The honest answers.
Can I cancel?
Any time, from your dashboard, and you keep Pro until the period you already paid for runs out. No email, no phone call, no retention script.
Does it work on my phone?
One account covers the website and the apps. Study on the bus, review on the unit, and your progress is the same everywhere. It lives on the account, not the device.
I haven't set an exam date yet.
You don't need one. Without a date the daily lesson is 10 questions built from what you are weakest on. Set a date later and it grows on its own as the date gets closer.
What happens to my progress if I stop paying?
Nothing is deleted. Your streak, your history and everything you have mastered are still there if you come back, and the free tier keeps working.
Is this enough on its own?
It is the instrument and setup half, done properly: 193 trays and 2,759 instruments, tested until you are quick with them. It is not a full CST review course and does not pretend to be one.
Stop guessing what's on the tray.
Every setup, every instrument, and a study system that knows what you're about to forget. Ten minutes a day until it's boring.
