Like showing a parent what their child's vision is like." - Optometrist "This would be extremely helpful! I have parents all the time asking me to describe what their kids see." - Optometrist "The colorblind filters are genius for helping me decide what colors to choose when trying to make things more accessible." - Board game designer "This is amazing! I'll probably be using it every day!" - Optometrist Whether you're an eye care professional explaining a diagnosis, a teacher building empathy in your classroom, a parent understanding your child's vision, or just someone curious about the world, What They See lets you step into someone else's perspective.

ClassTrack

Read full description

ClassTrack is a behaviour log for teachers, built for the thirty seconds you actually have. Swipe a student right for positive or left for negative and the sheet opens with half the decision already made. Tap what happened, and get back to the lesson. By the time the parent meeting comes around, a term of small notes has already become a report. Everything stays on your device. No account, no sign-up, no cloud, and no advertising for anyone, free or paid. Student names and behaviour records never leave the device they were typed on — which is what makes ClassTrack easy to put in front of a principal or a privacy officer. LOG IT IN SECONDS • Swipe or tap a student, pick a behaviour, done • Log the whole class at once when everyone earned it • Positive and negative behaviours, grouped by category • Add a note by typing or by voice • Works entirely offline — a dead Wi-Fi day changes nothing SEE WHAT IS ACTUALLY HAPPENING • Class and per-student summaries • Behaviour trends over the term • Category breakdowns — is it the work, or is it the time of day? • Recent activity at a glance WALK INTO THE MEETING READY • Export a PDF report for one student or the whole class • Pick the date range: a week, a term, the year • Plain enough to hand to a parent, specific enough for an IEP meeting or a referral YOUR DATA, AND YOUR BACKUP • Back up and restore whenever you like • Automatic backups on a schedule you set • Free, deliberately and permanently — your records are not a hostage FREE, WITH NO ADS Unlimited classes, unlimited students, unlimited behaviour logs, PDF exports and backups. Not a trial, and not capped at one class. CLASSTRACK PLUS • Behaviour heatmaps — which days and times behaviours cluster, per class and per student • Charts in your PDF reports — category breakdowns, top behaviours, trends over time • Your school logo on exported reports, and no upgrade footer • Your own behaviour list — rename, add and organize the behaviours and categories your classroom actually uses Plus is available monthly or annually; the annual plan works out to about half the monthly price. Prices are shown in your own currency before anything is charged. FOR SCHOOLS AND BOARDS ClassTrack can be licensed for a whole staff, priced per teacher per year. Because student data never leaves the teacher's device, there is no data-sharing agreement to negotiate. Email info@joshuamakes.ca.
