Purchased moduals prior to the app update, spent about $60+ on all water treatment. After the update, i am now being forced to spend another $60+ for the same modules on a subscription basis AND the questions don't even rotate. They're all the same. I hate the new update. If I've already paid for full access why should I be forced to pay for it again.

Wanted to try the "free trial" to see if this app could help me with my upcoming WD level 3&4 tests but right away it wants to charge me through my Google account. They also only have 6 month or 1 year subs starting at $45. I would be more inclined to subscribe at 1 month for $7.50. I also emailed their support about this issue & got no reply. This app is not worth it. Don't waste your time.

To be clear, I passed my 3's.. But, this app is only vaguely relevant to the tests I took which were the water distribution and collections 3. I had completely memerized the advanced questions and most of the intro questions. Then when test time comes... MAYBE 3 questions on the test are VAGUELY relevant to what I studied. Id say youre better off reading the book. But, I couldn't tell you which, being that there were a significant number of treatment questions on the test too. Good Luck.
