Awesome
Very helpful!!!!!!!
helped me pass!
used this app consistently for 3 months leading up to my exam and passed the first time! you answer what you can and whatever you get wrong it asks you again at the end of the module, which in my opinion, helped drill things into my head. i passed on my first attempt and i think this app was a big reason why! thank you!

This is one of the most complete apps and worth paying the pro version. Passed the exam on the first try, this app helped me a lot! Thanks!!!
PASSED!!!
The app was great! I used it everyday for about 3 months. I passed the PTCB and now I’m a CPhT. I have already recommended the app to so many people! Keep the great work!
Love this app
I don’t normally write reviews but this app is amazing , I was looking for an app that helps me study and this is the best one. I will be purchasing the pro version. Thank you
