I watched a review of Penbook that convinced me to buy the app, but turns turns out that was on an iOS system. I use a Lenovo, therefore I have the Microsoft version. I have found that there are many differences between these apps and I am wondering why there is not a great colour selection in their Microsoft version of Penbook. Have you guys updated that app recently? I am disappointed with the lack of selection and am wondering if there will be an update on this. I spent good money on this app and am frustrated they’re not the same.
