App is for use by teachers in a classroom, it allows the use of a seating chart to take attendance, keep track of whether homework was handed in, and take fire drill attendance. Also, it randomly creates groups of students and picks students at random. The featureset in this app was specifically requested, initially, by a High School Teacher in the family (so yes, this is one of those things I wrote for personal needs, but others can access it). It's on Google Play and Apple App Store, written in Java/Kotlin for Android, and Swift for IPadOS. Use the app title link text above to get to downloads page.

I wrote this Very basic POP3 e-mail (using "metro" for windows) app in C# because Windows 8 did not include POP3 support in the Windows Mail app. Basically, i needed to be able to access an account so i created the app. The app, fmail for windows store, was on Windows 8 App Store, when Windows 10 came out POP3 support was once again included in mail app so this app was no longer necessary. The reviews for this app weren't too good, but I really wrote it for my own needs and 'let' other people buy it (I earned maybe a couple thousand dollars when it was for sale, which was perfect because I had income limitations on disability insurance.)
