Tap to talk, tap again, and it’s written down. Memo Keeper turns what you say into a note and reminds you right on time. Your notes live on your iPhone, not on our servers: no account, no ads, no subscription. Type “Pay rent tomorrow at 3pm” and it offers to set the reminder. Take notes from the Lock Screen, Home Screen, Control Center or Siri, and open the app to see Today: everything to remember today, in one place. TAP TO TALK Tap to start, tap again to save, or hold if you prefer. What you say is turned into text right on your iPhone, and the original recording stays on your iPhone so you can play it back. Free: up to 1 minute per note. Pro: 5 minutes at a time. HANDWRITING, PHOTOS AND DICTATION Write with your finger, or snap a whiteboard, a receipt or a screenshot: the text is recognized on your iPhone, so search finds it. While editing, tap the mic above the keyboard and your words appear at the cursor, with line breaks, punctuation and formatting as you go. REMINDERS THAT MATCH HOW MUCH IT MATTERS A Normal reminder is a notification. Important ones come through even in Focus. Alarm reminders ring full screen like an alarm clock on iOS 26, even on silent, with a 10-minute snooze. With Pro, turn on Until Done: stopping the alarm doesn’t count as done, so it rings again a few minutes later, up to 3 more times, and stops as soon as you tap Done. Pick its sound, or record your own voice. PICKUP CODES, WITHOUT DIGGING THROUGH MESSAGES Copy a message with a pickup code, or share a screenshot, and the code lands in Today and on your widgets. Set up a Messages automation in Shortcuts once, and codes from new texts are saved as they arrive, without opening the app. With Pro it also goes on the Lock Screen and in the Dynamic Island, and one tap clears it once you’ve picked it up. CALENDAR, RECORDINGS AND THEMES (PRO) Tap Calendar next to Today to see how many things you have each day, and add the Calendar widget. Share a Voice Memo or a meeting recording to Memo Keeper and it becomes text on your iPhone, even an hour-long one (iOS 26). Pick one of five color themes, with matching app icons. NOTHING GETS LOST The copy on your iPhone is the original. Deleted notes stay in the Trash for 90 days, every note keeps its versions, and a snapshot of all your notes is taken daily. iCloud Backup stays off until you turn it on, and even then iCloud only holds a copy: if iCloud fills up or you switch accounts, you won’t lose a single note on your iPhone. BRING YOUR APPLE NOTES Export your Apple Notes as Markdown on a Mac with macOS 26 and bring them all over at once, or share them in one by one. Your originals stay untouched. PRIVATE FOLDERS Keep passwords, IDs and diaries in a private folder. Its notes are stored encrypted and open with Face ID or your passcode. With iCloud Keychain on, they open on your new iPhone too, and there’s a printable recovery code just in case. NOTES THAT LOOK GOOD AND TRAVEL WELL Headings, bold, highlights, text colors, lists and dividers are a tap away in Format. Paste Markdown from an AI chat and it turns into formatting. Share a note as a long image, or save it as an A4 PDF. WHAT MEMO KEEPER DOESN’T DO No account to sign up for. No servers of our own: we can’t see what you write. No ads. No subscription: pay once and it’s yours. WHAT’S FREE Notes, handwriting, images, search, reminders, iCloud Backup, the Trash, version history, daily snapshots and Export All, plus up to 3 Alarm reminders at a time, 1 private folder and long images on white paper. WHAT PRO ADDS, ONE-TIME PURCHASE Each day’s details in the Calendar, Transcribe a Recording, themes and app icons, Until Done alarms with your choice of sound or your own voice, unlimited Alarm reminders, pickup codes on the Lock Screen and in the Dynamic Island, widgets that show everything, 5 minutes per recording, paper colors and PDF for long images, and unlimited private folders. Say it once. Memo Keeper remembers.
