I am very pleased with this app and its ease of use in preparing me for the 608 certification.

I bought the esco training course to help with taking the EPA 608 exam and though it was great and all but still felt like I needed a lot more practice and man this app done exactly that! I can’t stress enough how awesome this app was for actually making everything connect in my head. At first the no pay option was nice but simply paying $3 I got the full access for a week and that was all I needed. I just passed my exam and if I can do it you definitely can too.

Extremely helpful I’ve taken the test once before getting this app and failed. This app has questions that are on the test. Thank u

It is a great app to study for 608 universal

Love it thank you for making this app

Would definitely recommend to any HVAC-R installer/Technician that is practicing for the EPA 608 Test!!

Haven’t tried premium yet but loving it so far.

Truly a great app! Read through the manual once, went through all the questions for all sections here once (core twice), got my universal license on first shot! Great design, great knowledge check and learning.

If you find yourself procrastinating book work but lose hours coding or gaming then this app is the way to binge HVAC Education!
