Try the EasyKOT register — free, no signup.

Open easykot.com/demo on a laptop or desktop and the real register is live in seconds. It's the till that runs at your counter, so it wants a laptop-size screen — on a phone there is nothing worth showing you yet.

• Punch an order off a real 212-dish menu — Mezbaan, a sample restaurant.
• Fire the KOT, then a second round that sends the kitchen only the new lines.
• Settle in cash or UPI and read the GST bill that comes out the other side.
• It all runs on your own device — offline, and nothing you type reaches us.

On a phone right now? There is a phone way to run a restaurant too — an Android phone + thermal printer runs the whole restaurant.
