### 1/5 — Don’t recommend

*2026-05-01, version 1.14.7*

Downloaded this excited to practice only to realize EVERYTHING, yes everything costs money. $99 per MONTH.

### 1/5 — Cost is wild!

*2026-03-30, version 1.14.2*

Just trying to find a free SAT help app- this clearly isn’t it!!!!! Over 200 dollars?????

### 2/5 — Crashed?!?

*2026-02-04, version 1.12.1*

The app was so what helpful but then sudden the app crashed on me and it’s been like that for two days already! I have been stuck at the “something went wrong” page , and I have tried reinstalling, restarting my phone, and updating the app and nothing worked.

### 1/5 — It’s not free. Subscription $100/month.

*2026-02-04, version 1.12.1*

Lying about price. They require subscription $100 monthly

### 1/5 — Not optimized for phone

*2026-01-05, version 1.10.2*

My kid has this on his Pixel and can’t even read the math questions.

### 1/5 — Waste of money

*2025-11-28, version 1.10.0*

It’s a cheap copy of Duolingo

### 1/5 — Behind a Paywall

*2025-11-26, version 1.10.0*

Looked into this app to start SAT prep, was very happy it was free to use since I didn’t want to commit to paying to any app at the current moment, as soon as I started signing up right after the question about my target score it took me to a paywall screen where I had two options either paying a 12 month subscription or a one month subscription there was no button to X out or continue. I tried reloading the app multiple times. Nothing worked.

### 2/5 — Decent but overpriced

*2025-11-05, version 1.9.0*

Poor copy of Duolingo’s UI, okay practice but it’s nothing to write home about. Its very surface level and I can’t believe they’re charging for it, not even a free tier, you have to pay for everything. I don’t recommend to anyone who’s just looking for a quick way to study, flash cards are better.

### 1/5 — Not free

*2025-10-31, version 1.8.0*

I’m confused to as of why the Instagram review as well as the reviews are saying the app is free. When creating your profile, it won’t let you proceed to questions unless you select a payment plan.

### 5/5 — Easily the BEST FREE SAT resource out there!

*2025-09-19, version 1.6.2*

I had yet to find an SAT resource that actually made studying for this test not boring. (thank you Linus for doing such an awesome job of making my SAT journey FUN!) The roadmap is super easy to work through, and I appreciate the bite-sized lessons covering all SAT material. It’s so much more manageable in comparison to other SAT resources, so thank you so much. Linus is the best!!
