Some information only matters for a little while: where you parked, the hotel WiβFi password, a number to call back, a coat-check ticket. TimeGlass keeps it close when you need it, then automatically removes it when you donβt. A LIFETIME FOR EVERY NOTE Choose 1 hour, 1 day, 1 week, or 1 month when adding a note or photo. When time runs out, it disappears automatically. No more notes piling up long after theyβve stopped being useful. RENEW WITH A SWIPE Still useful? Swipe right to restart the countdown. Touch and hold to change its lifetime, share, or delete. Items nearing expiry are marked with an βExpires soonβ badge. PHOTOS TOO Capture a parking sign, receipt, or ticket directly in TimeGlass, or choose an image from your library. Open it full screen and pinch to zoom. SCAN AND KEEP PDFS Scan multi-page documents with the camera or import PDFs from Files. Preview and share the original file. Documents sync through your private iCloud account and disappear after the duration you choose. OPTIONAL REMINDERS Enable notifications for a heads-up before expiry: 10 minutes before a 1-hour item, 1 hour before a 1-day item, and 1 day before a 1-week or 1-month item. ON ALL YOUR DEVICES Your notes and photos sync through your private iCloud account between iPhone and iPad, and remain available offline. β’ Home Screen widget: start a note or open the camera with one tap β’ iPad: drag and drop text, links, and images from other apps in a two-column layout β’ Apple Watch: dictate or type a note; it reaches your iPhone even when the phone is temporarily out of range PRIVATE BY DESIGN No account, no ads, no tracking. Your data stays in your own iCloud and is never collected. TimeGlass is available in English, French, German, Spanish, Italian, Brazilian Portuguese, Japanese, and Simplified Chinese.
