We're glad you're excited about using Cambly! Although we wish we could help everyone, unfortunately, Cambly is a paid service, so you do need to subscribe to a monthly plan to continue practicing. This is because we need to pay our tutors in order to retain such a high level of quality in our teaching. To subscribe to a daily plan, go here: https://www.cambly.com/en/subscribe
We hope to see you on Cambly soon!
