FAQ
Questions teachers ask
Do my students need to pay or sign up?
No. Students join free with your class PIN and their first name. Only you need an account.
What happens after the free trial?
Pay ₦5,000 for a month at a time. Any trial days you have left are added on top. We never store your card or charge you automatically — we email you before your month ends, and you renew only if you want to.
How do I pay?
Securely through Paystack — card, bank transfer or USSD.
Does it work in a physical classroom?
Yes. Put the board on a projector or smart TV, or share your screen in Zoom, Google Meet or WhatsApp. Students can follow on their phones either way.
Will it work on cheap phones and slow data?
Students only need a web browser. The board sends drawing as small updates rather than video, and slides are compressed for mobile data.
How many students can join one class?
Up to 300.
