PRIVACY FIRST. YOUR CONTENT STAYS ON YOUR DEVICE Your photos, notes, and the information inside them stay on your device. Latermark is designed around privacy from the start. Photos are processed directly on your device, including the text used to make them searchable. Your saved content isn't uploaded to a server or sent to the cloud. What you save stays yours. SAVE WHAT MATTERS. REMEMBER IT LATER. Your photo library wasn't designed to hold every receipt, document, reminder, and random thing you might need someday. Save a photo, document, receipt, place, idea, or quick text note. Add context if you want, choose whether it should remind you later, and move on. Latermark gives the things you may need again a place of their own — without turning your gallery or notes app into a dumping ground. FIND WHAT'S INSIDE YOUR PHOTOS Sometimes you remember the information, but not where you saved it. Latermark can recognize text inside your saved photos directly on your device. That means you can find an image even when the word you're searching for was never written in the note. Saved several receipts? Search for a word printed on one of them. Looking for a document with a specific number? Search for the number. Can't remember which photo contained the information? Just search. No manual sorting required. REMIND YOURSELF ONCE — OR AGAIN Some things only matter later. Save a photo or write a quick note, then choose when Latermark should bring it back to you. A bill to pay. A return to send. A document to submit. An appointment you can't miss. Something you need to follow up on. Create a one-time reminder or make it repeat when needed. Latermark remembers so you don't have to. TEMPORARY NOTES THAT DON'T PILE UP Not everything deserves a permanent place in your notes. For things you only need to remember once, Latermark can automatically delete the note after reminding you. Create it. Get reminded. Let it go. Your temporary reminders don't have to become permanent clutter. SAVE IT YOUR WAY Take a new photo, choose one from your library, or create a text note without attaching an image. Keep the original photo when you need it, add a note for context, and decide whether you want to be reminded later. You can also create notes with Siri when you need to save something quickly. RIGHT THERE WHEN YOU NEED IT Keep upcoming reminders visible with the Home Screen widget and receive notifications at the time you choose. Customize Latermark with the color you prefer and make it feel like your own. A QUIETER WAY TO REMEMBER Latermark isn't another app asking for your attention. It's there when something matters, reminds you when the time comes, and stays out of the way when it doesn't. Save what matters. Remember less.
