I've recommended it to friends. ### 5/5 — Love it!!!!!! *2017-02-24, version 3.22.1* ❤️❤️ ### 5/5 — It's FREE!! *2017-01-29, version 3.22.1* Great app with many questions and explanations. Best of all, it's all FREE! ### 5/5 — Absolutely Wonderful ! *2016-12-07, version 3.19.1* It's easy to use and straight to the point. It tells you facts about the test and even tell you how long you need to take on each question to finish on time. I'm currently a 7th grader ... so the explanations help me a lot. This app is truly wonderful! ### 5/5 — Great app *2016-11-11, version 3.18.4* Very useful!! ## Most critical reviews (10 lowest-rated) ### 1/5 — Bad *2016-09-30, version 3.18.4* App won't even load so there's no point in having it ### 3/5 — Helps, but often confusing *2017-05-22, version 3.24.2* This app has definitely helped me to figure out what I need to study before taking my ACT, but way too often am I missing questions because the wording of the question is confusing. For example, a question asked for the length of a fence that would be 135 feet by 195 feet. You would obviously think it is a vocabulary based question and answer with 195, but the questions correct answer was 660. Apparently the "length" actually meant the perimeter, and that wasn't the only question that's been confusing. ### 3/5 — Good App Overall *2016-03-18, version 3.14.5* A good app for studying and improving for the ACT, however the pro version seems a little pricy. The restrictions that are set upon only downloading the free version brings my ratings down for the app. Maybe a little more opportunities and subjects to study for would've earned 5 stars. ### 4/5 — Not bad *2018-08-21, version 3.24.2* Didn’t really study for my ACT, but a lot of the prep I did do was via this app. Quality content, good organization. If only the SAT did stuff like this for mobile ### 4/5 — Really helpful! *2017-04-09, version 3.24.2* So far I'm very happy with this app as far as I can see it's helping me a lot with studying. I love how I can rate the questions on what I know so I'll be able to go back and do those again until I figure them out. The only suggestion I'd make is for a timer so that I can better figure out my pacing, it's just a hassle to set up other timers, not that I can't do it but that is the only thing I'd change at the moment. Thanks for this helpful app! ### 4/5 — Pretty good *2016-01-22, version 3.12.3* Some of the questions have mistakes in their references.. One question on the math question asked what P was when instead they were asking for A and there was no P ### 4/5 — Great app! *2015-10-08, version 3.12* Very useful. ### 4/5 — Great App *2015-08-27, version 3.11* Besides the occasional not getting it to load, the app is great. As a senior I only have so much time to get on and get things accomplished anyways. So whenever I'm in the car, or out of computer access it's great to be able to study for the ACT. ### 4/5 — great *2015-08-26, version 3.11* great app, really helps ### 4/5 — Pretty good *2015-08-26, version 3.11* Just wish it was all unlocked.! ## Most praised reviews (10 highest-rated) ### 5/5 — Awesome *2020-06-02, version 3.24.2* This is truly amazing ### 5/5 — Best option *2020-02-14* Best ACT app I could find for free ### 5/5 — AMAZING!!! *2019-02-09, version 3.24.2* This app allowed me to study whenever and wherever I pleased. I strongly believe that it positively impacted my overall score. HIGLY RECCOMEND! ### 5/5 — My opinion *2018-12-07, version 3.24.2* It’s very helpful and actually give explanations when your answer is incorrect and it explains why the other answer chooses are incorrect. It’s a very good app. ### 5/5 — Helpful! It’s a really solid app. *2018-07-25, version 3.24.2* So the app is really nice. They split everything into main groups from math, science, reading, writing etc. And then they have sub groups within the section you pick. You can see your accuracy and how much time you spend on q’s and what you need to improve on.. it’s pretty solid. I haven’t had problems. :) ### 5/5 — Great App! *2018-06-27, version 3.24.2* Very helpful in providing thoughtful questions and explanations. User compatible and well rounded. Would like for it to be updated to see what else it could offer! :) ### 5/5 — Must have for ACT Practice!!! *2017-12-04, version 3.24.2* Very helpful and fast paced to stimulate time limits on actual test. Highly recommended if you need some extra ACT help. Presents one question at a time and multiple choice answers. ⭐️⭐️⭐️⭐️⭐️👍🏼 ### 5/5 — 5stars beba *2017-08-18, version 3.24.2* Great app!
