There are a lot of books out there focused on ACT prep, but none compare to this app! What the books lack are refreshers of the basic material needed to solve the more difficult problems and THOROUGH explanations on how to solve. The videos make a huge difference; it's just like being in the classroom. The progression of the material (basic-advanced) is perfect and feels very natural. I can't say enough good things about this app, it is worth much more than $40!
This is a great app that has significantly improved my confidence going into the ACT exam. I haven't taken a standardized test in over 12 years and this app has been great in rekindling the math equations I will need to be prepared for. I will keep my eye out for this developer's apps going forward. I hope they will also make a GRE prep (unless they have already), it would definitely be worth my money!
I haven't been through everything but what I have I liked. As a tutor it is always nice to have tons of worked examples. Not a big fan of the slow pacing videos but since I'll be around to teach I don't see that as much of an issue. Nicely done, now here's hoping all the math is correct :)
Terrible midnight purchase. The videos are very uninformative while tending to crash before getting halfway through. The ads are miserable as well. $10 app with nonstop stream of certified iAds to pinch a little more change from us is ridiculous.
