Cost
NZGrapher is free for non-commercial individual use, you can however make a donation.

Schools are required to subscribe. I'm not asking much (50c or $1 per annum, per student, using NZGrapher), this just helps cover my costs for running NZGrapher. Commercial users are also required to pay. Please visit the invoice creator for details.

Any questions about this please get in touch.

By pressing the button below you are acknowledging that NZGrapher uses cookies, and if you acting on behalf of a school, you are agreeing to the costs associated... if you're not happy with this don't use this website. (Privacy Statement)
