“When you're a language teacher, you have to do a thousand things at once. So to manage everything, having an assistant really helps. Well, I see SmartCookie as if it were one :) It helps me plan my classes properly, manage notes, and keep track of students in a smooth and easy way!”

“SmartCookie it's an essential app for teachers because it frees up our time by centralizing planning, student tracking, and assessment, reducing administrative tasks and allowing us to focus on what truly matters as educators: teaching.”
Óscar Ortega

“When I met Martina, I knew she had the best interests of teachers in her heart. That's why I was so excited to learn about SmartCookie. I've interviewed her and was able to test it out - it's a lifesaver for independent teachers who want to focus on growing their business and leave busy work behind. Congrats to the Smart Cookie team!”
