Wow! Thanks for the vote of confidence.

Best Step 2 supplement

Wish I found this app sooner during 3rd year and only finding this now during dedicated. After doing UW I get so exhausted but this app makes studying so effortless and fun. Highly highly recommend! Super helpful!

Thank you!!

Nice

Great app and it helps me get the high yield info but is there a user manual or guide somewhere? I’d like to figure out if I’m using the app right

Great app

I love this app. I use it to test my memory. My only complaint is I wish I could disable the timer. It goes off every 2 minutes and ends the test which can be annoying

Response from developer

Thanks for the feedback and you’re right. The timer in rapid review is quite annoying. I redesigned the interface so the ck gold section comes up first and that doesn’t have the timer. I’ll also take out the rapid review timer.
