Ememo

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/
