ground which is already very clean. A lot of effort, but little effect. Memory Helper is a memory aid based on the Ebbinghaus forgetting curve, aimed at helping you review at spaced intervals and make effective use of your study time. [How do I use Memory Helper?] It's very easy to get started with Memory Helper. Add a memory, and Memory Helper will remind you to review at the right time. When you have further requirements, you will find that Memory Helper has provided solutions, such as: - If you want to use different review strategies for different types of memory materials, you can adjust the review curve. - If you forget to add memories when you finish memorizing, you can add them and modify the creation time at any time. - If you have more and more memories and want them to be well-organized, types (like directories) and tags are prepared. - If you want to locate a memory more quickly, just search for it. - If you don't want to type in characters, you can add images. And image editing is supported. - If you want your text to be more expressive, Markdown syntax is supported, and adding images is optimized specially. - If you don't want to review strictly in due date order, but want to review the same kind of memory first, the review interface supports filtering by type and tag. - If you want to browse reviews scheduled for the next few days to facilitate the arrangement of new memory tasks, a calendar view is prepared for you. - If you are overwhelmed by too many review tasks and want to give up, Intelligent Adjustment can adjust future review times based on when you review and how well you recall the material, helping you manage the workload. - If you want to change your phone, first sync your data to the server. Then log in to the same account on your new phone to access the data you have synced. There are many more features waiting for you to explore. [What isn't Memory Helper?] Memory Helper is not a panacea that guarantees you will never forget anything. It cannot do the remembering for you. You still need to memorize and recall.

Keep what you learn. Forget less. Study with less stress. Anti-forgetting Note is an app designed to help you keep the knowledge you have learned, without the stress of constantly worrying about forgetting it. It can be useful not only for studying, but also when you suddenly have a lot of new things to learn at a new job, when learning a new skill, or whenever you need to remember a large amount of information over time. Write down anything you want to remember as an Article. After reviewing it, predict when you think you will start to forget it, and set that date as your next review date. When that day arrives, review the Article again. Then, predict your next forgetting date and repeat the process. As you continue this cycle, something interesting happens: the intervals between reviews naturally become longer. Articles that once needed frequent attention gradually require less and less of your time. And this creates room for something even more interesting. As your review intervals grow, you gain the time and capacity to add more Articles. You can keep learning new things while the knowledge you have already acquired continues to be maintained in the background.
