Wet-Dry-Try Handwriting 4+

I bought this app several years ago and although it is more picky (requires better precision) and not as easy to use for the students, it was still was a nice option for letter and number tracing. I like that it uses the correct verbal cues for formation. However, now I need to re-purchase the app because they changed the platform. It is the exact same app with no new items or improvements. At least if they want you to re-purchase something, it should offer something more. I do not plan on buying it again, because there is nothing new and there are a lot of other apps that work well if not better. I’m a big hand writing without tears supporter, I will just use their workbooks and manipulatives like the slate board.
Now a year later... I bought the app again and I couldn’t even use it really. I am a busy OT and basically like to pick and choose the magic c and diver down letters, or any letters students are having trouble with. They are all locked and need to be unlocked and go in order. Now I am not going to re-purchase until they fix all their issues.

I like handwriting without tears but this app needs improvement. The idea is fine but even with the sensitivity level set on the easiest, sometimes even I can’t get the app to approve my letters after multiple tries. It’s way too frustrating for my child when he’s doing a good job but the app keeps telling him he’s going off the board or whatever.
I thought it would be a good alternative to a real wet dry try board but I will go with an actual slate unless the app is updated and improved more.

I’ve been trying to create an account for 15 minutes. Every time I enter my credentials, it says “something went wrong” but doesn’t specify what the issue is. How is anyone supposed to use this app?
