About

Memory

Features
Read full description

Memory is a planner for university students, laid out like a newspaper: what is due, when, and nothing else. Write a reminder the way you would say it. Type "problem set 4 CALC tomorrow 5pm" and Memory reads the course, the day and the time straight out of the sentence. THE DAY, ON ONE PAGE Today opens on what is overdue, what is due before midnight, and what is waiting later in the week. Anything you have been carrying says how long you have been carrying it — two days late, two weeks late — because a number is harder to ignore than a red dot. YOUR WEEK, PRINTED Put your classes in once and your timetable is set: every session, every room, each course in its own color. The class bell tells you before one starts, so the timetable is something you read on Sunday, not something you check between buildings. REMINDERS THAT DO NOT NAG Gentle nudges send one notification and never repeat, and each reminder picks its own warning: at the time it is due, or five minutes, an hour or a whole day ahead. An exam wants the day before. A problem set wants ten minutes. Morning edition sends a single summary at eight, and then leaves you alone. Sound is off unless you turn it on. Have both, one, or neither. THE MONTH AT A GLANCE A calendar that fits the whole month on the screen, with the days that carry something marked. Useful the week you are deciding whether to take on more. ALSO INSIDE Repeating reminders, daily or weekly, with an end date. Courses with their own colors. Search across everything you have written. A dark edition that follows your phone. Airy or compact spacing, whichever you read better. Your work follows you from one device to the next. LOOK BEFORE YOU SIGN UP Tap "Look around first" on the opening screen. Memory fills itself with a sample semester and every screen works — tick things off, write new ones, browse the month. Nothing is saved and no account is made. QUIET BY DESIGN No ads. No trackers. No analytics, and no crash reporting — none of it is in the app to begin with. Sign in with a one-time code sent to your email, with Apple, or with Google. Delete your account, and everything in it, from inside the app. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
