Hi! Yesterdays is a simple, privacy-centric memory tracker. Use it to write down and remember those sayings, thoughts, or feelings you might otherwise forget. - Private by Design: All your data is either stored on device or in a private iCloud container if you've got an Apple ID. - Simple: No bloat. Fast. Just write and remember. - Synced Automatically: No account creation needed. If you're signed in with the same Apple ID on multiple iOS devices, everything will just sync. - Photos & Audio: add them to your memories, or don't! The choice is yours. - Face ID / Touch ID: add some extra protection from prying eyes. - Randomized Nostalgia Trip: At the press of a button, view five random memories from your collection. - Widget: Show a random memory on your home screen, shuffled every so often. - Writing Reminders: get nudged to jot down a memory every week (ish). - Tags: Tag your memories to find them easily later and easily keep track of people, ages, dates, or themes - Import: Bring your previous memories with you via CSV import. Share text, photos, or audio into Yesterdays via the system share sheet. - Export anytime: Take your memories with you in the form of a very compatible .csv file. Individually share memory text, photos, or audio as well. - Premium users can customize the font and app icon. Give it a try and store 10 memories for free. Want to store more? Subscribe to Yesterdays Premium for a low yearly cost. All memories are accessible even if you unsubscribe later on. We take privacy seriously. Really. We don't track anything about you.
