You save a link "for later." Later never comes. Back to This fixes that. Instead of dumping links into a bookmark folder you'll never open again, Back to This reminds you — again and again — until you actually open the link or delete it. It's a link inbox with a nudge, not a graveyard. THE 15 RULE Your inbox holds up to 15 active links. Save a 16th and the oldest quietly moves to your Archive. A short, finishable list instead of an endless pile — because if everything is saved, nothing is. HOW IT WORKS • Paste or share a link from any app • Tag WHY you saved it — Read Later, Learn, Work, Idea, Buy, Watch, Reference • Pick WHEN and HOW OFTEN to be reminded • Get repeated reminders until you open it or let it go BUILT TO BE FAST • Save from any app with the Share extension • Tap a reminder to jump straight to the link • Open in the related app, or read inside the app • Clean, distraction-free, light and simple WHY PEOPLE LOVE IT • No feeds, no ads, no social clutter • No account required — your links stay on your device • Reminders that don't let you forget • A calm inbox that stays small on purpose Stop bookmarking things into the void. Save it, and let Back to This bring you back. — Back to This Pro Try everything free for 7 days. After the trial, keep Pro for the listed price per month.
