[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.

Ememo is a memory management app built around the Ebbinghaus forgetting curve and spaced repetition. It helps you revisit what matters through a clear, sustainable review plan. ⊕ We are not another to-do list or time-management app. ⊕ We are your memory companion, focused on three questions: How should I review? What should I review? How far have I progressed? 【PRODUCT HIGHLIGHTS】 · A proven approach: Automatically schedules effective spaced reviews based on the Ebbinghaus forgetting curve · Organized knowledge: Use folders and tags to add, classify, and manage different types of content · Visible progress: Track every review check-in and turn consistent effort into a motivating sense of progress 【LIGHTWEIGHT AND EASY】 · No registration required—open the app and start for free · A clean interface with a smooth, focused workflow · Add content, choose a memory cycle, and let Ememo handle the schedule · Review reminders mean you never have to calculate the next review time yourself 【MORE FEATURES】 · Create custom review intervals that match your own learning rhythm · Check progress and complete selected review tasks from Home Screen widgets · Explore multidimensional insights through heatmaps, streaks, total check-ins, and folder statistics · We plan to introduce the FSRS model in the future for more personalized review scheduling 【WHO IT IS FOR】 · Language learners who want to capture material and schedule reviews automatically · Anyone building a lasting study habit through structured review · Students preparing for graduate, civil service, professional, or certification exams · Memorizing vocabulary, texts, concepts, formulas, and professional knowledge · Organizing reading notes, course highlights, and knowledge from work Ememo does not study for you, and it does not promise that you will “never forget.” It simply brings important knowledge back at the right time, so learning goes beyond collecting notes. ⊕ Start with less friction ⊕ Enter review mode faster ⊕ Trust the power of repetition and turn “learned” into “remembered” One day, the knowledge will become part of you and you may no longer need Ememo. When something new is worth remembering, we hope Ememo is the first companion that comes to mind. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
