SlothBox
Letters at a slower pace
Only for iPhone

iPhone
SlothBox is a slower way to write to people you already know.
Make time for a letter. Write to people you know, with delivery measured in days and no read receipts or online status.
You both agree to the correspondence, then exchange text letters that take their time getting there.
LETTERS THAT TAKE THE LONG WAY
After you send a letter, it is picked up in 2–5 hours and delivered 2–5 calendar days after pickup. You can edit your letter until pickup. There is room to get on with your day while it makes its way.
A RHYTHM FOR EACH PERSON
Each correspondence has its own cadence. Keep a different pace with each person you write to.
ROOM TO READ AND REPLY
There are no read receipts or online status indicators. Open a letter, give it your attention, and write back in your own time.
SlothBox is for correspondence between adults who already know one another.
Made for iPhone. Requires iOS 26 or later.
