Read full description

Remember everything, store information, and get reminders for important notes automatically - just type your notes in natural language, and the app does the rest. Mnemosyne: Mind's Archive offers a minimal, private note-taking experience. Like in the good old days of feature phones, the app focuses only on its core feature - no additional bells and whistles. Enjoy note taking in its purest form. Take your notes completely offline. The app doesn't use any internet connection, so all your notes and reminders are exclusively yours, stored locally on your device. Automatic reminders let you simply write your note - if you mention a date or a time, a reminder will automatically be added. View all your notes and reminders in a single app. PRIVATE NOTE TAKING Your notes are stored only on your device - no syncing involved. You are the sole owner of your data. ORGANIZE YOUR NOTES Use the Groups feature to organize your notes. Create as many groups as you need and choose a group to add notes to. Every new note is saved into the selected group. Set default advanced reminder times for each group - for example, one hour in advance for emails and one day in advance for events. The choice is yours. AUTOMATIC REMINDERS Type a note in natural language and when you mention a date or time, the app will create a reminder for you. Write sentences like: "Lunch with Adam at 5 on Monday" or "Take the car to maintenance service next Wednesday." Dates and times will be highlighted in a different color, and you will receive an auto-reminder popup. REMINDERS CALENDAR View all your scheduled automatic reminders in a calendar. Click on a date to see all reminders for that day. Swipe the calendar to change months and years. Swipe individual reminders to mark them as completed or remove them. Completed or removed reminders will not trigger a notification. MINIMAL FOCUSED EXPERIENCE Focus only on what matters. The app will not overwhelm you with features - it simply takes notes and reminds you about them, allowing you to use your brain to enjoy the moment. NOTIFICATIONS The app will request your permission to send notifications, with the intent of alerting you about upcoming reminders. Choose whether you want to be notified - the control is in your hands.

About

Most task apps hand you a long list and let you stare at it. Sammy hands you one card. Swipe right to start it, swipe left to skip it. That's the whole thing. WHY ONE CARD INSTEAD OF A LIST A to-do list asks you to do three things at once: choose what matters, rank it against everything else, and start. If you stall at the starting line, that isn't one wall, it's three. A single card collapses all of it into one binary decision: this task, yes or no. That's a decision size a stalled brain can actually make. HOW IT WORKS - One task at a time, never a wall of to-dos - Swipe right: a timer starts, you begin - Swipe left: skipped, no penalty, no judgment - Sammy the squirrel collects a nut for every task you finish, visible progress right now instead of some abstract payoff later - Decks for chores, admin, self-care, getting out the door, and days where brushing your teeth is the whole win NO STREAKS, NO GUILT Sammy doesn't count how many days in a row you've kept it up. There's nothing to break. Anyone who has fought procrastination knows the spiral: miss one day, and the app becomes one more thing accusing you. Sammy only counts upward. WHO IT'S FOR People with ADHD, executive dysfunction, anxiety, or just an ordinary bad day. Adults, teens, and kids, with content curated per age group. HONEST ABOUT THE SCIENCE There's a screen inside the app that explains the actual mechanism behind each feature: why task paralysis is better understood as an activation failure than a motivation problem, why decision fatigue costs more for ADHD brains, and what the nut counter is really standing in for. It's equally explicit about where the evidence is thin: there is no controlled trial of Sammy's specific implementation. That's exactly why there's a free trial instead of a "trust us" pitch. PREMIUM - Unlimited custom decks and cards - Mood check-in: tasks adapt to your actual energy, not the energy you wish for - Full win log - Recurring schedules - Two more companions: Eddy the elephant and Tammy the turtle - Offline decks Sammy is not a medical device and does not replace diagnosis, advice, or treatment.
