DigiLoveLetter

DigiLoveLetter lets you write a digital love letter in one of nine templates, seal it, and send a private link or QR code. The recipient opens the link in any browser, taps the seal, and the letter unfolds, with optional photos (up to ten), a song from the built-in music library, and a voice note. You can set a timed unlock and a custom link. It is free, with no sign-up for the writer or the recipient.
