I love the ease of navigating the app and the aesthetic! Info and explanations are so helpful! Thank you to the CLS team! ### 1/5 — Scam , don't upgrade *2024-06-25* I upgraded the app for $39.99 , a week ago and it has not upgraded yet!!. The upgrade part Is a scam . ### 1/5 — Doesn’t open *2024-01-22* Purchased upgrade but app opens up to a white screen. Won’t allow me to proceed after purchase. ### 1/5 — Didn’t help *2023-04-27* This is app not helping so don’t buy it!! ### 4/5 — So far not a bad tool to have on the go! *2023-01-01* Like the title says, I’m not carrying a review book around with me everywhere I go while I prep for my boards so this is an excellent way to review Note: a few small issues on my end: The subscript 2 for BB (ie R2r1) doesn’t show clearly, looks like a zero And there is a question regarding how long plasma has to be frozen, the wording needs to be more specific (PF24 vs FFP) Otherwise certainly a great tool to use ### 1/5 — Great concept but very repetitive, just basic questions, and way too expensive *2022-11-02* I love the idea but I want to be doing more complex level 2 and 3 questions if I’m going to pay this much money. Love the idea but right now would not recommend buying this for students. ### 1/5 — Crashes *2022-10-03* iPad crashes every time I try to increase the number of questions greater than 10. ### 1/5 — No help *2022-07-13, version 1.4.0* The question from this apps didn’t help don’t get it it’s waste of money. ### 2/5 — Not worth the money *2022-06-12* This app is great for doing questions on the go. Some of the explanations contain memory devices which I also found helpful. That being said, the questions were really repetitive and way too basic compared to what I ended up facing on the exam. This app would be great if it was $10. $40 is way too much. ### 1/5 — Crashes *2021-08-13* iPad crashes every time I try to increase the number of questions greater than 10. Works fine on my iPhone but the tiny iPhone screen is very inconvenient. ## Frequently asked questions about Clinical Lab Science Review ### What is Clinical Lab Science Review?
