Handwriting practice for children who are just learning to write.
Print, cursive and numbers, traced with a finger or an Apple Pencil on four ruled lines. Built for one five-year-old and her younger brother, and then built properly.
Printing, joined cursive and the numerals — each with its own ruled paper, its own stroke order, and its own spoken instructions.
A letter is right when it is made right. Letterling follows where the pen starts, which way it travels and whether it stays on the line, and says something useful when it doesn't.
The first word a child writes is the one they care about. Letterling asks their name on the very first run and starts there.
Every setting, every sticker and every scrap of progress belongs to one child. A younger sibling can't undo an older one's work.
A lock in front of the settings, a daily time limit, and a confirmation in front of anything that would erase something.
Letterling has no server, no account and no network code. It works on a plane, in a car, and in a house with the Wi-Fi switched off.
The cursive is Hershey Script, a stroke font drawn by Dr A. V. Hershey at the U.S. National Bureau of Standards in the 1960s. It is not an outline font. Each letter in it is a pen path — open, ordered, with a start and an end — which is exactly what a child needs to follow and what an ordinary font cannot give.
So nothing in the alphabet is traced from a picture or guessed at. The line a child follows is the line Hershey drew, measured and placed on this app's ruling.
Letterling collects nothing. It has no servers, no accounts, no analytics and no advertising, and it never opens a network connection. A child's name and progress are stored on that device and nowhere else.
