Just Remember helps you hide, recall and check content you prepare yourself. It continues Kakushi’s photo masking features and adds text-pair study sets. CREATE FROM PHOTOS Take a photo or import a page from your library. Cover what you want to remember with freehand strokes, rectangles or lines. Tap masks individually, reveal them all or hide them again. Organize photo sheets and text sets in folders, number questions, optionally save correct answers and enter responses, and set review reminders. CREATE TEXT PAIRS Enter the front and back side by side in two columns. Start with ten rows and add ten more whenever you need them. Use words and meanings, terms and explanations, dates and events, or your own multiline content. Edit, delete and reorder pairs. RECALL, THEN CHECK Before starting a text-pair session, choose list or single view, the side to show, and original or shuffled order. Study then opens full screen; reveal answers as needed. Shuffling never changes the saved order, and opening an answer does not mark it correct or mastered. REVIEW RECORDS Folders can hold photo sheets and text sets. A simple record shows the unique answers you opened and when you last reviewed each material. STUDY SAVED MATERIALS OFFLINE Once a photo sheet or text set is saved inside the app, study it without Wi-Fi or mobile data. Revisit your own materials on the train or whenever you have a moment to practice. FREE AND PRO Create up to five new photo sheets per month for free. Keep up to three text sets, with unlimited pairs in each. Saved materials remain available to study and edit, even when you are over the free limit. Pro provides unlimited photo sheets and text sets, with no ads. The existing monthly subscription and one-time lifetime purchase remain available. Existing Pro purchase rights are retained. Purchasing and restoring purchases may require a connection.
