Is this their first UI??


Holy crap this is practically useless. What should be easy is unintuitive, it took a solid few minutes to even figure out how to use its basic features. Horrid, glitchy user experience - who thought vertical scrolling for feature panes was a good idea? Just, Ugh.

Excellent in every way!

Handwriting Helper

I am adding to my previous comment below because of the other reviews I've read. I believe those users didn't know how to access all the features. Many alternative features are easy to access with a tap on the calendar or cake or with a swipe up or over. It's so easy.... Super Duper, you should show the features on a startup page after someone updates or gets the app. Seems like I should get a cut from this.. You're welcome!
The update for this app is awesome! I can scroll through the dates or I can drop down to quickly change it. I can review old entries. I can view the age quickly and in months. I am so happy about this app now.. OT Testing is already a bear so I don't want to have to think about the little things like this. They do it for you. Awesome App!

Current Update


I have had this app for a while and use it all the time. It has been very helpful during screening time. I loved the old version and how simple it was to enter the birthdate of my student. The updated version is a bit more difficult to enter the birthdate as the year and date are so close together that I sometimes change the date when I am adjusting the year.
