[What is Memory Helper?] Have you ever had such an experience that it's hard to recall knowledge when you want use it, even you have memorized it? Forgetting is an inevitable objective law, but letting it happen is a huge waste of your own efforts. Fortunately, review is the most 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 auxiliary tool designed according to the Ebbinghaus forgetting curve aimed to help you review at the most scientific point-in-time and achieve the best results in the least amount of time. [How do I use Memory Helper?] It's very easy to get started with Memory Helper. Adding a memory, then 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 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 according to the expiration time order exactly, 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 in a few days to facilitate the arrangement of new memory tasks, calendar view is prepared for you. - If you are overwhelmed by too many review tasks and want to give up, the intelligent curve can help adjust each review time point, relieve the pressure but never compromise the effect. - If you want to change your phone, you don't have to worry about data loss at all. All the data is synchronized to the server. Just log in to the same account and the data is close at hand. There are much more features waiting for you to explore. [Memory Helper is not what?] Memory Helper is not a panacea to enable you not forget anything. It can not replace you to remember. You still need to memorize and recall.

See the note you need today the moment you check your phone. Memo is for short notes you look at repeatedly: shopping lists, things to bring, tasks for today, quick checklists, URLs, and small reminders you do not want buried inside a full note app. Select the notes that matter now and keep them available from the lock screen and Notification Center, so you can check them without opening the app and searching through a long list. Use it when a reminder is too heavy and a long note is too easy to forget. A grocery list while you are walking through a store. Things to pack before you leave. A short set of steps you need to follow. A URL you want to keep with the rest of your notes. A few tasks that should stay visible today. What you can do with Memo: - Add selected notes to Notification Center - Check frequently viewed notes from the lock screen - Organize notes with tags such as shopping, work, home, or travel - Mark notes as done with strikethrough — completed notes stay visible but dimmed - Share notes as Markdown with tag headings and checkbox support - Customize up to four floating action buttons for quick access to your most-used actions - Save URLs from Safari and other apps with the Share Extension - Import line-by-line lists from a text file - Move finished notes to the archive - Delete notes you no longer need - Create an iCloud backup and restore it when needed Memo is intentionally simple. It is not trying to replace a full notebook, calendar, or project manager. It works best for the small pieces of information you want to see quickly and repeatedly. If you need to write a long document, use a note app. If you need an alarm at a specific time, use a reminder. If you want a short note to stay close at hand, use Memo. Strikethrough lets you mark notes as done without deleting them. A completed shopping item or finished step stays in the list but appears dimmed, so you always know what is left. When you are done, move the checked items to the archive in one step. When you want to share a set of notes, export them as Markdown. Tags become headings, and notes marked with strikethrough are written as [x] checkboxes. Useful for sending a list to someone else or pasting it into another app. Tags help keep the list manageable as your notes grow. You can separate shopping, errands, work, home, travel, and personal notes, then choose only the items that should appear in Notification Center. Finished items can be archived so your active list stays focused, while older notes remain available when you need them. The Share Extension makes it easy to send a URL or text from another app into Memo. When you find a page, product, recipe, or reference you want to check later, save it with a tag and keep moving. Text import is useful for preparing a list on another device or in another app, then bringing it into Memo as individual notes. For small notes that need to stay visible, not buried, keep them on your lock screen and in Notification Center with Memo.
