### 3/5 — Great Info, bad app functioning

*2026-03-25*

I love and hate this app. It has helped me tremendously with information that I need to know of the PPL check ride, and just for general knowledge… but the app barely works! I only have a MacBook and I can’t turn the pages in the answer manuals unless I manually click and drag my finger, and it is so sensitive that it flips me 10 pages at a time. Neither the “turn page” button at the top, nor the left and right keys on my MacBook let me turn pages. 

I downloaded it on my phone and can turn the pages on there, but it is so much better visually on the Mac. I hope they fix this because then I would recommend to everyone getting their PPL or any other license!

### 5/5 — Great Resource

*2026-03-24*

Great resource that goes through every bit of the ACS for private, Instrument, and Commercial. If read through and study the material in this app, almost guaranteed to pass the oral exam

### 5/5 — Best way to study towards piloting certifications.

*2026-02-27*

I was in charge of enrollment at a flight school in WA state and recommended this app to any new student pilot who enrolled.

The app is organized in a way to let you study with ease, and the information is very much in depth. This goes above the standards you will need to pass a practical and oral test. So if you study using this, you will have no issue on the big day.

### 5/5 — Used for PPL written

*2026-02-27*

Loaded with tons of information, the videos are concise and thorough. The ACS is broken down through the videos and easy to follow along. Helped me pass, good luck!

### 5/5 — No Brainer

*2026-01-21*

I have never left a review for an app in my life. I’m studying for my private pilot checkride. I’ve purchased a lot of aviation study materials thus far. This is by far an absolute necessity of an investment for your checkride. Don’t hesitate and just take my word. I even had a question on the best ways to use the app to study, and the developer reached out almost immediately and went above and beyond in answering my question,and even gave more tips and advice.

### 5/5 — The Most Comprehensive & Straightforward Resource for Studying the ACS

*2025-12-12*

Wow! A word to the team - I just wanted to say thank you for all the work you’ve put in to ATTACS! I stumbled across it while studying for Commercial and found it to be the most comprehensive, yet straightforward, resource for studying for and alongside the ACS.
I have aspirations of becoming a flight educator and intend to recommend use of your products to my future students.
Thanks again!

**Developer response:** Thank you! My goal is to help you feel truly prepared and keep it at a great value. I’m glad that was the case for you and I truly appreciate the review and recommendation.

### 5/5 — Great Tool!

*2025-08-10*

Looking at getting my pilot’s license and this is the most thorough test prep I’ve seen for the checkride. Amazing bang for the buck!

**Developer response:** Appreciate this! I built Answers to the ACS to be as complete as possible for the best value. Glad you agree.

### 5/5 — Best study guide

*2025-02-13*

The study guide I‘ve been waiting for.

**Developer response:** Exactly what I want to hear! A lot of resources say they’re “ACS-based,” but my goal with Answers to the ACS is to literally walk through every ACS element in detail so you get exactly what you expect when you open it. Thank you.

### 5/5 — Customer service

*2024-11-17*

I purchased the app and there was an issue being able to access some parts of the app. I emailed them using the contact us email and stated the issue I was having. I did not expect to hear back but to my surprise I received an email that same day. Within 24 hours I received another email saying the problem was fixed. I would recommend this app solely based on outstanding customer service.  I can’t wait to dig into the content. 

Thanks so much ✈️

**Developer response:** I do my best to support users fast and fix issues quickly, glad we got this squared away. Thank you very much for the mention and I hope you love the content.

### 5/5 — Amazing Resource

*2024-05-21*

An amazing resource to have for both Instructor and Student.

**Developer response:** Love hearing this. Making it useful for both instructors and students is a big goal, thank you for the review.
