The Prime Machine vs Present

The Prime Machine is a corpus tool, providing access to readymade English language corpora and tools for analysis of your own DIY corpora made from text, PDF, or other document files. In Simple Mode, you can view concordance lines as lines or cards, frequency data and collocations. In Full Mode you can view additional data from the readymade corpora, use more research tools and create your own DIY corpora.

One roster. Take attendance in seconds, and call on people fairly. Present is for teachers, coaches, club leaders — anyone who has to find out who's here. Only you need the app. Nobody has to sign up, install anything, or scan a code. ■ Attendance in seconds, three ways · Grid: everyone starts unmarked. Tap a name to sign someone in and their tile drops to the bottom — whoever is left at the top is absent. Nearly a full house? Tap "Mark all present" and pull out the few who didn't show. Forty students, a few seconds. · One by one: a big card per person. Swipe right for present, left for absent. Good when you need to look up and check faces. · Seats: your real seating chart. An empty desk is obvious at a glance. ■ Fix it afterwards Someone walked in ten minutes late? Tapped the wrong name? Open that session and change it. Every amendment keeps the original — what it was, when you changed it — and you can undo it anytime. Attendance rates recalculate immediately. ■ Photos for the faces you don't know yet Add a photo to any member and take the roll by face. Worth its weight when you're substituting, taking on a new class, or running a camp. ■ Fair random picks Cold-calling shouldn't always land on the same person. Turn on Fair mode and people who have been picked less come up more often. You can also stop repeats within a round, or reset the counts and start over. ■ Several sessions a day, kept straight Tag each one — Morning, Assembly, 3rd period. Take the roll three times in one day and the history stays readable. ■ Numbers you can trust Attendance rate, most absences, per-session detail — all computed from the actual records, never a number someone typed in. Who has been missing lately is right there. ■ Share it or export it Generate a clean summary card — all time, this month, or this week — and send it to a parent or a group chat. Need a real spreadsheet? Export CSV: every member by every session, opens in Excel without mangling anything. ■ iPhone and iPad Roster on the left, detail on the right on iPad; a single column on iPhone. Use the iPad at the front of the room and your phone in the hallway — same data. ■ Your data is yours Everything lives in your own private iCloud and syncs between your devices. We can't see it, and we don't collect it — no account, no ads, no third-party tracking. Classrooms · lectures · tutoring · clubs · sports teams · meetings · camps Questions or ideas? We'd love to hear from you.
