When I handwrite a 7, it has a dash through the middle. Everyone I know does this. Your app doesn't like these; it sees a 3.

Really?? It is the opposite here. No one really uses the dash. I like wee differences like this.

I wrote it without the dash for most of my childhood, until I found out the dash was a possible way to write it. From then on, nobody ever mistook my 7's for 1's anymore. It was great, since I have really bad handwriting and I'd take all the help I could get not to get things wrong on tests. Zeroes get slashes, too, just for safety.

Who is no one? Where is here?

In my experience the dash is unusual (but not unheard of) in the US. I've heard people refer to it as a German or European 7. I've never seen the German 1 that is like an upside down V used by an American.

I just tried a few 7s with dashes and it got them all, how big a dash do you use?

Just tried it with my usual length dash (extending 3/4 along the top line to the left, and about 1/4 out the other side) and it returned a 3. Used a smaller dash and it returned a 7. Exceptionally neat tool though and seriously impressive!

I use a dash too, but it recognises it OK for me

And when I handwrite a 1 with a serif at the top, it sees it as a 7

For me, it returns a 2.

I would just assume you wrote a 7, realised it was wrong, and crossed it out.

But yes, the recognition isn't 100% accurate. There are quite a few simple "0" shapes that it doesn't get right.
